The skull is made up of a number of fused flat bones , and contains many foramina , fossae , processes , and several cavities or sinuses.

In zoology there are openings in the skull called fenestrae. The human skull is the bony structure that forms the head in the human skeleton. It supports the structures of the face and forms a cavity for the brain.

Like the skulls of other vertebrates, it protects the brain from injury. The skull consists of three parts, of different embryological origin—the neurocranium , the sutures, and the facial skeleton also called the membraneous viscerocranium.

The neurocranium or braincase forms the protective cranial cavity that surrounds and houses the brain and brainstem. The membranous viscerocranium includes the mandible.

Except for the mandible , all of the bones of the skull are joined together by sutures — synarthrodial immovable joints formed by bony ossification , with Sharpey's fibres permitting some flexibility.

Sometimes there can be extra bone pieces within the suture known as wormian bones or sutural bones. Most commonly these are found in the course of the lambdoid suture.

The human skull is generally considered to consist of twenty-two bones —eight cranial bones and fourteen facial skeleton bones.

In the neurocranium these are the occipital bone , two temporal bones , two parietal bones , the sphenoid , ethmoid and frontal bones.

The bones of the facial skeleton 14 are the vomer , two inferior nasal conchae , two nasal bones , two maxilla , the mandible , two palatine bones , two zygomatic bones , and two lacrimal bones.

Some sources count a paired bone as one, or the maxilla as having two bones as its parts ; some sources include the hyoid bone or the three ossicles of the middle ear but the overall general consensus of the number of bones in the human skull is the stated twenty-two.

Some of these bones—the occipital, parietal, frontal, in the neurocranium, and the nasal, lacrimal, and vomer, in the facial skeleton are flat bones.

The skull also contains sinuses , air-filled cavities known as paranasal sinuses , and numerous foramina. The sinuses are lined with respiratory epithelium.

Their known functions are the lessening of the weight of the skull, the aiding of resonance to the voice and the warming and moistening of the air drawn into the nasal cavity.

The foramina are openings in the skull. The largest of these is the foramen magnum that allows the passage of the spinal cord as well as nerves and blood vessels.

The many processes of the skull include the mastoid process and the zygomatic processes. The fenestrae from Latin, meaning windows are openings in the skull.

The temporal fenestrae are anatomical features of the skulls of several types of amniotes , characterised by bilaterally symmetrical holes fenestrae in the temporal bone.

Depending on the lineage of a given animal, two, one, or no pairs of temporal fenestrae may be present, above or below the postorbital and squamosal bones.

The upper temporal fenestrae are also known as the supratemporal fenestrae, and the lower temporal fenestrae are also known as the infratemporal fenestrae.

The presence and morphology of the temporal fenestra are critical for taxonomic classification of the synapsids, of which mammals are part.

Physiological speculation associates it with a rise in metabolic rates and an increase in jaw musculature. The earlier amniotes of the Carboniferous did not have temporal fenestrae but two more advanced lines did: the synapsids mammal-like reptiles and the diapsids most reptiles and later birds.

As time progressed, diapsids' and synapsids' temporal fenestrae became more modified and larger to make stronger bites and more jaw muscles.

Dinosaurs, which are diapsids, have large advanced openings, and their descendants, the birds, have temporal fenestrae which have been modified.

Mammals, which are synapsids, possess one fenestral opening in the skull, situated to the rear of the orbit. There are four types of amniote skull, classified by the number and location of their temporal fenestrae.

These are:. The jugal is a skull bone found in most reptiles, amphibians, and birds. In mammals, the jugal is often called the zygomatic bone or malar bone.

The prefrontal bone is a bone separating the lacrimal and frontal bones in many tetrapod skulls. The skull of fishes is formed from a series of only loosely connected bones.

Lampreys and sharks only possess a cartilaginous endocranium, with both the upper and lower jaws being separate elements. Bony fishes have additional dermal bone , forming a more or less coherent skull roof in lungfish and holost fish.

The lower jaw defines a chin. The simpler structure is found in jawless fish , in which the cranium is normally represented by a trough-like basket of cartilaginous elements only partially enclosing the brain, and associated with the capsules for the inner ears and the single nostril.

Distinctively, these fish have no jaws. Cartilaginous fish , such as sharks and rays, have also simple, and presumably primitive, skull structures.

The cranium is a single structure forming a case around the brain, enclosing the lower surface and the sides, but always at least partially open at the top as a large fontanelle.

The most anterior part of the cranium includes a forward plate of cartilage, the rostrum , and capsules to enclose the olfactory organs.

Behind these are the orbits, and then an additional pair of capsules enclosing the structure of the inner ear. Finally, the skull tapers towards the rear, where the foramen magnum lies immediately above a single condyle , articulating with the first vertebra.

There are, in addition, at various points throughout the cranium, smaller foramina for the cranial nerves. The jaws consist of separate hoops of cartilage, almost always distinct from the cranium proper.

In ray-finned fish , there has also been considerable modification from the primitive pattern. The roof of the skull is generally well formed, and although the exact relationship of its bones to those of tetrapods is unclear, they are usually given similar names for convenience.

Other elements of the skull, however, may be reduced; there is little cheek region behind the enlarged orbits, and little, if any bone in between them.

The upper jaw is often formed largely from the premaxilla , with the maxilla itself located further back, and an additional bone, the symplectic, linking the jaw to the rest of the cranium.

Although the skulls of fossil lobe-finned fish resemble those of the early tetrapods, the same cannot be said of those of the living lungfishes. The skull roof is not fully formed, and consists of multiple, somewhat irregularly shaped bones with no direct relationship to those of tetrapods.

The upper jaw is formed from the pterygoids and vomers alone, all of which bear teeth. Much of the skull is formed from cartilage , and its overall structure is reduced.

The skulls of the earliest tetrapods closely resembled those of their ancestors amongst the lobe-finned fishes. The skull roof is formed of a series of plate-like bones, including the maxilla , frontals , parietals , and lacrimals , among others.

It is overlaying the endocranium , corresponding to the cartilaginous skull in sharks and rays. The various separate bones that compose the temporal bone of humans are also part of the skull roof series.

A further plate composed of four pairs of bones forms the roof of the mouth; these include the vomer and palatine bones. The base of the cranium is formed from a ring of bones surrounding the foramen magnum and a median bone lying further forward; these are homologous with the occipital bone and parts of the sphenoid in mammals.

Finally, the lower jaw is composed of multiple bones, only the most anterior of which the dentary is homologous with the mammalian mandible.

In living tetrapods, a great many of the original bones have either disappeared or fused into one another in various arrangements.

Birds have a diapsid skull, as in reptiles, with a prelachrymal fossa present in some reptiles. The skull has a single occipital condyle.

The eye occupies a considerable amount of the skull and is surrounded by a sclerotic eye-ring, a ring of tiny bones. This characteristic is also seen in reptiles.

Living amphibians typically have greatly reduced skulls, with many of the bones either absent or wholly or partly replaced by cartilage.

The fusion between the various bones is especially notable in birds, in which the individual structures may be difficult to identify.

The skull is a complex structure; its bones are formed both by intramembranous and endochondral ossification. The skull roof bones, comprising the bones of the facial skeleton and the sides and roof of the neurocranium, are dermal bones formed by intramembranous ossification, though the temporal bones are formed by endochondral ossification.

The endocranium , the bones supporting the brain the occipital , sphenoid , and ethmoid are largely formed by endochondral ossification.

Thus frontal and parietal bones are purely membranous. The anterior cranial fossa changes especially during the first trimester of pregnancy and skull defects can often develop during this time.

At birth, the human skull is made up of 44 separate bony elements. During development, many of these bony elements gradually fuse together into solid bone for example, the frontal bone.

The bones of the roof of the skull are initially separated by regions of dense connective tissue called fontanelles. There are six fontanelles: one anterior or frontal , one posterior or occipital , two sphenoid or anterolateral , and two mastoid or posterolateral.

At birth, these regions are fibrous and moveable, necessary for birth and later growth. This growth can put a large amount of tension on the "obstetrical hinge", which is where the squamous and lateral parts of the occipital bone meet.

A possible complication of this tension is rupture of the great cerebral vein. As growth and ossification progress, the connective tissue of the fontanelles is invaded and replaced by bone creating sutures.

The five sutures are the two squamous sutures , one coronal , one lambdoid , and one sagittal suture. The posterior fontanelle usually closes by eight weeks, but the anterior fontanel can remain open up to eighteen months.

The anterior fontanelle is located at the junction of the frontal and parietal bones; it is a "soft spot" on a baby's forehead. Careful observation will show that you can count a baby's heart rate by observing the pulse pulsing softly through the anterior fontanelle.

The skull in the neonate is large in proportion to other parts of the body. The facial skeleton is one seventh of the size of the calvaria.

In the adult it is half the size. The base of the skull is short and narrow, though the inner ear is almost adult size. Craniosynostosis is a condition in which one or more of the fibrous sutures in an infant skull prematurely fuses, [11] and changes the growth pattern of the skull.

A copper beaten skull is a phenomenon wherein intense intracranial pressure disfigures the internal surface of the skull.

The condition is most common in children. Injuries to the brain can be life-threatening. In these cases the raised intracranial pressure can cause herniation of the brain out of the foramen magnum "coning" because there is no space for the brain to expand; this can result in significant brain damage or death unless an urgent operation is performed to relieve the pressure.

This is why patients with concussion must be watched extremely carefully. Dating back to Neolithic times, a skull operation called trepanning was sometimes performed.

This involved drilling a burr hole in the cranium. Examination of skulls from this period reveals that the patients sometimes survived for many years afterward.

It seems likely that trepanning was also performed purely for ritualistic or religious reasons. Nowadays this procedure is still used but is normally called a craniectomy.

In March , for the first time in the U. She had been suffering from hyperostosis , which increased the thickness of her skull and compressed her brain.

A study conducted in by the researchers of Harvard Medical School in Boston, funded by National Institutes of Health NIH suggested that instead of travelling via blood , there are "tiny channels" in the skull through which the immune cells combined with the bone marrow reach the areas of inflammation after an injury to the brain tissues.

Surgical alteration of sexually dimorphic skull features may be carried out as a part of facial feminization surgery , a set of reconstructive surgical procedures that can alter male facial features to bring them closer in shape and size to typical female facial features.

Artificial cranial deformation is a largely historical practice of some cultures. Cords and wooden boards would be used to apply pressure to an infant's skull and alter its shape, sometimes quite significantly.

This procedure would begin just after birth and would be carried on for several years. Like the face, the skull and teeth can also indicate a person's life history and origin.

Forensic scientists and archaeologists use metric and nonmetric traits to estimate what the bearer of the skull looked like.

The German physician Franz Joseph Gall in around formulated the theory of phrenology , which attempted to show that specific features of the skull are associated with certain personality traits or intellectual capabilities of its owner.

His theory is now considered to be pseudoscientific. In the mid-nineteenth century, anthropologists found it crucial to distinguish between male and female skulls.

An anthropologist of the time, James McGrigor Allan , argued that the female brain was similar to that of an animal. McGrigor then concluded that women's brains were more analogous to infants, thus deeming them inferior at the time.

These cranial measurements are the basis of what is known as craniology. The human cranium , the part that contains the brain, is globular and relatively large in comparison with the face.

In most other animals the facial portion of the skull, including the upper teeth and the nose , is larger than the cranium. In humans the skull is supported by the highest vertebra, called the atlas, permitting nodding motion.

The atlas turns on the next-lower vertebra, the axis, to allow for side-to-side motion. In humans the base of the cranium is the occipital bone , which has a central opening foramen magnum to admit the spinal cord.

The parietal and temporal bones form the sides and uppermost portion of the dome of the cranium, and the frontal bone forms the forehead; the cranial floor consists of the sphenoid and ethmoid bones.

The facial area includes the zygomatic , or malar, bones cheekbones , which join with the temporal and maxillary bones to form the zygomatic arch below the eye socket; the palatine bone; and the maxillary, or upper jaw, bones.

The nasal cavity is formed by the vomer and the nasal, lachrymal, and turbinate bones. In infants the sutures joints between the various skull elements are loose, but with age they fuse together.

Many mammals , such as the dog , have a sagittal crest down the centre of the skull; this provides an extra attachment site for the temporal muscles , which close the jaws.
