Difference Between Male and Female Skull

Male vs Female Skull
 

The human skull is an important part of the skeletal system, which basically provides sites for facial muscle attachments and forms a cranial cavity for the brain.  The skull is made up of two parts that have different embryological differences; (1) neurocranium, which is the protective vault surrounding the brain, and (2) viscerocranium, which is composed of facial bones. There are 22 bones constitute to compose the human skull, and all these bones are joined together, except the mandible. Thus, the mandible is the only bone of the human skull which can be moved freely. The human skull contains several sinuses; air- filled cavities lined by respiratory epithelium. The exact function of these sinuses is still debatable. However, they may be important to reduce skull weight, provide voice resonance, and warm and moisture inspired air.  Presence of sutures is a unique characteristic of skull. The sutures are a type of fibrous joint only occurs in the skull. There are 17 sutures on the human skull. Both male and female skulls are made up of 22 bones, but there are some distinguishable features between these two skulls.

Male Skull

The bones of male skull are much heavier than the female skull. The main characteristic features of the male skull include prominent supercillary arches, prominent glabella, eversion of angle of mandible, large mastoid process, and bones with better muscular markings. In addition, the eye orbits are somewhat square shaped in male skull.

Female Skull

Female skull is made up of much lighter bones than males, with smooth surfaces. The frontal and parietal eminences are larger than that of males. The orbits of female skull are rounded and larger. In addition, females show more rounder and more upright foreheads.

What is the difference between Male and Female Skull?

• Generally, male skull is more massive and heavier than female skull.

• Male has a low and sloped frontal bone, whereas the female’s frontal lobe is higher and more rounded.

• The eye orbits of males are somewhat square shaped, lower, relatively smaller with rounded superior margins while the female eye orbits are more circular, higher, larger with very sharp superior margins.

• The lower jaw of male skull is square, with an angle of about 90°. In contrast, the lower jaw of female skull is sloped, an angle greater than 90°.

• Male skull has squarer chin while female skull has V- shaped chin.

• Usually males have thicker bones than females.

• Facial bones of female skull are smoother than that of males.

• Zygomatic bones of males are massive than that of females.

• Suborbital margins are sharper in females, whereas they are more rounded in males.

• The tympanic plate is larger and margins are rounded in males while that is smaller and the margins are less rounded in females.

• Mastoid process is large in males, whereas it is small in females.

• Generally, the width of male skull is greater in males, than that of female.

• Palate of male is larger, broader, and tends to be U- shaped, whereas that of female tends to be a parabola.

• Occipital condyles of males are larger than that of females.
