What is the dorsum sellae?

The dorsum sellae is the square shaped process of the sphenoid bone. It ascends superiorly from the posterior part of the sphenoid body to form the posterior wall of the sella turcica.

Are the tubercles of the superior angle of the dorsum sellae?

The dorsum sellae is part of the sphenoid bone in the skull. Together with the basilar part of the occipital bone it forms the clivus....

What is Tuberculum Sella?

The tuberculum sellae forms the anterior wall of the sella turcica, which houses the pituitary gland. It is an elongated ridge located immediately posterior to the chiasmatic groove, hence is related to the optic chiasm and anterior portions of the optic tracts.

Is the occipital bone?

What is the Diaphragma Sellae?

The diaphragma sellae is a sheet of dura mater that forms the roof of the pituitary fossa. It is described as a two-layer sheet of dura mater that merges anteriorly with the dura covering the planum sphenoidale and the anterior cranial fossa and posteriorly with the dura covering the dorsum sellae and the clivus.

What is tuberculum Sella?

The tuberculum sellae forms the anterior wall of the sella turcica, which houses the pituitary gland. It is an elongated ridge located immediately posterior to the chiasmatic groove, hence is related to the optic chiasm and anterior portions of the optic tracts.

Does the occipital bone move?

The occiput and the mastoid part of the temporal bone normally move in opposing directions to each other: in the inspiration phase the border of the occiput moves in an anterior direction, while the border of the mastoid part slides posterior.

Why does the back of my skull stick out?

The bony growth, which is known as an “external occipital protuberance,” can be found at the back of the skull, just above the base of the neck. The role of the projection is to distribute force over a large area of the bone's surface and it can arise at spots near ligaments, tendons, or joints.

What is the function of diaphragma sellae?

The diaphragma sellae forms the roof of the sella turcica (see Figure 10-1). It covers the pituitary gland, except for a small central opening in its center, which transmits the pituitary stalk.

Why does my occipital bone hurt?

What causes occipital neuralgia? Occipital neuralgia may occur spontaneously, or as the result of a pinched nerve root in the neck (from arthritis, for example), or because of prior injury or surgery to the scalp or skull. Sometimes "tight" muscles at the back of the head can entrap the nerves.

Is an inion bump normal?

Occipital spurs, also called as occipital knob, occipital bun, chignon or inion hook, is an exaggerated external occipital protuberance (EOP). It is frequently discussed in anthropological literature as a Neanderthal trait but hardly reported and considered as a normal variant in medical literature.

What is the bump on the back of your skull called?

An occipital bun, also called occipital spurs, occipital knob, chignon hooks, PBS head or inion hooks, is a prominent bulge or projection of the occipital bone at the back of the skull. It is important in scientific descriptions of classic Neanderthal crania.

What does the diaphragma sellae cover?

The diaphragma sellae is a sheet of dura mater that forms the roof of the pituitary fossa. It is described as a two-layer sheet of dura mater that merges anteriorly with the dura covering the planum sphenoidale and the anterior cranial fossa and posteriorly with the dura covering the dorsum sellae and the clivus.

What does occipital nerve pain feel like?

Occipital Neuralgia is a condition in which the occipital nerves, the nerves that run through the scalp, are injured or inflamed. This causes headaches that feel like severe piercing, throbbing or shock-like pain in the upper neck, back of the head or behind the ears.

Will occipital neuralgia ever go away?

Does occipital neuralgia go away? Occipital neuralgia may go away with time if the cause of your occipital nerve inflammation is corrected.

Why is the back of my skull lumpy?

A bump on the back of the head has many possible causes, including injuries, cysts, fatty growths, inflamed hair follicles, and bone spurs. Bumps on this part of the body can be hard or soft, and they can vary in size. Injuries are a common cause of bumps and lumps on the back of the head.
