What does the anterior cranial fossa control?

The anterior cranial fossa is a depression in the cranial base, which primarily supports the large frontal lobes of the cerebral hemispheres. However, in the center of the anterior cranial fossa are small depressions, the olfactory fossae, which support the olfactory bulbs (Figs. 2.1, 2.6, and 2.7).

What is the fossa in the brain?

The posterior fossa is a small space in the skull, found near the brainstem and cerebellum. If a tumor grows in the area of the posterior fossa, it can block the flow of spinal fluid and cause increased pressure on the brain and spinal cord. Most tumors of the posterior fossa are primary brain cancers.

What bone is the anterior cranial fossa on?

frontal bone
The anterior cranial fossa is formed by the orbital part of the frontal bone, the cribriform plate and crista galli of the ethmoid bone, and the lesser wings and anterior part of the body (jugum sphenoidale and prechiasmatic sulcus) of the sphenoid bone (Standing, 2015).

What part of the brain is in the anterior cranial fossa?

frontal lobes
The anterior cranial fossa constitutes the floor of the cranial vault which houses the frontal lobes of the brain.

Where is the anterior fossa?

Each fossa accommodates a different part of the brain. The anterior cranial fossa is the most shallow and superior of the three cranial fossae. It lies superiorly over the nasal and orbital cavities. The fossa accommodates the anteroinferior portions of the frontal lobes of the brain.

What is fossa in bone?

Fossa – A shallow depression in the bone surface. Here it may receive another articulating bone or act to support brain structures. Examples include trochlear fossa, posterior, middle, and anterior cranial fossa.

What does fossa mean in medical terms?

depression
Fossa = a depression or hollow, (literal translation = ditch, trench, Latin) Iliac fossa = the depression in the inner surface of the ileum. Fossa ovalis = depression on wall of the right atrium that separates the right atrium from the left.

Where is fossa located?

A cranial fossa is formed by the floor of the cranial cavity. There are three distinct cranial fossae: Anterior cranial fossa (fossa cranii anterior), housing the projecting frontal lobes of the brain….

What is middle cranial fossa?

The middle cranial fossa is a butterfly-shaped depression of the skull base, which is narrow in the middle and wider laterally. It houses the temporal lobes of the cerebrum.

Where is the fossa in the body?

The fossa is located behind the zygomatic process of the frontal bone in the anterior and lateral part of the orbital roof.

What is a tubercle in medical terms?

A tubercle is a small rounded point of a bone. It also refers to a nodule attached to bone, mucous membrane (moist layer lining parts of the body), or skin. The term tubercle is less commonly used to refer to skin irritation resulting from a tuberculosis (TB) infection.

Where is the anterior fossa located?

The anterior cranial fossa is a depression in the floor of the cranial base which houses the projecting frontal lobes of the brain.
