What does fossa in anatomy mean?
(Entry 1 of 2): an anatomical pit, groove, or depression.
What is the purpose of Fossa inside the skull?
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 bones contain a fossa?
The middle cranial fossa consists of three bones – the sphenoid bone and the two temporal bones.
What are fossa in the human skull?
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 does fossa stand for?
45791. Anatomical terminology. In anatomy, a fossa (/ˈfɒsə/; plural fossae (/ˈfɒsiː/ or /ˈfɒsaɪ/); from the Latin ” fossa “, ditch or trench) is a depression or hollow, usually in a bone, such as the hypophyseal fossa (the depression in the sphenoid bone).
Where is the Pterygopalatine fossa?
The pterygopalatine fossa (PPF) is a small, clinically inaccessible, fat-filled space located in the deep face that serves as a major neurovascular crossroad between the oral cavity, nasal cavity, nasopharynx, orbit, masticator space, and the middle cranial fossa.
Where is the middle fossa?
The middle cranial fossa, deeper than the anterior cranial fossa, is narrow medially and widens laterally to the sides of the skull. It is separated from the posterior fossa by the clivus and the petrous crest.
Where is Infratemporal fossa located?
The infratemporal fossa is a complex area located at the base of the skull, deep to the masseter muscle. It is closely associated with both the temporal and pterygopalatine fossae and acts as a conduit for neurovascular structures entering and leaving the cranial cavity.
What passes through Pterygoid fossa?
Pterygoid canal – runs from the middle cranial fossa and through the medial pterygoid plate. It carries the nerve, artery and vein of the pterygoid canal.
What is an example of a fossa?
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 is difference between Fossa and cavity?
is that cavity is a hole or hollow depression while fossa is (anatomy) a pit, groove, cavity, or depression, of greater or less depth or fossa can be a carnivorous mammal endemic to madagascar,.
What does process mean in anatomy?
Process: In anatomy, a projection from a structure. For example, the process of the mandible is the part of the lower jaw that projects forward.
What does the fossa eat?
Well more than half of this carnivore’s diet consists of lemurs. It will also feed opportunistically on birds, baby bush pigs, civet cats, fish, rats, eggs, snakes, frogs, and insects. Occasionally, the fossa will raid domestic chickens, small sheep, and goats.
Is a fossa a cat?
The fossa (Cryptoprocta ferox) is the largest carnivorous mammal on the island of Madagascar. They can reach nearly six feet in length, with half of that due to their long tails. They look like a cross between a cat, a dog, and a mongoose. Fossas have slender bodies, muscular limbs, and short, reddish-brown coats.
What is skull base?
At the base of the skull is bone that supports 4 brain components—the frontal lobe, temporal lobe, brain stem, and cerebellum. The skull base offers support from the bottom of the brain. Think of it as the floor of the skull, where the brain sits. Five bones make up the skull base.
