cubital fossa temporal fossa. On the side of the skull, a large fan-shaped depression containing the temporalis muscle. The fossa's upper edge forms a broad crescent (the temporal lines) along the frontal, parietal, and temporal bones, from the upper outer edge of the orbit to the most posterior edge of the zygomatic arch.n the anterior surface of the lower end of the humerus, a depression proximal to the trochlea and between the lateral and medial epicondyles; it is analogous to the olecranon fossa on the opposite side of the humerus.

- The fossa (Cryptoprocta ferox) is a unique carnivore, endemic to Madagascar, is EDGE Mammal number 43, and is today's IUCN Species of the Day. There has ... There has been considerable dispute over the taxonomy of the fossa. It was originally classified as a felid due to its cat-like head and body-shape. However, the fossa's resemblance to cats is a result of convergent evolution. Researchers later placed the fossa in the family Viverridae due to its apparent resemblance to civets and genets.

Anterior nasal aperture The anterior nasal aperture (piriform or pyriform aperture) is a heart-or pear-shaped opening in the human skull. Its long axis is vertical, and narrow end upward; in the recent state it is much contracted by the lateral nasal cartilage and the greater and lesser alar cartilages of the nose.

Mandibular fossa In the temporal bone, the mandibular fossa is bounded, in front, by the articular tubercle; behind, by the tympanic part of the temporal bone, which separates it from the external acoustic meatus; it is divided into two parts by a narrow slit, the petrotympanic fissure (Glaserian fissure).

Fossa Fossa Classification and Evolution The Fossa is a medium-sized carnivore that is found exclusively on the island of Madagascar. The Fossa belongs to the Malagasy Carnivores group which are thought to have descended from Mongoose-like ancestors that arrived on Madagascar from Africa up to 24 million years ago.he tail of the Fossa is around the same length as it's body and plays a crucial role in helping the animal to balance whilst it is leaping through the trees. The Fossa has short but dense red to dark brown fur and a small cat-like head and a dog-like snout, with large forward facing eyes and small, rounded ears.

- The ischioanal fossa is a paired triangular-shaped space lateral to the anal canal with an apex directed anteromedially towards the pubic symphysis. Each ischioanal fossa is separated from the other by the anococcygeal body but they do still communicate superiorly to this and posterior to the anal canal.

Skull Base Anatomy Anterior cranial fossa and body of the sphenoid. The greater portion of the anterior floor is convex and grooved by the frontal lobe gyri. This portion of the skull base consists of the orbital portion of the frontal bone. The ethmoid bone forms the central part of the floor, which is the deepest area of the anterior cranial fossa. In the center of this region is the cribriform plate, through which the olfactory tracts pass.
