In anatomy, a fossa (/ ˈ f ɒ s ə /; [1] [2] pl.: fossae (/ ˈ f ɒ s iː / or / ˈ f ɒ s aɪ /); from Latin 'ditch, trench') is a depression or hollow, usually in a bone, such as the hypophyseal fossa (the depression in the sphenoid bone). [3] Some examples include: In the skull: Cranial fossa. Anterior cranial fossa; Middle cranial fossa ...
A fossa (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. [15] A meatus is a short canal that opens to another part of the body. [16] An example is the external auditory meatus. A fovea (Latin: pit) is a small pit, usually on the head of a ...
Anteriorly, the posterior cranial fossa is bounded by the dorsum sellae, posterior aspect of the body of sphenoid bone, and the basilar part of occipital bone/clivus. [2] Laterally, it is bounded by the petrous parts and mastoid parts of the temporal bones, and the lateral parts of occipital bone. [2]
It is composed of 270 bones at the time of birth, [2] but later decreases to 206: 80 bones in the axial skeleton and 126 bones in the appendicular skeleton. 172 of 206 bones are part of a pair and the remaining 34 are unpaired. [3] Many small accessory bones, such as sesamoid bones, are not included in this.
The iliac fossa is bounded above by the iliac crest, and below by the arcuate line. It is bordered in front and behind by the anterior and posterior borders of the ilium. The iliac fossa gives origin to the iliacus muscle. [1] The obturator nerve passes around the iliac fossa. [2] It is perforated at its inner part by a nutrient canal.
The trunk of the body contains, from superior to inferior, the thoracic region encompassing the chest [1] the mammary region encompassing each breast; the sternal region encompassing the sternum; the abdominal region encompassing the stomach area; the umbilical region is located around the navel; the coxal region encompassing the lateral (side ...
