Examples
“And the presence of the glands in this location might explain another unusual aspect of metriorhynchid cranial anatomy, namely the strange elongate, groove-like antorbital fossae present in these animals (the antorbital fossa is an accessory opening present on the side of the skull in archosaurs).”
“Response to David: some books say that fossa is pronounced 'foosh', which would agree with your comment.”
“Dorian - a "fossa" - looks to us like a cross between a dog, a cat, a bat and a gerbil - or maybe a bear.”
“Similarly, the fossa is related to more familiar cats through the suborder Feliformia, but lie in a different family (Eupleridae) than the lions, tigers and housecats we’re familiar with (Felidae).”

“On the outside of the rectal wall, at the terminal portion, there is also much loose, fatty (areolar) tissue filling the ischio-rectal fossa, which is very prone to suppuration, and inflammation here is called periproctitis.”
“At the upper part of the fossa is a transverse depression, where the bone appears to be bent on itself along a line at right angles to and passing through the center of the glenoid cavity, forming a considerable angle, called the subscapular angle; this gives greater strength to the body of the bone by its arched form, while the summit of the arch serves to support the spine and acromion.”
“On the floor of the fossa are the popliteal vessels, the vein being superficial to the artery and united to it by dense areolar tissue; the vein is a thick-walled vessel, and lies at first lateral to the artery, and then crosses it posteriorly to gain its medial side below; sometimes it is double, the artery lying between the two veins, which are usually connected by short transverse branches.”
“The peritoneum of the anterior pelvic wall covers the superior surface of the bladder, and on either side of this viscus forms a depression, termed the paravesical fossa, which is limited laterally by the fold of peritoneum covering the ductus deferens.”
“Behind this part of the fossa is a small conical eminence; this is the representative of a prominent tubercle which, in some mammals, descends behind the condyle of the mandible, and prevents its backward displacement.”
“The fossa is a narrow chink situated between the mesentery of the small intestine, the ileum, and the small portion of the cecum behind. (b) The inferior ileocecal fossa is situated behind the angle of junction of the ileum and cecum.”
