| fossa pterygoidea | The fossa formed by the divergence posteriorly of the plates of the pterygoid process of the sphenoid bone; it lodges the origin of medial pterygoid and the tensor palati muscles. Synonym: fossa pterygoidea. (05 Mar 2000) |
|---|---|
| fossa pterygopalatina | Sphenomaxillary fossa, a small pyramidal space, housing the pterygopalatine ganglion, between the pterygoid process, the maxilla, and the palatine bone. Synonym: fossa pterygopalatina, Bichat's fossa, pterygomaxillary fossa, sphenomaxillary fossa. (05 Mar 2000) |
| fossa radialis humeri | A shallow depression on the anterior aspect of the distal humerus, superior to the capitulum of the humerus and lateral to the coronoid fossa, in which the margin of the head of the radius rests when the elbow is in extreme flexion. Synonym: fossa radialis humeri. (05 Mar 2000) |
| fossa retromandibularis | The depression inferior to the auricle and posterior to the ramus and angle of the mandible. Synonym: fossa retromandibularis. (05 Mar 2000) |
| fossa rhomboidea | The floor of the fourth ventricle of the brain, formed by the ventricular surface of the rhombencephalon. Synonym: fossa rhomboidea. (05 Mar 2000) |
| fossa sacci lacrimalis | A fossa formed by the lacrimal bone and the frontal process of the maxilla, lodging the lacrimal sac. Synonym: fossa sacci lacrimalis. (05 Mar 2000) |
| fossa scaphoidea ossis sphenoidalis | A boat-shaped hollow. A longitudinal hollow on the posterior surface of the superior portion (root) of the medial pterygoid plate; it gives origin to the tensor veli palati muscle. Synonym: fossa scaphoidea ossis sphenoidalis, Cruveilhier's fossa, fossa navicularis Cruveilhier, scaphoid fossa of sphenoid bone. Synonym: scapha. (05 Mar 2000) |
| fossa scarpae major | A triangular space at the upper part of the thigh, bounded by the sartorius and adductor longus muscles and the inguinal ligament, with a floor formed laterally by the iliopsoas muscle and medially by the pectineus muscle; the branches of the femoral nerve are distributed within the femoral triangle; it is bisected by the femoral vessels, which enter the adductor canal at its apex. Synonym: trigonum femorale, fossa scarpae major, Scarpa's triangle, subinguinal triangle. (05 Mar 2000) |
| fossa subarcuata | An irregular depression on the posterior surface of the petrous portion of the temporal bone just below its crest and above and lateral to the internal acoustic meatus. In the foetus, the flocculus of the cerebellum rests here; in the adult, a small vein enters the bone here. Synonym: fossa subarcuata, floccular fossa, hiatus subarcuatus. (05 Mar 2000) |
| fossa submandibularis | The depression on the medial surface of the body of the mandible inferior to the mylohyoid line in which the submandibular gland is lodged. Synonym: fovea submandibularis, fossa submandibularis, fovea submaxillaris, submaxillary fossa. (05 Mar 2000) |
| fossa subscapularis | The concave ventral aspect of the body of the scapula giving origin to the subscapularis muscle. Synonym: fossa subscapularis. (05 Mar 2000) |
| fossa supraclavicularis major | The triangle bounded by the clavicle, the omohyoid muscle, and the sternocleidomastoid muscle; it contains the subclavian artery and vein. Synonym: fossa supraclavicularis major, trigonum omoclaviculare, greater supraclavicular fossa, omoclavicular triangle, subclavian triangle. (05 Mar 2000) |
| fossa supraclavicularis minor | A triangular space between the two heads of origin of the sternocleidomastoid muscle. Synonym: fossa supraclavicularis minor. (05 Mar 2000) |
| fossa supraspinata | The hollow on the dorsal aspect of the scapula above the spine, lodging the supraspinatus muscle. Synonym: fossa supraspinata. (05 Mar 2000) |
| fossa supratonsillaris | The interval between the palatoglossal and palatopharyngeal arches above the tonsil, most obvious after the tonsil has regressed in the adult. Synonym: fossa supratonsillaris, supratonsillar recess, Tourtual's sinus. (05 Mar 2000) |
