| 释义 |
| Name = Subarcuate fossa | Latin = Fossa subarcuata ossis temporalis | Image = Gray138.png | Caption = Left temporal bone. Inner surface. (Subarcuate fossa not labeled, but aquaeductus vestibuli labeled at lower right.) | Image2 = Gray193.png | Caption2 = Base of the skull. Upper surface. (Subarcuate fossa not labeled, but temporal bone is identified in pink, and "Eminentia arcuata" (i.e. arcuate eminence, corresponding to the superior semicircular canal) is labeled.) }} In the temporal bone at the sides of the skull, above and between the aquæductus vestibuli is an irregular depression which lodges a process of the dura mater and transmits a small vein and the subarcuate artery[1] a branch of the meatal segment of anterior inferior cerebellar artery, which is an end artery that supplies blood to the inner ear; in the infant this depression is represented by a large fossa, the subarcuate fossa, which extends backward as a blind tunnel under the superior semicircular canal. It is extensive in most primates (except for great apes) and nearly all mammals. In these animals, the subarcuate fossa houses a part of the cerebellum, the petrosal lobe.[2][3] References{{Gray's}}1. ^{{cite journal |vauthors=Mom T, Chazal J, Gabrillargues J, Gilain L, Avan P |title=Cochlear blood supply: an update on anatomy and function |journal=Fr ORL |volume=88 |pages=81–8 |year=2005 |url=http://www.rforl.com/PDF/UK0508801.pdf}} 2. ^{{cite journal |vauthors=Gannon PJ, Eden AR, Laitman JT |title=The subarcuate fossa and cerebellum of extant primates: comparative study of a skull-brain interface |journal=Am J Phys Anthropol |volume=77 |issue=2 |pages=143–64 |date=Oct 1988 |pmid=3207165 |doi=10.1002/ajpa.1330770202 }} 3. ^{{cite journal |vauthors=Jeffery N, Ryan TM, Spoor F |title=The primate subarcuate fossa and its relationship to the semicircular canals part II: adult interspecific variation |journal=J Hum Evol |volume=55 |issue=2 |pages=326–39 |date=Aug 2008 |pmid=18395770 |doi=10.1016/j.jhevol.2008.02.010 }} External links
