| tapetum oculi | The outer layer of the retina, consisting of pigmented epithelium. Synonym: ectoretina, stratum pigmenti bulbi, stratum pigmenti retinae, tapetum nigrum, tapetum oculi. (05 Mar 2000) |
|---|---|
| tendo oculi | <anatomy> The fibrous band that attaches the medial ends of the tarsal plates to the maxilla at the medial orbital margin. Synonym: ligamentum palpebrale mediale, ligamentum tarsale internum, tendo oculi, tendo palpebrarum. (05 Mar 2000) |
| equator bulbi oculi | An imaginary line encircling the globe of the eye equidistant from the anterior and posterior poles. Synonym: equator bulbi oculi. (05 Mar 2000) |
| tunica albuginea oculi | <anatomy> The tough white outer coat of the eyeball, covering approximately the posterior five sixths of its surface and continuous anteriorly with the cornea and posteriorly with the external sheath of the optic nerve. Origin: L., Gr. Skleros = hard (18 Nov 1997) |
| tunica externa oculi | The outer layer of the eyeball composed of the sclera and cornea. Synonym: tunica fibrosa bulbi, tunica externa oculi. (05 Mar 2000) |
| tunica vasculosa oculi | The vascular, pigmentary, or middle coat of the eye, comprising the choroid, ciliary body, and iris. Synonym: tunica vasculosa bulbi, Haller's tunica vasculosa, tunica vasculosa oculi, uvea, uveal tract. (05 Mar 2000) |
| lacrimal part of orbicularis oculi muscle | <anatomy> See: orbicularis oculi muscle. Synonym: pars lacrimalis musculi orbicularis oculi, Duverney's muscle, Horner's muscle, musculus tensor tarsi. (05 Mar 2000) |
| fundus oculi | The concave interior of the eye, consisting of the retina, the choroid, the sclera, the optic disk, and blood vessels, seen by means of the ophthalmoscope. (12 Dec 1998) |
| anal sphincter | See: external anal sphincter, internal anal sphincter. (05 Mar 2000) |
| anatomical sphincter | An accumulation of muscular circular fibres or specially arranged oblique fibres the function of which is to reduce partially or totally the lumen of a tube, the orifice of an organ, or the cavity of a viscus; the closing component of a pylorus. (05 Mar 2000) |
| annular sphincter | A short thickening of circular muscular fibres, similar to a ring; a ring-shaped sphincter as opposed to a segmental sphincter. (05 Mar 2000) |
| antral sphincter | Angular sphincter, thickening of the circular muscular layer forming a proposed intermediate sphincter at the level of the angular notch of the stomach. While the thickening of the circular muscle may indicate the commencement of the pyloric antrum, true functional sphincteric activity distinct from the other peristaltic contractions of the stomach is not observed although some of these may in fact temporarily close off the antrum from the remainder of the stomach lumen. Synonym: antral sphincter, midgastric transverse sphincter, sphincter antri, sphincter intermedius, sphincter of antrum, sphincter of gastric antrum. (05 Mar 2000) |
| artificial sphincter | A sphincter produced by surgical procedures to reduce speed of flow in the digestive system or to maintain continence of the intestine. (05 Mar 2000) |
| basal sphincter | The thickening of the circular muscular coat at the base of the ileal papilla at the terminal ileum. Synonym: sphincteroid tract of ileum. (05 Mar 2000) |
| bicanalicular sphincter | A sphincter encircling two canals, such as the terminal portions of the common bile duct and the main pancreatic duct. (05 Mar 2000) |
