| zona pellucida | <cell biology, gynaecology> A translucent, elastic, noncellular layer surrounding the ovum of many mammals. (11 May 1997) |
| zona perforata | The perforations along the tympanic lip of the spiral lamina giving passage to the cochlear nerves. Synonym: habenulae perforata, zona perforata. (05 Mar 2000) |
| zona pupillaris | The central region of the anterior surface of the iris located between the collarette and the pupillary margin. Synonym: zona pupillaris. (05 Mar 2000) |
| zona radiata | The thickened cell membrane of the ovum in forms, such as certain amphibia, in which it appears radially striated under the light microscope; with the electron microscope the striations can be seen to be microvilli. Synonym: membrana striata, striated membrane, zona radiata. (05 Mar 2000) |
| zona reticularis | The inner zone of the adrenal cortex. This zone consists of an anastomosing network of cells which resemble those of the zona fasciculata except for the fact that they contain less lipid. The mitochondria are elongated and contain a mixture of tubular and flattened cristae. (12 Dec 1998) |
| zona serpiginosa | <virology> A reactivation of the same Herpes virus that is responsible for chicken pox. This results in a painful blistery red rash that is confined to one side of the body. The zoster rash affects one nerve distribution or dermatome. Facial rash can lead to optic nerve involvement with resultant blindness. Synonym: shingles. (06 Mar 1998) |
| zona striata | The thickened cell membrane of the ovum in forms, such as certain amphibia, in which it appears radially striated under the light microscope; with the electron microscope the striations can be seen to be microvilli. Synonym: membrana striata, striated membrane, zona radiata. (05 Mar 2000) |
| zona tecta | The inner third of the basilar membrane of the cochlear duct extending from the tympanic lip of the osseous spiral lamina to the outer pillar cell of the spiral organ (of Corti). Synonym: zona arcuata, zona tecta. (05 Mar 2000) |
| zona vasculosa | An area in the external acoustic meatus where a number of minute blood vessels enter from the mastoid bone. Synonym: spongy spot, zona vasculosa. (05 Mar 2000) |
| angulus oculi medialis | The angle formed by the union of the upper and lower eyelids medially. Synonym: angulus oculi medialis, angulus oculi nasalis, internal canthus, medial canthus. (05 Mar 2000) |
| arcus lumbocostalis medialis | <anatomy> One of Haller's arches; a tendinous thickening of the psoas fascia that extends from the body of the first lumbar vertebra to its transverse process on either side. A portion of the diaphragm arises from it. Synonym: ligamentum arcuatum mediale, arcus lumbocostalis medialis, medial lumbocostal arch. (05 Mar 2000) |
| arcus pedis longitudinalis pars medialis | Formed by the calcaneus, talus, navicular, three cuneiform bones, and the three medial metatarsals. Synonym: arcus pedis longitudinalis pars medialis. (05 Mar 2000) |
| arteria circumflexa femoris medialis | <anatomy, artery> Origin, profunda femoris; distribution, hip joint, muscles of thigh; anastomoses, inferior gluteal, superior gluteal, lateral circumflex femoral. Synonym: arteria circumflexa femoris medialis, medial circumflex artery of thigh, medial femoral circumflex artery. (05 Mar 2000) |
| arteria frontobasalis medialis | <anatomy, artery> The medial orbitofrontal branch, the first branch of the pericallosal artery; it supplies the medial half of the inferior surface of the frontal cortex. Synonym: arteria frontobasalis medialis, ramus orbitofrontalis medialis, orbital artery. (05 Mar 2000) |
