| granular layer of a vesicular ovarian follicle | The layer of small cells that forms the wall of an ovarian follicle. Synonym: granular layer of a vesicular ovarian follicle, granulosa, membrana granulosa, stratum granulosum ovarii. (05 Mar 2000) |
|---|---|
| granular layer of cerebellar cortex | The deepest of the three layers of the cortex; it contains large numbers of granule cells, the dendrites of which synapse with incoming mossy fibres in cerebellar glomeruli. Thin, unmyelinated axons of granule cells ascend perpendicularly into the molecular layer in which they bifurcate into fibres coursing parallel to the long axis of the cerebellar folia. Parallel fibres form numerous synapses with the dendrites of Purkinje cells, basket cells, and stellate cells. Synonym: stratum granulosum cerebelli, granular layer of cerebellar cortex.

| granular layer of epidermis | A layer of somewhat flattened cells containing basophilic granules of keratohyalin and lying just above the stratum spinosum and deeply to the stratum corneum. Synonym: stratum granulosum epidermidis. (05 Mar 2000) |
| Tomes' granular layer | <dentistry> A thin layer of dentin adjacent to the cementum, appearing granular in ground sections; the granules are small uncalcified spaces. (05 Mar 2000) |
| bacterial outer membrane proteins | Proteins isolated from the outer membrane of bacteria. (12 Dec 1998) |
| rod outer segment | <ophthalmology, physiology> Major photoreceptor cell of vertebrate retina (about 125 million in a human eye). Columnar cells (about 40m long, 1m diameter) having three distinct regions: a region adjacent to and synapsed with, the neural layer of the retina contains the nucleus and other cytoplasmic organelles, below this is the inner segment, rich in mitochondria, that is connected through a thin neck (in which is located a ciliary body) to the outer segment. The outer segment largely consists of a stack of discs membrane infoldings that are incompletely separated in cones) that are continually replenished near the inner segment and that are shed from the distal end and phagocytosed by the pigmented epithelium. The membranes of the discs are rich in rhodopsin, the pigment that absorbs light. (03 Jul 1999) |
| rod outer segments | The portion of the retinal rod cell between the inner segment and the pigment epithelium layer of the retina. (12 Dec 1998) |
| hair cells, outer | Mechanoreceptors in the organ of corti. In mammals the outer hair cells are arranged in three rows which are further from the modiolus than the single row of inner hair cells. The motile properties of the outer hair cells may contribute actively to tuning the sensitivity and frequency selectivity of the cochlea. (12 Dec 1998) |
| outer cone fibre | Located between the inner segment and the cell body. (05 Mar 2000) |
| outer malleolus | The process at the lateral side of the lower end of the fibula, forming the projection of the lateral part of the ankle; the lateral malleolus is more inferiorly placed then the medial malleolus. Synonym: malleolus lateralis, external malleolus, extramalleolus, outer malleolus. (05 Mar 2000) |
| outer membrane | The larger of the two membranes of a double membrane. (05 Mar 2000) |
| outer table of skull | The outer compact layer of the cranial bones. Synonym: lamina externa cranii. (05 Mar 2000) |
| the outer | Ovarian extremity of the oviduct. (05 Mar 2000) |
| Paneth's granular cells | Cell's, located at the base of intestinal glands of the small intestine, which contain large acidophilic refractile granules and may produce lysozyme. Synonym: Davidoff's cells. (05 Mar 2000) |
