| 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) |
| Chievitz' layer | In the developing retina of an embryo, a transitory zone between the inner and outer neuroblastic layer's that is devoid of nuclei. (05 Mar 2000) |
| periosteal layer of dura mater | See: dura mater of brain. (05 Mar 2000) |
| choriocapillary layer | The internal layer of the choroidea of the eye, composed of a very close capillary network. Synonym: lamina choroidocapillaris, choriocapillaris, entochoroidea, lamina choriocapillaris, membrana choriocapillaris, Ruysch's membrane. (05 Mar 2000) |
| chromatography, thin layer | Chromatography on thin layers of adsorbents rather than in columns. The adsorbent can be alumina, silica gel, silicates, charcoals, or cellulose. (12 Dec 1998) |
| Meynert's layer | Layer 3 of the cortex cerebri. Synonym: Meynert's layer. (05 Mar 2000) |
| rostral layer | A whitish line appearing on perfectly median sections of the brain as a thin bridge connecting the rostrum of the corpus callosum with the lamina terminalis; the rostral lamina contains no commissural fibres; instead, it corresponds to the line along which the pia mater reflects from the medial surface of one hemisphere to that of the other. Synonym: lamina rostralis, rostral layer, teniola corporis callosi. (05 Mar 2000) |
| circular layer of muscular coat | The inner, circular layer of the smooth muscle of the muscular coat. Nomina Anatomica lists circular layers of muscular coats (stratum circulare tunicae muscularis...) of the following: 1) colon (... Coli ); 2) rectum (... Recti ); 3) small intestine (... Intestini tenuis ); 4) stomach (... Gastrici ). Synonym: stratum circulare tunicae muscularis gastricae, stratum circulare tunicae. (05 Mar 2000) |
| circular layer of tympanic membrane | Circular fibres deep to the radiate layer of the membrane that are more abundant near the periphery; not present in the pars flaccida. Synonym: circular layer of tympanic membrane. (05 Mar 2000) |
| claustral layer | The layer of subcortical gray matter between the external capsule and the white matter of the insula or extreme capsule. (05 Mar 2000) |
| clear layer of epidermis | A layer of lightly staining corneocytes in the deepest level of the stratum corneum; found primarily in the thick epidermis of the palmar and plantar skin. Synonym: clear layer of epidermis. (05 Mar 2000) |
| Waldeyer's zonal layer | A longitudinal bundle of thin, unmyelinated and poorly myelinated fibres capping the apex of the posterior horn of the spinal gray matter, composed of posterior root fibres and short association fibres that interconnect neighboring segments of the posterior horn. Synonym: fasciculus dorsolateralis, tractus dorsolateralis, dorsolateral tract, fasciculus marginalis, Lissauer's bundle, Lissauer's column, Lissauer's fasciculus, Lissauer's marginal zone, Lissauer's tract, marginal fasciculus, Spitzka's marginal tract, Spitzka's marginal zone, Waldeyer's tract, Waldeyer's zonal layer.
