| e-layer | <radiobiology> Cylinder of relativistic electrons gyrating in a magnetic field, which produces a self-field strong enough to dominate the externally applied field and produce a field-reversal (where the B field changes sign) in the system. See: Field-Reversed Configuration, Field-Reversed Pinch. (09 Oct 1997) |
|---|---|
| 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) |
| enamel layer | The internal layer of the enamel organ. Synonym: enamel layer. (05 Mar 2000) |
| ependymal layer | An inner epithelial layer of cells bordering the lumen of the embryonic neural tube and brain, formed during the latter's stratification, and persisting in modified form throughout life. Synonym: ependymal zone, ventricular layer. (05 Mar 2000) |
| epithelial choroid layer | The layer of modified ependymal cells that forms the inner layer of the tela choroidea, facing the ventricle. Synonym: lamina epithelialis, epithelial choroid layer, lamina choroidea epithelialis, lamina choroidea. (05 Mar 2000) |
| epitrichial layer | The superficial flattened-cell layer of the epidermis of a young embryo before the definitive stratification has developed. (05 Mar 2000) |
| external nuclear layer of retina | The outermost layer of the cerebral layer of retina, composed of the primary receptor cells of the retina; the stratum consists of two sublayers: 1) an external layer made up of the rods and cones, the photosensitive processes of the receptor cells, and 2) the external nuclear layer containing the cell bodies of these cells; the external limiting membrane forms a perforated supporting plate between the two sublayers; the name refers to the fact that the retinal receptor cells are a specialised form of (epithelial) ependyma cell and thus, in a sense, are comparable to the neuroepithelial cells (e.g., hair cells) of other sense organs. Synonym: external nuclear layer of retina, stratum neuroepitheliale retinae, stratum nucleare externum retinae. (05 Mar 2000) |
| fatty layer of superficial fascia | The more superficial, fatty part of the superficial fascia of the lower anterior abdominal wall. Synonym: fatty layer of superficial fascia. (05 Mar 2000) |
| feeder layer | <cell culture> In order to culture some cells, particularly at low or clonal density, it is necessary to use a layer of less fastidious cells to condition the medium. Often the cells of the feeder layer are irradiated or otherwise treated so that they will not proliferate. In some cases the feeder layer may be producing growth factors or cytokines. (18 Nov 1997) |
| zonular layer | A thin layer of white substance covering the upper surface of the thalamus and forming part of the floor of the body of the lateral ventricle, a layer of white substance on the surface of the superior colliculus. Synonym: stratum zonale. (05 Mar 2000) |
| Kolliker's layer | The layer of connective tissue in the iris. (05 Mar 2000) |
| fibrous layer | The outer dense connective tissue layer of the periosteum. (05 Mar 2000) |
| fillet layer | A largely fibrous (hence whitish) layer of the superior colliculus separating the middle gray layer of superior colliculus from the deep gray layer of superior colliculus and containing, among others, fibres from the spinal and trigeminal lemnisci. Synonym: fillet layer. (05 Mar 2000) |
| Langhans' layer | The inner layer of the trophoblast. Synonym: Langhans' layer. (05 Mar 2000) |
| lateral cartilaginous layer | The narrow lateral portion of the cartilaginous part of the auditory tube. Synonym: lamina lateralis cartilaginis tubae auditivae, lamina cartilaginis lateralis tubae auditivae, lateral cartilaginous layer, lateral layer of cartilaginous auditory tube. (05 Mar 2000) |
