Germ Layers definition: The three primary germinal layers (ECTODERM; ENDODERM; and MESODERM) developed during GASTRULATION that provide tissues and body plan of a mature organism. They derive from two early layers, hypoblast and epiblast.
germ layer definition: one of the three layers of primodial cells comprising the early embryo, formed during gastrulation.
Smear Layer definition: Adherent debris produced when cutting the enamel or dentin in cavity preparation. It is about 1 micron thick and its composition reflects the underlying dentin, although different quantities and qualities of smear layer can be produced by the various instrumentation techniques. Its function is presumed to be protective, as it lowers dentin permeability. However, it masks the underlying dentin and interferes with attempts to bond dental material to the dentin.
Muscularis Propria definition: The detrusor muscle of the bladder, forming the muscular wall of the bladder, consisting of the inner longitudinal; middle circular; and outer longitudinal layers.
Muscle Layer definition: The smooth muscle component of an organ, especially of a hollow organ or tubular structure.
Episclera definition: A thin fibrous membrane that covers the outer surface of the anteriors sclera and contains blood vessels which supply the sclera.
Bowman's Membrane definition: A transparent homogeneous acellular layer, 6 to 9 um thick, lying between the basal lamina of the outer layer of stratified epithelium and the substantia propria of the cornea; it is considered to be a basement membrane.
Bowman Membrane definition: A layer of acellular matrix that lies beneath the CORNEAL EPITHELIUM and above the CORNEAL STROMA. It consists of randomly arranged COLLAGEN fibers in a condensed bed of intercellular substance. It provides stability and strength to the cornea.
Retina Layer definition: The tissue that constitutes the retina. It is composed of the following layers: ganglion cell layer, inner limiting membrane, inner nuclear layer, inner plexiform layer, layer of the ophthalmic nerve fibers, layer of the rods and cones, neural retina, outer limiting membrane, outer nuclear layer, outer plexiform layer, and retinal pigment epithelium.
Layer definition: A relatively thin sheetlike expanse or region lying over or under another.
S-layer definition: A crystalline protein layer surrounding some bacteria. [GOC:mlg, ISBN:0815108893]
murein sacculus definition: OBSOLETE. A peptidoglycan polymer that forms the shape-determining structure of the cell all of Gram-negative bacteria. [GOC:ma]
peptidoglycan layer definition: OBSOLETE. A structure formed of the cross-linked polymer peptidoglycan (also called murein) that forms a covalently closed net around a bacterial cell, and imparts structural stability to the bacterial cell wall. [GOC:mah, PMID:9529891]
Ganglionic Layer of the Cerebral Cortex definition: The fifth layer of the cerebral cortex, composed of the largest pyramidal cells (Martinotti's cells and Betz's cells), and traversed by a layer of horizontally arranged fibers.
Coat definition: A thin outer layer or film covering something.
Layer definition: Chickens raised for egg production
foot layer definition: The inner layer of the ectexine. [http://www.mobot.org/MOBOT/research/APweb/]
hyaline layer definition: A multilayered extraembryonic matrix that functions as a substrate for cell adhesion through early development. It is thought to protect and lubricate the embryo, stabilize the blastomeres during morphogenesis, and regulate nutrient intake. The major constituent of the hyaline layer is the protein hyalin. This matrix has been found in echinoderms. [http://worms.zoology.wisc.edu/urchins/SUgast_ECM3.html, PMID:1721506, PMID:9473317]
