neuroepithelium

 [noor″o-ep″ĭ-the´le-um]
1. epithelium made up of cells specialized to serve as sensory cells for reception of external stimuli. Called also sense or sensory epithelium.
2. the ectodermal epithelium, from which the central nervous system develops.

neu·ro·ep·i·the·li·um

(nū'rō-ep'i-thē'lē-ūm),
Epithelial cells specialized for the reception of external stimuli. Most neuroepithelial cells, notably the hair cells of the inner ear and the receptor cells of the taste buds, are not true neurons but transducer cells that stand in synaptic contact with the peripheral endings of sensory ganglion cells. The neuroepithelial receptor cells of the olfactory epithelium, by contrast, are true peripheral neurons with extremely thin, unmyelinated axons that compose the olfactory filaments that enter the olfactory bulb of the cerebral hemisphere. The NA also applies the term to the rods and cones of the retina.

Grade 1 is given to neoplasms with some immaturity, but with neuroepithelium absent or limited to a rare, low-power magnification (X 40) field within the tumor, and not more than 1 such focus in any slide.
7) The neural crest also forms from neuroepithelium by an epithelial-to-mesenchymal conversion process, but in contrast to the evolution of mesoderm, NCAD is down-regulated as the neural crest cells migrate from the neuroepithelial layer.
Following absorption of the drops through the round window membrane, gentamicin has to travel from the basal turn of the cochlea and through all its turns before it reaches the neuroepithelium of the otolithic organs and the semicircular canals in the vestibule where it does its damage.
Detected at GD17 in CB neuroepithelium, decreasing thereafter, similar in SC (b); developmentally regulated splice variant' [Na.
Sensory disorders are the result of a direct injury or damage to the olfactory neuroepithelium.
First, VPA accumulates in the neuroepithelium (Dencker et al.

In the developing rat brain, substantial increases in catecholamine levels, enzyme activity, and synaptogenesis have been noted on GD18 (39); by GD19, differentiated neurons of the ventral tegmental area and nucleus accumbens have increased at the expense of the neuroepithelium (40-42).
