웹2024년 3월 30일 · Cell polarity refers to spatial differences in shape, structure, and function within a cell.Almost all cell types exhibit some form of polarity, which enables them to carry out specialized functions. Classical examples of polarized cells are described below, including epithelial cells with apical-basal polarity, neurons in which signals propagate in one … 웹2024년 2월 17일 · 1. Introduction. Tissues must be of the correct size and shape in order to carry out their normal function. The basement membrane (BM) is a special type of extracellular matrix that lines the basal side of epithelial and endothelial cells and is important for the form and function of the overlying tissues.

웹Frequency tuning within the inner ear is attributable in part to the geometry of the basilar membrane, which is wider and more flexible at the apical end and narrower and stiffer at the basal end. One feature of such a system is that regardless of where energy is supplied to it, movement always begins at the stiff end (i.e., the base), and then propagates to the more … 웹2024년 3월 29일 · Structure. The basilar membrane is a pseudo-resonant structure that, like the strings on an instrument, varies in width and stiffness. But unlike the parallel strings of a guitar, the basilar membrane is not a discrete set of resonant structures, but a single structure with varying width, stiffness, mass, damping, and duct dimensions along its length. holiday gifts from children
