Rhabdomer

from Wikipedia, the free encyclopedia

A rhabdomer is a brush-like microvilli border on one side of the photoreceptor cell . The membrane of the microvilli contains the rhodopsin . In many insects (e.g. bees ) the rhabdomers have grown together to form a compact structure (closed rhabdom), whereby the microvilli of adjacent cells are often oriented at right angles to one another. The symmetrical structure of the rhabdomere is the basis for polarization vision . Flies ( Musca , Calliphora ) have open rhabdomers.
