The Sustentacular Cells Form The -Testis Barrier. - Web sustentacular cells form a barrier on the apical surface of the oe, extend processes across the width of the epithelium to the basement membrane, and may function like glial cells in the brain to provide metabolic, structural, and trophic support for olfactory receptor neurons ( getchell and getchell 1992 ). We present data detailing their dynamic activity. Web sustentacular cells have structural features that allude to functions of secretion, absorption, phagocytosis, maintenance of extracellular ionic gradients, metabolism of noxious chemicals, and regulation of cell turnover. Web the epithelium consists of sertoli's sustentacular cells and the spermatogenic cells. Additionally, these cells help in the repair and regeneration of damaged nerves. With their labyrinthine cellular processes they surround the individual types of germ cells more or less completely. The ____________________ form a blood testes barrier that prevents sperm cells from coming in direct contact with blood. The ____________________ secrete testosterone and other androgens. Web the olfactory epithelium is composed of three basic cell types (sensory, sustentacular, and basal cells) (figure 30.3).the olfactory sensory cells (or receptor cells) are bipolar neurons interposed between the sustentacular cells.the dendritic portions of these neurons extend above the epithelial surface and terminate into a bulbous olfactory knob from which protrude 12 or more immotile cilia.
