ANA300Y1 Lecture Notes - Lecture 34: Seminiferous Tubule, Sustentacular Cell, Pseudostratified Columnar Epithelium
Document Summary
Adluminal compartment refers to this space and all fluid here, basal compartment is everything below tight junction, surrounding interstitial fluid continuous with all the tissue fluid down there. Sustentacular cells can add things to the adluminal compartment using transporters to control composition basal compartment has nothing to do with cytoplasm of sustentacular cell. Two mechanisms help make fluid flow from seminiferous tubules to epididymis intratesticualr excretory ducts=tubuli recti, rete testes, ductuli efferentes after this, we are outsides testicle. Epididymis subdivided into head, body and a tail where it narrows this is one long tube, 10-20 efferent ductules empty into single long tube which is all curled up tail of epididymis ends by becoming the vas (ductus) deferens. Accessory glands 3 glands 2 are paired, one is not structure and function of these glands are testosterone dependent, they can"t produce without testosterone thus don"t before puperty. Seminal vesicles produce ~70% of volume of seminal fluid between base of bladder & rectum.
