Document Summary
Acb 3309 lecture 16 (38) male reproductive system male duct. Up to 300 lobules in the testis. Each tubule is a loop like structure both ends communicate with a meshwork of epithelial lined space: spermatozoa are being delivered and collected in this meshwork, since it is meshwork, name is rete (net) testis. Spermatozoa are being collected at the apical part of the testis, into several tubules. In humans, there are up to a dozen tubules = ductuli efferentes: ducts that carry out of the testes. Ductuli efferentes combine into one highly coiled tube, that has an elongated shape: lies along the testes, = epididymis. In the epididymis, there are structural and functional differences within different regions: head, long body, tail. Epididymis is a single coiled tube that merges as a muscular epithelial lined tube = vas deferens. Can make out these tubules: epididymis highly coiled, lies alongside of the testes, enveloped into ct.
