| order of sperm from seminiferous tubule to outside world? |
seminiferous tubule->rete testis->efferent ductules->epididymis->ductus deferens->urethra |
| rete testis is what epithelium? |
simple cuboidal (duct) |
| function of efferent ductules? |
resorbs fluid from semen |
| efferent ductules epithelium? interesting morphology? |
cuboidal/ciliated columnar; has circular layer of smooth muscle |
| what is the epithelium of the epididymis? |
pseudostratified columnar epithelium with stereocilia |
| what is epithelium of ductus deferens? interesting morphology? |
pseudostratified columnar epithelium; 3 layers of muscle |
