Definition
| =LH; stimulates Leydig cells in males to secrete testosterone. |
|
|
Term
|
Definition
| secreted by sertoli cells in response to FSH in order for test. to bind in seminif. tubules |
|
|
Term
|
Definition
| produced by sertoli cells |
|
|
Term
|
Definition
| formed by sertoli cells to prevent antibodies from eating sperm via tight junctions. subdivides the basal from the adluminal region of the seminif tubule and separates spermatogonia from primary spermatocytes onwards to sperm |
|
|
Term
| if antibodies bind to head vs. tail of sperm |
|
Definition
| = bad binding w/ egg vs. bad motility |
|
|
Term
| key events in spermiogenesis (4) |
|
Definition
| growth of flagella from basal body MTOC, mitochondrial sheath forms around flagellum, acrosome forms = capping the nucleus, excess cytoplasm is shed and phagocytosed by sertoli cell |
