what are the two functions of testes? |
sperm production, secretes testosterone |
|
|
1st step of producing sperm: |
spermatogenisis |
|
|
2nd step of sperm production: |
spermiogenesis |
|
|
spermatogenisis involves a diploid cell; |
spermatogonium |
|
|
spermatogonium undergoes meiosis to produce haploid gametes called; |
spermatids |
|
|
spermiogenesis is the; |
physical change that converts a soermatid to a spermatozoan |
|
|
secreting testosterone is performed by _________ called _________ ? |
endocrine cells ; interstitial cells |
|
|
testosterone has multiple targets, including: |
assisting in the stimulation of Sertoli cells to promote spermatogenisis; stimulating bone & muscle growth; establishing & maintaining secondary sexual characteristics; maintaining libido; maturing and maintaining make accessory glands |
|
|
interstitial cell |
also called leydig cell; located in spaces between adjacent seminiferous tubules; endocrine cell that creates testosterone |
|
|
interstitial cell |
also called leydig cell; located in spaces between adjacent seminiferous tubules; endocrine cell that creates testosterone |
|
|
spermatogonium |
stem cell; constantly undergoes mitosis to maintain a relatively constant number |
|
|
sertoli cell |
also called "nurse cells"; adjacent Sertoli cells create a channel for developing spermatocytes; support and protect spermatocytes |
|
|
sertoli cell |
also called "nurse cells"; adjacent Sertoli cells create a channel for developing spermatocytes; support and protect spermatocytes |
|
|
primary spermatocyte |
a spermatogonium cell that has entered spermatogenesis; destined to become four sperm cells |
|
|
sertoli cell |
also called "nurse cells"; adjacent Sertoli cells create a channel for developing spermatocytes; support and protect spermatocytes |
|
|
primary spermatocyte |
a spermatogonium cell that has entered spermatogenesis; destined to become four sperm cells |
|
|
secondary spermatocytes |
cells that have completed meiosis 1 |
|
|
spermatids |
cells that have completed meiosis 2 & are ready to undergo spermiogenesis |
|
|
spermatozoa |
immature sperm cells that have completed spermiogenesis; now in lumen of seminiferous tubule; ready for transport to epididymis |
