Spermatogenisis phases
|
1. spermatigonial phase
2. spermatocyte phase 3. spermatid phase |
|
|
what occurs in 1st phase of spermatogenesis? simple explanation
|
spermatigonial phase
spermatigonia differentiate into primary spermatocytes |
|
|
complex process of spermatogonia phase
|
Dark type A cells differentiate into commited Pale type A cells
Pale type A differentiate into Type B cell Type B cell becomes primary spermatocyte |
|
|
what happens in spermatocyte phase?
|
primary spermatocyte replicates DNA prior to meiosis
now has 4n goes through mitosis 2x result 4 haploid (1n) spermatids |
|
|
can you see secondary spermatocyte in section?

|
What is the golgi phase?
|
acrosomal vessicle formation
|
|
|
what is the cap phase?
|
acrosome spreads and forms cap
|
|
|
What is the acrosomal phase
|
sperm reorients itself to bury head in sertoli cell
