1
Q

Spermatogonia

A
  1. Stem cells
  2. Divide by mitosis to produce two daughter cells.
  3. One daughter cell remains at that location as a spermatogonium
  4. The other cell differentiate into a primary spermatocyte
2
Q

Meiosis

A

A specialized form of cell division involved only in the production of gametes

3
Q

Primary spermatocytes

A
  1. Are the cells that begin meiosis

2. Give rise to secondary spermatocytes

4
Q

Secondary spermatocytes divide and differentiate into spermatids

A

Spermatids are immature gametes that differentiate into spermatozoa.
Spermatozoa enter fluid in the lumen.

5
Q

Nurse cells

A

Aka sustentacular cells
Or
Sertoli cells
Provide a microenvironment that supports spermatogenesis

6
Q

All stages of meiosis are seen in the

A

Seminiferous tubules

7
Q

The complete process takes — days. Involves – processes called?

A
64
3
Mitosis 
Meiosis 
Spermiogenesis
8
Q

Mitosis

A
  1. Spermatogonia are stem cells that undergo division
  2. One daughter cell remains in place
  3. Other cell becomes primary spermatocyte
9
Q

Meiosis

A
  1. Cell division involving gamete production.
  2. Human gametes have 23 chromosomes
  3. Produces spermatids- the undifferentiated male gametes
10
Q

Spermatogenesis

A

Spermatids become physically mature spermatozoa- highly specialized cells
