38
Q

Seminiferous tubules

A

Where sperm is being produced

39
Q

Epididymis

A

A coiled tube next to each testis and receives sperm from the seminiferous tubules

40
Q

Three phases of spermatogenesis

A

Spermatocytogenesis
Diploid cell meiosis
Spermiogenesis

41
Q

Spermatocytogensis

A

Immature spermatogonia undergo mitotic division

*where mitosis takes place

42
Q

Diploid cells -Meiosis

A

Diploid number present in first phase becomes haploid, 23 chromosomes

*secondary spermatocytes (haploid spermatids)

43
Q

Spermiogenesis

A

Spermatids undergo morphological changes

*final phase-spermatids are haploid, see acrosome form & elongated

44
Q

Spermiogenesis

A

Midpiece - mitochondria

Acrosome - enzymatic knife used to penetrate the oocyte

Nucleus - haploid chromosomes

45
Q
