Male

Question 1

Spermatogenesis (def)

Answer 1

Process of producing sperm with half the number of chromosomes (haploid) as somatic cells

Question 2

Spermatozoa

Answer 2

Mature sperm

Question 3

Location of spermatogenesis

Answer 3

Seminiferous tubules (part of the male testes)

Question 4

Spermatogonia location

Answer 4

Line basement membrane of seminiferous tubule

Question 5

3 parts of spermatogenesis

Answer 5

Spermatocytogenesis(mitosis)-proliferation phase

Spermatogenesis (meiosis)- production of haploid gamete

Spermiogenesis - spermatids mature into spermatozoa

Question 6

Overall result of spermatogenesis

Answer 6

(Cell proliferation)-
Each spermatogonia may produce 256 spermatozoa per cycle

(Maintenance of a reserve germ cell population) production of spermatogonia is faster than maturation of spermatozoa

Haploid gametes are produced
Genetic variability

Question 7

Problems that may occur

Answer 7

Non-disjunction
Two headed sperm
Sperm with no acrosome
Oligospermia
Azoispermia

Question 8

GnRH

Answer 8

Released by hypothalamus triggers release of FSH and LH

Question 9

FSH (boys)

Answer 9

Released by anterior pituitary

Regulates mitotic division of spermatogonia

Increases spermatozoa numbers

Question 10

LH

Answer 10

Released by anterior pituitary

Increases testosterone production

Question 11

Testosterone

Answer 11

Released by leyding cells in S.T (testes)

Promotes Sertoli cell function
Continues spermatogenesis after production of sertoli
