Q

what are the two muscles that contract in the scrotum and what is their function

A

cremaster - skeletal muscle bringing testes closer to the body to bring warmth

Q

how much % of sperm does the bulbourethral glands make

A

less than 1%

17
Q

what is the function of the penis

A

delivers semen to female reproductive system

18
Q

what are the two sections of the penis and what are their functions

A

corpus cavernosa - fulls with blood to help maintain erection

corpus spongiosum - keeps urethra open for ejaculation

19
Q

describe the process of cell division of spermatogenesis

A

spermatogonium (stem cell) produces some more stem cells, but also a primary spermatocyte.

primary spermatocyte replicate DNA and divides into two secondary spermatocytes (meiosis 1).

secondary spermatocyte divides in half to make four spermatids (meiosis 2).

spermiogenesis then occurs to change the shape of the spermatid, adding a head and tale to create the sperm

20
Q

what does the head of the sperm contain

A

nucleus with 23 chromosomes

21
Q

why is the head of the sperm covered with the acrosome

A

the enzymes help penetrate the egg for fertilisation

22
Q

where in the sperm body is the mitochondria

A

in the middle piece of the tail

23
Q

describe the pathway of sperm (7)

A

seminiferous tubules
epididymis
ductus deferens
ejaculatory duct
prostatic urethra
membranous urethra
spongy urethra

24
Q

what are the 6 hormones for regulation in the male reproductive system

A

gonadotrpoin releasing hormone
luteinising hormone
follicle stimulating hormone
testosterone
androgen binding hormone
inhibin

25
Q

what is the function of the gonadotropin releasing hormone

A

stimulates release of luteinising hormone and follicle stimulating hormone

from the hypothalamus

26
Q

what is the function of the luteinising hormone

A

stimulates secretion of testosterone from interstitial cells

from anterior pituitary

27
Q

what is the function of the follicle stimulating hormone

A

stimulates secretion of ABP from sustentacular cells

from anterior pituitary

28
Q

what is the function of testosterone

A

development of sex organs and secondary sex characteristics

from the interstitial cells in testes

29
Q

what is the function of the androgen binding proteins

A

binds to testosterone to keep concentration high for spermatogenesis

from the sustentacular cells in testes

30
Q

what is the function of inhibin

A

inhibits secretion of follicle stimulating hormone

from the sustentacular cells in testes
