Question 1

What is the function of gonads?

Answer 1

 produce gametes (sex cells): Sperm—male gametes, Ova (eggs)—female gametes
 secrete hormones

Question 2

What is the role of the seminiferous tubules?

Answer 2

Production of sperms

Question 3

How are nonmotile spermatids converted to functional sperm?

Answer 3

Excess cytoplasm is discarded and what remains is compacted into the head, midpiece, and tail regions. Final maturation processes in the epididymis result in increased motility.

Question 4

What name is given to an ovarian follicle that is ready or nearly ready to ovulate?

Answer 4

Vesicular (Graafian) follicle

Question 5

Which anterior pituitary hormone causes ovulation?

Answer 5

LH

Question 6

What are three important functions of progesterone in women?

Answer 6

1. Cause the secretory phase of the menstrual cycle
2. Helps prepare the breasts for lactation
3. Helps quiet uterine muscle to maintain pregnancy

Answer 8

Epididymis

Question 9

What are the male accessory glands?

Answer 9

Seminal vesicles, prostate, bulbourethral glands

Question 10

Answer 13

Ovarian follicles

Question 14

Estrogen are produced by —— in response to —.

Answer 14

Question 15

The menstrual cycle involves changes in the endometrium in response to fluctuating blood level of ovarian hormones.
There are three phases:
