Question 1

At the time of ovulation a(n)_________is extruded from a_________ follicle.

Accepted Answer

At the time of ovulation, a secondary oocyte is extruded from a vesicular (or Graafian) follicle. This is a key event in the female reproductive cycle, where the mature oocyte is released and becomes available for fertilization.

Question 2

This hormone promotes the enrichment of the blood supply and secretion of nutrients of the functional layer of the endometrium during the secretory phase of the menstrual cycle.

Accepted Answer

Progesterone is the hormone responsible for thickening the functional layer of the endometrium, promoting the growth of blood vessels, and secretion of nutrients during the secretory phase of the menstrual cycle. Estrogen promotes the initial thickening of the endometrium during the proliferative phase, while LH and FSH stimulate the production of estrogen and progesterone. However, only progesterone has the specific function of enriching the blood supply and nutrient secretion in the endometrium during the secretory phase.

Question 3

What physical properties of sperm make them particularly well suited for their job?

Accepted Answer

Sperm have tails (flagella) that enable them to swim and propel themselves forward towards the egg, which is essential for fertilization.

Question 4

Spermatogonia in the seminiferous tubules are located_________ .

Accepted Answer

Spermatogonia are located closest to the outer edge of the seminiferous tubules, where they undergo mitosis to produce more spermatogonia or begin the process of spermatogenesis.

Question 5

Steps seen in meiosis but not mitosis are_________ .

Accepted Answer

Meiosis includes unique steps such as synapsis (pairing of homologous chromosomes), crossover (exchange of genetic material between homologous chromosomes), and two divisions, where the second division does not involve chromosome replication. These processes are specific to meiosis and are not seen in mitosis, which is a single division process without these features.

Question 6

During the proliferative phase of the uterine cycle,_________ .

Accepted Answer

During the proliferative phase of the uterine cycle, the functional layer of the endometrium is rebuilt. This is the phase where the endometrium starts thickening and increasing in vascularity, preparing for a possible implantation of a fertilized egg. The blood supply and glandular secretion of nutrients in the endometrium continue to increase until ovulation occurs. The shedding of the functional layer of the endometrium occurs during the menstrual phase.

Question 7

The process of cellular division by which gametes are formed is called __________.

Accepted Answer

Meiosis is the type of cell division that reduces the number of chromosomes by half and results in the production of gametes (sperm and eggs in animals, pollen and ovules in plants).

Question 8

What happens at the end of the uterine cycle if fertilization has not occurred?

Accepted Answer

If fertilization does not occur, the corpus luteum, which is a temporary structure formed in the ovary after ovulation, degenerates. This leads to a decrease in progesterone and estrogen levels, contributing to the onset of menstruation.

Question 9

When sperm and egg fuse, a _________is formed.

Accepted Answer

A zygote is formed when a sperm and egg fuse, marking the beginning of a new organism's development.

Question 10

A primary oocyte residing in a primordial follicle becomes a secondary oocyte_________ .

Accepted Answer

A primary oocyte completes its first meiotic division to become a secondary oocyte in the vesicular (antral or Graafian) follicle stage, just before ovulation.
