Name the first haploid cells (with 23 chromosomes) produced during spermatogenesis

secondary spermatocyte

During sperm development, the process of meiosis 1 results in cells called

secondary spermatocytes

A patient presents with low semen volume. In addition, he has a decrease in sperm motility due to a decrease in nutrients that supply energy to power the flagella. Which of the phone accessory glance of the protective system may be malfunctioning?

seminal vesicle

Define synapsis

Pairing of homologous chromosomes

1N—>1N

Describe the chromosome number before and after the fist meiosis division (meiosis 1)

2N—-> 1N

During the female reproductive cycle, what triggers menstruation?

A decrease in blood levels of estrogens and progesterone

The anterior pituitary releases two gonadotropins that target the testes; ______ promotes the development of cells that secrete testosterone and _____ stimulates cells that will give rise to sperm cells

LH; FHS

Describe the fate of each spermatid.

It differentiates into a sperm cell.

What is the definition of capacitation?

Weakening of the acrosomal membrane, conferring on the sperm the ability to fertilize an egg.

What is the theca?

a capsule around a follicle

During spermatogenesis, a spermatogonium divided by mitosis to produce

a spermatogonium and a primary spermatocyte

Within the mammary glands, milk is produced by _____ glands.

alveolar

In the presence of the hormones ______ and testosterone, substentacular cells stimulate the spermatogenic cells to undergo spematogenesis, giving rise to sperm cells

follicle stimulating hormone (FSH)

Where does a corpus luteum form?

from a follicle that ovulated an oocyte

What disease is caused by the human papilloma virus?

genital warts

Name the cells surrounding an oocyte

granulosa cells

The corona radiate consists of

granulosa cells

Beginning at puberty, primary oocytes continue meiosis. The resulting cells are secondary oocytes (future egg cells) in which the original chromosomes number is

halved

When homologous chromosomes are paired up during the first meiotic division (meiosis 1), they may trade segments, forming new combinations of genetic material. What is this called?

homologous recombination

What cells produce androgens (including) testosterone?

interstitial cells of the testes

oogenesis

What is the process of egg formation called?

oogenesis

Although mammary glands in males and females are similar, the development of mammary glands is different in males and females. Why?

ovarian hormones stimulate development of mammary glands in females

In a nonpregnant female, what is the primary source of estrogens and progesterone?
