reproductive Flashcards
whats the function of seminiferous tubules
produce sperm cells
whats the function of interstitial cells
produce and secrete male sex hormones
whats the function of seminal vesicles
secretes alkaline fluid containing nutrients and prostaglandis
whats the function of prostate gland
secretes a milky fluid containing citrate and an enzyme that liquefies semen
whats the function of bulbourethral gland
secretes fluid that lubricates end of penis
whats the function of penis
conveys urine and semen to outside the body
whats the function of ductus deferens
conveys sperm cells to ejaculatory ducts
whats the function of epididymis
conveys sperm cells to ductus deferens
whats the function of scrotum
encloses, protects, and regulates temperature of the testes
whats spermatozoa
product of spermatogenesis
what is spermatid
23 chromosomes
tail not developed yet
whats sustenticular cells
supporting cell within seminiferous tube
primary spermatocyte
divide during meiosis I
spermatogonium
stem cell
what is capacitation
Weakening of the acrosomal membrane, conferring on the sperm the ability to fertilize an egg
first stage development of ovarian follicles
fetal ovary contains primordial follicles consisting of primary oocytes surrounded by flattened epithelial cells
second stage development of ovarian follicles
After puberty, during each monthly cycle, several follicles are stimulated to develop, forming primary follicles. These structures contain primary oocytes.
third stage development of ovarian follicles
As follicles develop each month, the follicular cell layers increase, and spaces form.
spaces join to form the antrum. These are now secondary follicles.
fourth stage development of ovarian follicles
A mature follicle will contain a secondary oocyte which has completed meiosis I and contains 23 chromosomes, each with two chromatids.
fifth stage development of ovarian follicles
The cell that is ovulated is a secondary oocyte, surrounded by its zona pellucida and corona radiata.
which glands within the mammary glands produce milk
alveolar
which structures support breast tissue
suspensory ligaments

The formation of sperms cells (spermatogenesis) occurs in the __________. The resultant cell matures into a sperm cell in the __________.
- seminiferous tubules
- epididymis
fill in the blank
The anterior pituitary gland releases two gonadotropins that target the testes. The hormone __________ promotes the development of cells that secrete testosterone, and __________ stimulates cells that will give rise to sperm cells.
- LH
- FSH
fill in the blank
Beginning at puberty, primary oocytes continue meiosis. The resulting cells are secondary oocytes (future egg cells) in which the original chromosome number is __________.
halved
fill in the blank
In erectile tissue, impulses from the __________ nervous system cause __________ of the arteries and subsequent __________ of the veins. Consequently, blood accumulates in the erectile tissue producing an erection.
- parasympathetic
- dilation
- constriction
What is the name of the process that results in the formation of the female gametes by meiosis?
oogenesis
functions of the reproductive system?
- To secrete hormones vital to maintain secondary sex characteristics
- To produce and nurture gametes containing 23 chromosomes
- To transport sex cells or gametes to sites of fertilization
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 following accessory glands of the reproductive system may be malfunctioning?
seminal vesicle
