Front 2

This hormone stimulates the development of eggs and sperm.

Back 2

FSH

Front 3

This hormone stimulates and maintains metabolic processes and plays a role in development.

This hormone opposes the action ofparathyroid hormone.

Back 5

Calcitonin

Front 6

Click on the gland whose hormones provide long-term responses to stress.

Back 6

Adrenal gland with glucocorticoids and mineraocorticoids

Front 7

This hormone raises blood calcium level.

Back 7

Front 11

Which part of the male reproductive tract stores sperm as they mature until they exit from the male's body? 

Back 11

epididymis

Front 12

At what point does the secondary oocyte complete meiosis? 

Back 12

after species-specific proteins of sperm and ovum combine

Front 13

How do egg cells enter the oviduct after ovulation?

Back 13

Ciliary currents bring fluid inside, carrying the egg cell along.

Front 14

Into which structure is a human oocyte released upon ovulation

Back 14

abdominal cavity

Front 15

What is the source of the hormones that, when suddenly absent, are directly responsible for the onset of menstruation? 

Back 15

corpus luteum

Front 16

Sperm has several components; the function of the acrosome is to 

Back 16

release an enzyme that breaks down the membrane of the ovum

Front 17

Menstruation results in the discharge of

Back 17

the endometrial lining

Front 18

Because the genetic composition of the fetus is not identical to that of the mother, it is somewhat surprising that the fetus is not rejected as a foreign body. It appears that this is because

Back 18

a protective layer, the trophoblast, surrounds the embryo and prevents direct contact with maternal tissue

Front 19

Birth control pills contain synthetic estrogen and progesterone. How do these hormones prevent pregnancy?

Back 19

They keep the pituitary from secreting FSH and LH, preventing ovulation.
