T)endometrium
U)placenta

Accepted Answer

The seminiferous tubules are the site of spermatogenesis in the male reproductive system.

Answer: O
 The epididymis is where mature sperm are stored before ejaculation and it is also where they gain motility.

Answer: P
 The ovarian follicle is the structure in the ovary where oogenesis occurs, leading to the release of an oocyte for potential fertilization.

Answer: S
 Sertoli cells are the support cells within the seminiferous tubules that aid in spermatogenesis.

Answer: N
 The corpus luteum is a temporary endocrine structure that forms in the ovary after ovulation and produces hormones, including progesterone, to support early pregnancy if fertilization occurs.

Note: The other answer options are not related to the site of spermatogenesis.

Question 2

Indicate whether the following functions are attributable to estrogen or progesterone by using the answer code (options may be used more than once or not at all):
-inhibits uterine contractility
A)estrogen
B)progesterone
C)both estrogen and progesterone

Accepted Answer

Progesterone is responsible for inhibiting uterine contractility, as it helps to maintain the uterine lining and prevent premature contractions. Estrogen, on the other hand, promotes uterine growth and development.

Question 3

Indicate whether the following functions are attributable to estrogen or progesterone by using the answer code (options may be used more than once or not at all):
-induces endometrial secretory capacity
A)estrogen
B)progesterone
C)both estrogen and progesterone

Accepted Answer

The oviduct, also known as the fallopian tube, is where fertilization typically occurs as it is the pathway for the egg to travel from the ovary to the uterus.

Answer: J
 The head of the sperm contains the genetic material necessary for fertilization of the egg.

Answer: P
 The ovarian follicle is a small sac that contains an egg and ruptures during ovulation, releasing the egg for potential fertilization in the oviduct.

Answer: U
 The placenta is an organ that develops during pregnancy and provides essential nutrients and oxygen to the developing fetus while also removing waste.

Answer: T
 The endometrium is the lining of the uterus and thickens in preparation for potential implantation of a fertilized egg. If implantation does not occur, the endometrium sheds during menstruation.

Answer: B
 The acrosome is a structure at the head of the sperm that contains enzymes necessary for penetration of the egg during fertilization.

Answer: O
 The epididymis is a small, coiled tube located on the top and at the back of each testicle. It is where sperm mature and are stored before ejaculation.

Answer: D
 The seminal vesicles are glands that secrete fluids that mix with sperm and other fluids to create semen.

Answer: A
 Erection occurs when the penis becomes engorged with blood, allowing for sexual intercourse and potential fertilization.

Answer: N
 The corpus luteum is a structure that develops in the ovary after ovulation and secretes progesterone, a hormone necessary for maintaining a potential pregnancy.
