Question 1

The ________ is the inner membranous sac surrounding the fetus.
A)amnion
B)placenta
C)endometrium
D)chorion

Accepted Answer

The amnion is the innermost layer of the fetal membrane that surrounds the developing fetus and contains the amniotic fluid. The placenta is an organ that develops during pregnancy to provide nutrients and oxygen to the developing fetus. The endometrium is the lining of the uterus that thickens during the menstrual cycle and sheds during menstruation. The chorion is the outermost fetal membrane that helps form the placenta.

Question 2

The male reproductive system and the urinary system share which organ?
A)urethra
B)ureter
C)bladder
D)prostate gland

Accepted Answer

The urethra is a tube that both the male reproductive system and urinary system use to eliminate waste and fluids from the body.

Question 3

The pigmented area around the nipple of the breast is called the:
A)lactiferous duct.
B)lactiferous gland.
C)areola.
D)mammary gland.

Accepted Answer

The pigmented area around the nipple of the breast is called the areola. A is incorrect as the lactiferous duct transports milk from the lactiferous gland to the nipple. B is incorrect as the lactiferous gland is the milk-producing gland of the breast. D is incorrect as the mammary gland is another name for the lactiferous gland.

Question 4

Until the end of the eighth week of gestation,the infant is called a(n):
A)neonate.
B)embryo.
C)zygote.
D)fetus.

Accepted Answer

Until the end of the eighth week of gestation, the developing human is called an embryo, not a neonate or fetus. A zygote only exists for a short period after fertilization.

Question 5

The vas deferens connects:
A)epididymis to bladder.
B)epididymis to urethra.
C)testes to penis.
D)testes to urethra.

Accepted Answer

The vas deferens is a muscular tube that connects the epididymis, where sperm mature and are stored, to the ejaculatory ducts, which empty into the urethra inside the prostate gland. Thus, it connects the epididymis to the urethra, allowing sperm to be expelled from the body during ejaculation.

Question 6

Which of the following choices would NOT be a function of the secretions of the male reproductive glands?
A)activate sperm
B)nourish sperm
C)neutralize acidic pH
D)lubrication

Accepted Answer

Activating sperm is not a function of the secretions of the male reproductive glands; rather, these secretions primarily nourish sperm, neutralize the acidic pH of the female reproductive tract, and provide lubrication.

Question 7

The male reproductive system has pairs of the following organs EXCEPT the:
A)vas deferens.
B)prostate gland.
C)epididymis.
D)seminal vesicle.

Accepted Answer

The prostate gland is not paired like the other organs listed. It is a single gland located below the bladder in males.

Question 8

A premature infant is born prior to the completion of ________ weeks of gestation.
A)37
B)25
C)38
D)40

Accepted Answer

A premature infant is defined as one born before the completion of 37 weeks of gestation.

Question 9

Which of the following is NOT one of the male reproductive glands?
A)bulbourethral
B)prostate
C)seminal vesicle
D)cystic

Accepted Answer

There is no gland in the male reproductive system called the "cystic gland." The other options mentioned (bulbourethral gland, prostate gland, and seminal vesicle) are all male reproductive glands.

Question 10

The first stage of labor and delivery is called the ________ stage.
A)expulsion
B)dilation
C)effacement
D)placental

Accepted Answer

The first stage of labor and delivery is characterized by the dilation (widening) and effacement (thinning) of the cervix. This stage can last for several hours or even days, and includes early labor, active labor, and transition. The expulsion stage refers to the second stage of labor when the baby is actually born, and the placental stage refers to the third stage when the placenta is delivered.

Question 11

The expulsion stage of labor and delivery ends with:
A)delivery of placenta.
B)full dilation of cervix.
C)delivery of infant.
D)effacement.

Accepted Answer

The expulsion stage of labor and delivery ends with the delivery of the infant. This stage begins after the cervix is fully dilated and continues until the baby is born.

Question 12

A common time for congenital anomalies to occur is:
A)immediately following childbirth.
B)in the last trimester of pregnancy.
C)in early childhood.
D)during the embryo stage.

Accepted Answer

Congenital anomalies refer to physical or functional abnormalities that are present at birth. These anomalies occur during development in the womb, particularly during the embryonic stage. Therefore, the best choice is D: during the embryo stage. Anomalies will not occur immediately following childbirth, in the last trimester of pregnancy, or in early childhood, as these periods are after the critical period of development in the womb.

Question 13

Which structure is NOT part of the spermatic cord?
A)nerves
B)arteries
C)urethra
D)vas deferens

Accepted Answer

The urethra is not part of the spermatic cord, which is a bundle of structures that pass through the inguinal canal from the abdominal cavity to the testes. The nerves, arteries, and vas deferens are all part of the spermatic cord.

Question 14

The tip of the penis is called the:
A)prepuce.
B)glans penis.
C)shaft of the penis.
D)penile gland.

Accepted Answer

The tip of the penis is referred to as the glans penis. The prepuce is the fold of skin that covers the glans penis in uncircumcised males. The shaft of the penis is the long cylindrical part of the penis, and penile gland is not a term commonly used to refer to any part of the penis.

Question 15

Spermatogenesis occurs in the:
A)seminal vesicle.
B)prostate gland.
C)seminiferous tubules.
D)epididymis.

Accepted Answer

Spermatogenesis, the process of sperm production, takes place in the seminiferous tubules of the testicles. The seminal vesicle and prostate gland contribute to the production of semen, while the epididymis is where sperm are stored and matured.

Question 16

The testes are located in the scrotum:
A)for proper alignment of the spermatic cord.
B)for proper testosterone production.
C)for protection.
D)because spermatogenesis requires a lower temperature.

Accepted Answer

The testes are located in the scrotum because spermatogenesis, the process of sperm production, requires a slightly lower temperature than the body's internal temperature. The scrotum provides a cooler environment for the testes, which supports proper sperm development.

Question 17

After spermatogenesis,sperm are stored in the:
A)epididymis.
B)vas deferens.
C)urethra.
D)seminal vesicle.

Accepted Answer

After spermatogenesis, sperm are stored in the epididymis. The epididymis is a small, coiled tube connected to the testicle, where sperm mature and are stored until ejaculation. The vas deferens is a tube that carries sperm from the epididymis to the urethra during ejaculation, while the urethra is a tube that carries urine and semen out of the body. The seminal vesicle is a gland that produces fluids that combine with sperm to form semen. However, none of these structures store sperm after spermatogenesis.

Question 18

Which of the following is the longest period of gestation in which organs grow and mature?
A)umbilical
B)uterine
C)fetal
D)embryonic

Accepted Answer

Fetal period is the longest period of gestation (from 9 weeks after fertilization until birth) during which organs grow and mature, and the fetus gains weight and length. The umbilical period refers to the time when the fetus is connected to the placenta via the umbilical cord, which is a part of the fetal period. The uterine period refers to the time when the fertilized egg implants in the uterus, but it is not a period of gestation. The embryonic period refers to the time from fertilization until the end of the 8th week of gestation when the major organs and structures start to form.

Question 19

The length of typical human gestation is:
A)42 weeks.
B)30 weeks.
C)36 weeks.
D)40 weeks.

Accepted Answer

The typical human gestation period is approximately 40 weeks, or 280 days, from the first day of the woman's last menstrual period to the delivery of the baby.

Question 20

The umbilical cord connects the fetus to the:
A)amnion.
B)chorion.
C)endometrium.
D)placenta.

Accepted Answer

The umbilical cord connects the fetus to the placenta, which is responsible for nutrient and gas exchange between the fetus and the mother's blood supply.
