The early stage of embronic development during which rapid mitotic cell divisions occur as the zygote trabels down the uterine (fallopian) tube is called ______.
- A.
The acrosomal reaction
- B.
Fertilization
- C.
Implantation
- D.
Cleavage
Correct Answer
D. CleavageExplanation
Cleavage is the early stage of embryonic development where rapid mitotic cell divisions occur as the zygote travels down the uterine (fallopian) tube. During cleavage, the zygote divides into smaller cells called blastomeres, which eventually form a solid ball of cells called a morula. Cleavage is an important process that allows for the rapid growth and division of cells, leading to the formation of an embryo. The other options, such as the acrosomal reaction, fertilization, and implantation, are not correct because they refer to different processes that occur at different stages of embryonic development.Rate this question:

Filtrate formed during glomerular filtration is captured by the ________.
- A.
Renal hilum
- B.
Renal column
- C.
Renal pyramid
- D.
Glomerular (Bowman's) capsule
Correct Answer
D. Glomerular (Bowman's) capsuleExplanation
The glomerular (Bowman's) capsule is responsible for capturing the filtrate formed during glomerular filtration. This capsule is a cup-like structure that surrounds the glomerulus, which is a network of capillaries in the kidney. As blood passes through the glomerulus, water, ions, and small molecules are filtered out into the capsule, forming the initial filtrate. This filtrate will then undergo further processing in the renal tubules to form urine. The other options, renal hilum, renal column, and renal pyramid, are not directly involved in the capture of the filtrate.Rate this question:

Failure of the testes to descend into the scrotum is a condition known as ______.
- A.
Phimosis
- B.
Cryptorchidism
- C.
Hermaphroditism
- D.
Orchiditis
Correct Answer
B. CryptorchidismExplanation
Cryptorchidism is the correct answer because it refers to the condition where the testes fail to descend into the scrotum. This condition can occur in newborns or young boys and may require medical intervention to correct. Phimosis refers to a condition where the foreskin of the penis is too tight, hermaphroditism is a condition where an individual has both male and female reproductive organs, and orchiditis is the inflammation of the testes.Rate this question:

Menopause, which ends childbirth ability, is considered to have occurred when a woman ______.
- A.
Misses two periods in a row
- B.
Has gone a year without menstruation
- C.
Misses her first period
- D.
Has had a hysterectomy
- E.
Turns 50
Correct Answer
B. Has gone a year without menstruationExplanation
Menopause is the natural process in a woman's life when her menstrual cycle stops permanently, indicating the end of her reproductive years. This is typically diagnosed when a woman has gone a year without menstruation, as it signifies that her ovaries are no longer releasing eggs. Missing two periods in a row or having a hysterectomy can be factors that contribute to menopause, but they alone do not confirm its occurrence. Turning 50 is also not a definitive indicator, as menopause can happen at different ages for each woman.Rate this question:

The fluid-filled sac surrounding the fetus is the ______.
- A.
Chorionic billi
- B.
Mesodern
- C.
Amnion
- D.
Pplacenta
- E.
Umbilical cord
Correct Answer
C. AmnionExplanation
The correct answer is amnion. The amnion is a fluid-filled sac that surrounds and protects the fetus during development. It acts as a cushion, providing a stable and protective environment for the growing fetus. The amnion also helps regulate the temperature and allows for movement and growth of the fetus.Rate this question:

The blood vessel directly feeding the glomerulus with blood from the cortical radiate artery is the _____.
- A.
Efferent arteriole
- B.
Peritubular capillary
- C.
Afferent arteriole
- D.
Renal vein
Correct Answer
C. Afferent arterioleExplanation
The blood vessel directly feeding the glomerulus with blood from the cortical radiate artery is the afferent arteriole. The afferent arteriole carries oxygenated blood from the cortical radiate artery into the glomerulus, where filtration of waste products and excess water occurs. This vessel plays a crucial role in maintaining proper blood flow and pressure within the glomerulus, allowing for efficient filtration in the kidneys.Rate this question:

What stiumulates the release of renin from the juxtaglomerular (JG) apparatus?
- A.
Low blood ptassium levels
- B.
High blood pressure
- C.
High blood volume
- D.
Low blood pressure
- E.
High blood sodium levels
Correct Answer
D. Low blood pressureExplanation
Low blood pressure stimulates the release of renin from the juxtaglomerular (JG) apparatus. Renin is an enzyme released by the JG cells in response to low blood pressure. Its release is part of the renin-angiotensin-aldosterone system, which helps regulate blood pressure and fluid balance in the body. When blood pressure is low, the JG cells sense this and release renin, which then initiates a series of reactions leading to the production of angiotensin II, a potent vasoconstrictor that helps raise blood pressure.Rate this question:

On which day of the female's uterine (menstural) cycle does ovulation typically occur?
- A.
Day 7
- B.
Day 21
- C.
Day 14
- D.
Day 24
- E.
Day 28
Correct Answer
C. Day 14Explanation
Ovulation typically occurs on day 14 of the female's uterine (menstrual) cycle. This is because ovulation usually happens around the middle of the menstrual cycle, which is typically 28 days long. Ovulation is the release of an egg from the ovary, and it is a crucial step in the reproductive process as it allows for fertilization and pregnancy to occur.Rate this question:

The process by which a mature egg is ejected from the ovary is called ______.
- A.
Ovulation
- B.
Emission
- C.
Parturition
- D.
Fertilization
- E.
Menses
Correct Answer
A. OvulationExplanation
Ovulation is the correct answer because it refers to the process in which a mature egg is released from the ovary. This typically occurs once a month in females of reproductive age, and it is an essential step in the reproductive cycle. Ovulation is necessary for fertilization to occur, as it allows the egg to be available for fertilization by sperm.Rate this question:
-

Fertilization usually occurs in the _____.
- A.
Vagina
- B.
Uterus
- C.
Uterine (fallopian) tubes
- D.
Ovary
- E.
Vesicular (Graafian) follicle
Correct Answer
C. Uterine (fallopian) tubesExplanation
Fertilization usually occurs in the uterine (fallopian) tubes. These tubes are responsible for transporting the egg from the ovary to the uterus. During ovulation, an egg is released from the ovary and travels through the fallopian tube. If sperm is present in the fallopian tube, fertilization can occur. The fertilized egg then continues its journey to the uterus where it implants and develops into a pregnancy. The vagina, uterus, ovary, and vesicular (Graafian) follicle are all involved in the reproductive process, but fertilization specifically occurs in the fallopian tubes.Rate this question:

The functional unit of the kidney that filters blood and forms urine is the ______.
- A.
Renal pelvis
- B.
Glomerulus
- C.
Nephron
- D.
Renal pyramid
Correct Answer
C. NephronExplanation
The nephron is the functional unit of the kidney responsible for filtering blood and forming urine. It is composed of a glomerulus, which filters waste products and excess water from the blood, and a renal tubule, which reabsorbs necessary substances back into the bloodstream and excretes waste products as urine. The renal pelvis is a part of the kidney that collects urine before it is transported to the bladder. The renal pyramid is a structure in the kidney that contains the nephrons. However, only the nephron performs the specific function of filtering blood and forming urine.Rate this question:

From fertilization to week 8 of pregnancy, the conceptus is called ________.
- A.
A baby
- B.
A morula
- C.
A fetus
- D.
An embryo
- E.
A zygote
Correct Answer
D. An embryoExplanation
From fertilization to week 8 of pregnancy, the conceptus is called an embryo. During this period, the fertilized egg undergoes rapid cell division and begins to develop various organs and body structures. The term "embryo" is used to describe this early stage of development before the fetus stage begins.Rate this question:
