1) A 25-year-old woman is trying to conceive and is monitored for her ovarian cycle. She
reports a surge in luteinizing hormone (LH) and subsequently ovulates. If fertilization
does not occur, which hormone primarily prevents the further development of ovarian
follicles?
1. Testosterone
2. Inhibin *
3. Gonadotropin-releasing hormone (GnRH)
4. Estrogen
2)During a fertility evaluation, a couple is informed that the male partner has a low sperm
count. An examination reveals that his Sertoli cells are functioning normally. Which
hormone is likely contributing to the negative feedback mechanism regulating his sperm
production?
1. Luteinizing hormone (LH)
2. Dihydrotestosterone (DHT)
3. Inhibin *
4. Estrogen
3)A pregnant woman in her first trimester presents with nausea and fatigue. Blood tests
indicate high levels of human chorionic gonadotropin (hCG). What is the primary role of
hCG during early pregnancy?
1. To promote fetal development of the reproductive organs
2. To stimulate the growth of ovarian follicles
3. To maintain the corpus luteum and prevent its degeneration *
4. To initiate the release of progesterone from the placenta
4)What is the primary organ responsible for producing testosterone in males?
Testes
5)What distinguishes the movements of the large intestine from those of the small
intestine?
1. The movements in the large intestine are faster than those in the small intestine.
2. The large intestine primarily uses haustral contractions for mixing and moving contents. *
3. The large intestine lacks any form of muscular contractions.
4. The small intestine uses peristalsis exclusively for all movements.
6)In a clinical setting, what is the significance of increased goblet cell activity in the large
intestine?
1. It indicates a malfunction of the digestive system leading to nutrient absorption issues.
, 2. It is a sign of inflammation due to an infection in the small intestine.
3. It reduces mucus production, which is essential for digestion.
4. It helps to lubricate and protect the intestinal lining and aids in fecal formation. *
7)What role does the cecum play in the digestive process?
1. It acts as a reservoir for materials coming from the small intestine and begins the
process of fermentation. *
2. It plays a key role in absorbing water and electrolytes from undigested food before it
moves to the large intestine.
3. It stores bile produced by the liver for fat digestion.
4. It serves as the main site for enzymatic digestion of proteins.
8)What is the primary role of the juxtaglomerular apparatus in the kidney?
1. Production of erythropoietin
2. Regulation of blood pressure and filtration rate *
3. Filtration of blood and formation of urine in nephrons
4. Reabsorption of glucose and amino acids
9)What is the primary function of the Loop of Henle in the nephron?
1. To filter blood and produce glomerular filtrate
2. To secrete hormones that help regulate blood pressure and fluid balance in the body
3. To absorb glucose and amino acids from the urine
4. To create a medullary osmotic gradient that allows for concentration of urine *
10)Which hormone regulates water reabsorption primarily in the collecting ducts?
1. Atrial natriuretic peptide (ANP)
2. Antidiuretic hormone (ADH) *
3. Cortisol
4. Aldosterone
11)What is the primary role of neutrophils in the immune response?
1. They primarily produce antibodies to target specific pathogens.
2. They are aggressively antibacterial and phagocytize pathogens and debris. *
3. They serve as antigen-presenting cells to activate T cells.
4. They release histamine to promote inflammation and enhance blood flow.
12)Which statement correctly describes the process of hemostasis?
1. It involves a vascular spasm, formation of a platelet plug, and coagulation of blood. *
2. It refers exclusively to the production of red blood cells in the bone marrow.
