1. Which of the following is NOT a function of the nervous system?
- A. Detecting touch
- B. Regulating body temperature
- C. Producing insulin
- D. Controlling muscle movement
Correct answer: C
Rationale: The nervous system is responsible for detecting touch (option A), regulating body temperature (option B), and controlling muscle movement (option D). Producing insulin (option C) is a function of the endocrine system, which produces hormones like insulin to regulate metabolism and glucose levels. Therefore, option C is the correct answer as it is not a function of the nervous system.
2. Which of the following scenarios represents an example of static friction?
- A. Sliding a heavy box across the floor
- B. A car moving around a curve
- C. Pushing a stationary object
- D. Braking a car to stop
Correct answer: C
Rationale: The correct answer is C. Static friction occurs when two surfaces are in contact but not moving relative to each other. Pushing a stationary object involves static friction as you apply a force to overcome the friction keeping the object stationary. Choices A, B, and D involve kinetic friction, which occurs when two surfaces are moving relative to each other. Option A involves moving the box across the floor, which is an example of kinetic friction. Option B involves the movement of a car around a curve, which also relates to kinetic friction due to the relative movement between the tires and the road. Option D describes braking a car to stop, where the moving car's wheels interact with the road, creating kinetic friction to slow down and stop the car.
3. What is the microscopic functional unit of the kidney responsible for filtering blood?
- A. Ureter
- B. Nephron
- C. Renal pelvis
- D. Bladder
Correct answer: B
Rationale: The nephron is the correct answer as it is the microscopic functional unit of the kidney responsible for filtering blood. It is composed of a renal corpuscle (glomerulus and Bowman's capsule) and a renal tubule. The other options, such as (A) Ureter, (C) Renal pelvis, and (D) Bladder, do not play a role in filtering blood within the kidney. The ureter is a tube that carries urine from the kidney to the bladder. The renal pelvis is a part of the kidney where urine collects before entering the ureter. The bladder is an organ that stores urine until it is excreted from the body.
4. Where does fertilization, the fusion of sperm and egg, typically occur in the human body?
- A. Ovary
- B. Uterus
- C. Fallopian tube
- D. Vagina
Correct answer: C
Rationale: Fertilization typically occurs in the fallopian tube. This is where the sperm and egg meet and fuse to form a zygote. The fallopian tube provides the optimal environment for fertilization as it helps in the transportation of the egg and provides a suitable site for fertilization before the resulting embryo travels to the uterus for implantation. Choices A, B, and D are incorrect. The ovary is where eggs are produced, the uterus is where the fertilized egg implants and develops into a fetus, and the vagina is the canal that leads to the cervix, but fertilization itself does not occur in these locations.
5. What are the four types of cells in the gastric glands of the stomach mucosa?
- A. Endocrine, parietal, chief, mucous cells
- B. Parietal, mucous, goblet, endocrine cells
- C. Chief, parietal, goblet, lymphoid cells
- D. Goblet, lymphoid, parietal, chief cells
Correct answer: A
Rationale: The correct answer is A: Endocrine, parietal, chief, mucous cells. In the gastric glands of the stomach mucosa, the four types of cells are endocrine (producing hormones), parietal (secreting acid and intrinsic factor), chief (responsible for producing digestive enzymes), and mucous cells (providing protection to the stomach lining). These cells play essential roles in the digestive processes and maintaining the health of the stomach mucosa. Choices B, C, and D are incorrect because they do not accurately represent the types of cells found in the gastric glands of the stomach mucosa. Parietal cells secrete acid and intrinsic factor, chief cells produce digestive enzymes, and mucous cells provide protection, making these the correct choices in the context of gastric gland cellular composition.
