1. Which part of the brain is responsible for processing vision?

• A. Occipital lobe
• B. Frontal lobe
• C. Temporal lobe
• D. Parietal lobe

Correct answer: A

Rationale: The occipital lobe is the part of the brain responsible for processing visual information. Located at the back of the brain, the occipital lobe contains the primary visual cortex, which plays a crucial role in interpreting visual stimuli received from the eyes. The frontal lobe is primarily involved in higher cognitive functions, decision-making, and motor control, not vision processing. The temporal lobe is responsible for auditory processing, memory, and emotion, not vision. The parietal lobe is involved in sensory integration, spatial awareness, and perception of stimuli, but not specifically for visual processing.

2. What is the longest bone in the human body?

• A. Tibia
• B. Fibula
• C. Femur
• D. Humerus

Correct answer: C

Rationale: The femur is indeed the longest bone in the human body. It extends from the hip to the knee, providing crucial support for the body's weight and enabling various movements. The tibia and fibula are bones in the lower leg, while the humerus is located in the upper arm. Therefore, choices A, B, and D are incorrect in this context.

3. Which of the following is NOT a major division of the nervous system?

• A. Peripheral nervous system
• B. Central nervous system
• C. Somatic nervous system
• D. Autonomic nervous system

Correct answer: C

Rationale: The correct answer is C: Somatic nervous system. The major divisions of the nervous system are the central nervous system, which includes the brain and spinal cord, and the peripheral nervous system, which includes all the nerves outside of the central nervous system. The somatic nervous system, which controls voluntary movements and reflexes, is a part of the peripheral nervous system. The autonomic nervous system is another subdivision of the peripheral nervous system that regulates involuntary functions like heart rate and digestion. Therefore, the somatic nervous system is not a major division of the nervous system, making it the correct answer.

4. Where does fertilization typically occur in the female reproductive system?

• A. uterus
• B. fallopian tube
• C. endometrium
• D. ovary

Correct answer: B

Rationale: Fertilization typically occurs in the fallopian tube, specifically in the ampulla, which is the widest part of the tube. After ovulation, the released egg travels through the fallopian tube where it may encounter sperm for fertilization to take place. The fallopian tube provides the ideal environment for fertilization due to the presence of cilia that help move the egg and sperm towards each other. The uterus is where the fertilized egg will implant and develop into a fetus, not where fertilization occurs. The endometrium is the lining of the uterus that thickens to support a potential pregnancy but is not the site of fertilization. The ovary releases the egg during ovulation but is not where fertilization occurs.

5. Which muscle is voluntary, striated, and found attached to bones?

• A. Smooth muscle
• B. Skeletal muscle
• C. Cardiac muscle
• D. Epithelial muscle

Correct answer: B

Rationale: The correct answer is B, Skeletal muscle. Skeletal muscle is both voluntary and striated, as well as attached to bones, allowing for movement. Smooth muscle, on the other hand, is involuntary and typically found in the walls of internal organs, controlling functions like digestion. Cardiac muscle is also striated, but it is involuntary and specifically found in the heart, responsible for cardiac contractions to pump blood. 'Epithelial muscle' is an incorrect term; epithelial tissue is a type of tissue that forms the linings of various body surfaces and structures, not a muscle type.
