1. Which of the following statements is anatomically correct?

• A. The knee is distal to the ankle.
• B. The heart is inferior to the diaphragm.
• C. The hip is proximal to the knee.
• D. The wrist is proximal to the elbow.

Correct answer: C

Rationale: The term 'proximal' refers to a body part being closer to the center of the body or a point of reference. In this case, the hip is closer to the center of the body compared to the knee, which makes the statement anatomically correct. Choice A is incorrect as the knee is proximal to the ankle. Choice B is incorrect as the heart is superior to the diaphragm. Choice D is incorrect as the elbow is proximal to the wrist.

2. Which part of the brain is responsible for processing emotions?

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

Correct answer: B

Rationale: The correct answer is the amygdala. It is a small, almond-shaped structure located within the temporal lobe of the brain. The amygdala plays a crucial role in processing emotions such as fear, anger, pleasure, and other emotional responses. It is involved in the formation of emotional memories and helps regulate emotional responses to various stimuli. The frontal lobe is mainly responsible for higher cognitive functions such as decision-making and problem-solving, not processing emotions. The parietal lobe is involved in processing sensory information and spatial awareness, while the occipital lobe is primarily responsible for processing visual information.

3. Which part of the brain monitors and controls the body's movement?

• A. Top, middle portion of the parietal lobe
• B. Back of the head
• C. Front portion of the parietal lobe
• D. Around the auditory cortex

Correct answer: C

Rationale: The correct answer is the front portion of the parietal lobe. The motor cortex, located in this area, is responsible for planning, controlling, and executing voluntary movements. It plays a crucial role in coordinating the body's movement. Choice A, the top, middle portion of the parietal lobe, is incorrect as this region is more involved in processing sensory information rather than controlling movement. Choice B, the back of the head, is incorrect as it typically refers to the occipital lobe responsible for processing visual information. Choice D, around the auditory cortex, is incorrect as the auditory cortex is primarily involved in processing auditory information, not controlling body movement.

4. What is the primary function of the circulatory system?

• A. To produce hormones
• B. To transport oxygen and nutrients
• C. To fight infections
• D. To regulate body temperature

Correct answer: B

Rationale: The circulatory system's primary function is to transport oxygen, nutrients, and hormones to cells and remove waste products. Choice A is incorrect because hormone production is primarily carried out by endocrine glands. Choice C is incorrect as fighting infections is a role of the immune system. Choice D is incorrect as regulating body temperature is mainly controlled by the integumentary and nervous systems.

5. Which muscle group is primarily responsible for extending the knee?

• A. Hamstrings
• B. Quadriceps
• C. Calves
• D. Glutes

Correct answer: B

Rationale: The quadriceps, a group of muscles located on the front of the thigh, are primarily responsible for extending the knee joint. When the quadriceps contract, they work to straighten the knee, allowing for actions like kicking or standing up from a seated position. The hamstrings (Choice A) are responsible for flexing the knee, the calves (Choice C) primarily work on plantar flexion at the ankle joint, and the glutes (Choice D) are mainly involved in hip extension.
