1. Which part of the nervous system includes the femoral, radial, and ulnar nerves?

• A. Somatic
• B. Autonomic
• C. Sympathetic
• D. Parasympathetic

Correct answer: A

Rationale: The correct answer is A: Somatic. The femoral, radial, and ulnar nerves are all part of the somatic nervous system, responsible for controlling voluntary movements and sensory input. These nerves innervate muscles and skin throughout the body, allowing conscious control of movements and sensations. The somatic nervous system is distinct from the autonomic nervous system, which regulates involuntary bodily functions. Choices B, C, and D are incorrect because the autonomic nervous system (B) is responsible for involuntary functions, while the sympathetic (C) and parasympathetic (D) divisions are subdivisions of the autonomic nervous system, not the somatic nervous system.

2. When an individual is under stress, hormones are released. Which of the following is not one of the locations where hormones are released when under stress?

• A. Parathyroid gland
• B. Adrenal cortex
• C. Posterior pituitary
• D. Hypothalamus

Correct answer: A

Rationale: The parathyroid gland is not a location where hormones are typically released during stress. It primarily regulates calcium levels in the blood through the release of parathyroid hormone (PTH). On the other hand, the adrenal cortex releases hormones like cortisol in response to stress, the posterior pituitary releases oxytocin and antidiuretic hormone, and the hypothalamus plays a crucial role in coordinating stress responses through the release of corticotropin-releasing hormone (CRH). Therefore, the parathyroid gland is the correct answer as it is not directly involved in the stress response pathway.

3. Which hormone stimulates milk production in the breasts during lactation?

• A. norepinephrine
• B. antidiuretic hormone
• C. prolactin
• D. oxytocin

Correct answer: C

Rationale: During lactation, the hormone responsible for stimulating milk production in the breasts is 'prolactin.' Prolactin plays a crucial role in initiating and maintaining lactation by promoting the development of alveoli in the mammary glands and stimulating milk synthesis. While oxytocin is involved in the ejection of milk from the breasts, it is prolactin that primarily governs milk production. Norepinephrine is not directly involved in milk production, and antidiuretic hormone primarily regulates water balance and blood pressure, not milk production.

4. How might an injury to the parietal lobe impact an individual?

• A. Breathing
• B. Attention
• C. Memory
• D. Perception

Correct answer: D

Rationale: An injury to the parietal lobe can impact an individual's perception, affecting their ability to interpret sensory information such as touch, spatial orientation, and recognizing objects. The parietal lobe is crucial for integrating sensory information and creating a coherent perception of the surrounding world. Damage to this area can lead to challenges with spatial awareness, object recognition, and accurate processing of sensory input. Choices A, B, and C are incorrect because breathing, attention, and memory are primarily associated with other brain regions such as the brainstem, frontal lobe, and temporal lobe respectively, not the parietal lobe.

5. Which part of the respiratory system is in the upper respiratory tract?

• A. Bronchioles
• B. Alveolar ducts
• C. Alveoli
• D. None of the above

Correct answer: D

Rationale: The upper respiratory tract includes structures such as the nose, nasal cavity, pharynx, and larynx. These structures are responsible for filtering, warming, and humidifying the air. The lower respiratory tract comprises the trachea, bronchi, bronchioles, alveolar ducts, and alveoli. Bronchioles, alveolar ducts, and alveoli are all part of the lower respiratory system, involved in gas exchange. Therefore, the correct answer is 'None of the above' as none of the listed options are part of the upper respiratory tract.
