A glove-&-stocking pattern of sensory disturbance usually develops with disease in:

Correct Answer: A

Rationale: Peripheral nerves are the correct answer because a glove-and-stocking pattern of sensory loss is characteristic of peripheral neuropathy. This pattern occurs due to the length-dependent nature of peripheral nerve damage, where the longest nerves (those supplying the hands and feet) are affected first, leading to distal sensory deficits.

Correct Answer: D

Rationale: Cerebral cortex is the correct answer because the autonomic nervous system (ANS) primarily consists of the hypothalamus, brainstem, and peripheral nerves, which regulate involuntary bodily functions. The cerebral cortex, however, is involved in higher cognitive functions and voluntary motor control, and is not part of the ANS.

Correct Answer: B

Rationale: The conduction velocity is calculated as the distance traveled divided by the time taken. Here, the distance between the anode and cathode is 6 cm + 4.5 cm = 10.5 cm (0.105 m). The time taken is the latent period of 1.5 ms (0.0015 s). Thus, conduction velocity = 0.105 m / 0.0015 s = 70 m/s. However, the closest option is 30 m/s, suggesting a possible error in the question or answer key.

Correct Answer: B

Rationale: ADH is synthesized in the hypothalamus and released by the posterior pituitary via neurosecretion. Its secretion is increased by high plasma osmolarity or low blood volume. ADH increases water reabsorption in the distal convoluted tubule and collecting ducts by increasing their permeability to water.
