Which of the following statement is NOT true?

Correct Answer: C

Rationale: Nerves are indeed bundles of axons (A, true). Neuralgia (B) is nerve pain, not a tissue (false, but not the answer). Axons begin at the axon hillock (D, true). Motor nerves (C) are not classified into 3 types (typically just somatic and autonomic), making it the false statement.

Correct Answer: C

Rationale: Gamma efferents adjust muscle spindle sensitivity and are influenced by higher centers (behavior, A; anxiety, B) and descending tracts (extrapyramidal, D). Scratching (C) is a motor action, not a direct controller of gamma efferents. C is the correct answer.

Correct Answer: C

Rationale: Midbrain reflexes include the hopping reaction (C) and placing reaction, adjusting limb position. Stretch reflex (A) is spinal, tonic neck reflex (B) is medullary/spinal, and positive supporting (D) is medullary. C is correct.

Correct Answer: D

Rationale: Dorsal columns carry vibration (D, correct), position, and fine touch, not crude touch (A, spinothalamic), temperature (B, spinothalamic), or pain (C, spinothalamic). D is correct.

Correct Answer: C

Rationale: Alpha waves are occipital (not temporal, A), beta waves are fast (not slow, B), theta waves are 4-7 Hz (C, correct), and EEG aids but isn’t 100% diagnostic (D). C is correct.
