In central cord syndrome there is:

Correct Answer: C

Rationale: Central cord syndrome (often cervical) damages the central spinal cord, affecting motor (upper limbs > lower) and pain/temperature sensation, while touch sensation (dorsal columns) often remains intact due to its peripheral location.

Correct Answer: B

Rationale: The facial nerve (CN VII) doesn’t supply the ciliary ganglion (CN III does via parasympathetic fibers). It supplies facial muscles, buccinator, taste (anterior 2/3 tongue), and the greater petrosal nerve.

Correct Answer: B

Rationale: The sensory root of CN VII is the nervus intermedius, carrying taste and parasympathetic fibers, exiting via the internal acoustic meatus, not foramen ovale.

Correct Answer: D

Rationale: The midbrain contains oculomotor (CN III) nuclei, lying between the pons and diencephalon in the posterior cranial fossa.

Correct Answer: B

Rationale: The anterior cerebral artery supplies the medial cortex (contralateral leg, micturition/defecation areas). Middle cerebral supplies lateral cortex (arm, face, speech).
