Which cranial nerve is responsible for muscles that move the eye and lids?
Oculomotor.
Vestibulocochlear.
Facial.
Trigeminal.
The Correct Answer is A
Choice A rationale
The oculomotor nerve (cranial nerve III) is responsible for innervating the muscles that move the eye and lift the eyelid, as well as controlling pupil constriction and lens shape for focusing.
Choice B rationale
The vestibulocochlear nerve (cranial nerve VIII) is involved in hearing and balance, not in the movement of eye muscles or eyelids.
Choice C rationale
The facial nerve (cranial nerve VII) controls muscles of facial expression, taste sensations from the anterior two-thirds of the tongue, and functions in tear and saliva production.
Choice D rationale
The trigeminal nerve (cranial nerve V) is responsible for sensation in the face and motor functions such as biting and chewing, not for eye movements.

Correct Answer is A
Explanation
Choice A rationale
The parietal lobe is responsible for processing sensory information and spatial awareness, including proprioception (the sense of body position in space). Damage to the parietal lobe can affect these functions.
Choice B rationale
The temporal lobe is involved in processing auditory information and memory, not spatial awareness. Damage to this lobe would affect hearing and memory rather than proprioception.
Choice C rationale
The frontal lobe is associated with executive functions, such as decision-making, problem-solving, and motor control, but not primarily with spatial awareness. Damage to this lobe impacts cognitive and motor functions.
Choice D rationale
The occipital lobe is primarily responsible for processing visual information. Damage to this lobe affects vision rather than spatial awareness or proprioception.
