NEET PG DENTAL EXAM

Detailed explanation-1: -The abducens nerve, also known as cranial nerve VI, is responsible for ipsilateral eye abduction. Visualizing the anatomy of the nerve allows for better appreciation of the causes of abducens nerve palsy.

Detailed explanation-2: -The abducens nerve functions to innervate the ipsilateral lateral rectus muscle and partially innervate the contralateral medial rectus muscle (at the level of the nucleus-via the medial longitudinal fasciculus).

Detailed explanation-3: -Moebius syndrome is a rare neurological disorder characterized by weakness or paralysis (palsy) of multiple cranial nerves, most often the 6th (abducens) and 7th (facial) nerves. Other cranial nerves are sometimes affected. The disorder is present at birth (congenital).

Detailed explanation-4: -Sixth cranial nerve palsy affects the lateral rectus muscle, impairing eye abduction. The eye may be slightly adducted when the patient looks straight ahead. The palsy may be secondary to nerve infarction, Wernicke encephalopathy, trauma, infection, or increased intracranial pressure, or it may be idiopathic.
