Question

all mm of eye are supplied by CNIII except 2. what are the exceptions and what is the innervation? match: A: lateral rectus B: superior oblique C: CNIV D: CNVI

Answer 1

The correct matching is:

A: Lateral Rectus - D: CN VI (Abducens nerve)

B: Superior Oblique - C: CN IV (Trochlear nerve)

Step-by-step explanation:

In the eye, most extraocular muscles are innervated by the oculomotor nerve (CN III). However, there are two exceptions:

• Lateral Rectus (A): Innervated by the Abducens nerve (CN VI).
• Superior Oblique (B): Innervated by the Trochlear nerve (CN IV).

The medial rectus, superior rectus, inferior rectus, and inferior oblique are innervated by CN III (Oculomotor nerve).

The lateral rectus is innervated by CN VI (Abducens nerve).

The superior oblique is innervated by CN IV (Trochlear nerve).
