The levator palpebrae superioris muscle, which helps in raising the upper eyelid, is supplied by the Oculomotor nerve. This is also known as the third cranial nerve or CN III. Here are the steps to understand this:

1. Identify the muscle in question: The levator palpebrae superioris is a muscle in the orbit that elevates and retracts the upper eyelid.

2. Understand the function of cranial nerves: Cranial nerves are the nerves that emerge directly from the brain, including the brainstem, in contrast to spinal nerves, which emerge from segments of the spinal cord.

3. Identify the specific cranial nerve: The Oculomotor nerve (Cranial Nerve III) is responsible for controlling most of the eye movements and pupil constriction. It also supplies the levator palpebrae superioris muscle, allowing it to perform its function of lifting the upper eyelid.
