What is the name of Cranial Nerve III?

Cranial Nerve III is known as the Oculomotor nerve. This nerve plays a critical role in eye movement and also contributes to the regulation of the pupil and lens shape. It innervates most of the extraocular muscles, which are responsible for movements such as looking up, down, and medially. Additionally, it controls the muscles that constrict the pupil and those responsible for accommodation (focusing on near objects). Understanding the function of the Oculomotor nerve is essential for recognizing how various cranial nerves interact to facilitate visual tracking and eye movement, making it fundamental in both clinical settings and anatomy studies.
