Oculomotor Nerve (Noun)
Meaning
Supplies extrinsic muscles of the eye.
Classification
Nouns denoting body parts.
Examples
- The oculomotor nerve is responsible for supplying the majority of the extrinsic muscles of the eye, controlling its movement and orientation.
- Damage to the oculomotor nerve can result in impaired eye movement, with the affected eye having limited ability to move upward and outward.
- The oculomotor nerve originates in the brainstem and travels through the cavernous sinus before reaching the orbit, where it supplies the extrinsic muscles of the eye.
- As the oculomotor nerve enters the orbit, it divides into two branches that innervate the muscles responsible for moving the eye.
- Lesions of the oculomotor nerve can result in ptosis, strabismus, and limited eye movement, as the affected eye is unable to properly respond to neural signals sent by the brain.
