Examples
- The nervus oculomotorius is the third cranial nerve that supplies extrinsic muscles of the eye, including the levator palpebrae superioris, superior rectus, medial rectus, inferior rectus, and inferior oblique muscles.
- Damage to the nervus oculomotorius can result in weakness or paralysis of the extrinsic muscles of the eye, leading to ptosis, diplopia, and limited eye movement.
- The nervus oculomotorius originates from the midbrain and courses through the cavernous sinus before entering the orbit to supply the extrinsic muscles of the eye.
- Injury to the nervus oculomotorius can occur due to trauma, aneurysm, or tumor compression, leading to dysfunction of the extrinsic muscles of the eye.
- The nervus oculomotorius also supplies the intrinsic muscles of the eye, including the sphincter pupillae and ciliary muscles, which control pupil constriction and lens accommodation.
