Document Summary
Pupilary light reflex: constriction of pupil to light. Accommodation reflex: reflex changes that enable an object to be focused on the retina. Inferior oblique: controls upward and medial eye gaze. Downward movement of the eye when in medial position. Innervates tensor tympani and other small muscles. Carries information concerning tactile, propioceptive, pain, and temperature in the head. Inability to move eye medially or laterally. Abnormal pupillary light reflex: absense of pupillary constriction. Diplopia when attempting to move eyes downward (difficulty in descending stairs and reading) Douloureux): characterized by brief attacks of excruciating pain in the distribution of. Only cranial nerve that is a) attached to dorsal surface of brainstem and b) completely crossed. Tract: part of main sensory nucleus, gives rise to important one or more divisions of nerve. Participate in reflex activities (swallowing and coughing) Innervate muscles of facial expression and stapedius. Facial motor nucleus involved in corneal blink reflex.
