What is the function of the trochlear nerve? Your trochlear nerve has one job: To supply movement (motor) information to your superior oblique muscle. Together, your trochlear nerve and superior oblique muscle make it possible for you to look down.
The trochlear nerve (/ ˈ t r ɒ k l ɪər /), [1] (lit. pulley-like nerve) also known as the fourth cranial nerve, cranial nerve IV, or CN IV, is a cranial nerve that innervates a single muscle - the superior oblique muscle of the eye (which operates through the pulley-like trochlea).
13 mar 2019 · The trochlear nerve is the fourth paired cranial nerve. It is the smallest cranial nerve (by number of axons) and the cranial nerve with the longest intracranial course. It has a purely somatic motor function.
15 lip 2023 · The trochlear nerve is the fourth cranial nerve (CN IV) and one of the ocular motor nerves that controls eye movement. The trochlear nerve, while the smallest of the cranial nerves, has the longest intracranial course as it is the only nerve to have a dorsal exit from the brainstem.
The trochlear nerve is the fourth Cranial Nerve (CNIV) with the longest intracranial course, but also the thinnest. It has a general somatic efferent (somatic motor) nerve, which innervates a single muscle (superior oblique muscle) on the contralateral side of its origin.
The trochlear nerve, also known as cranial nerve 4 (CN IV), controls the superior oblique muscle in your eye. This muscle allows you to move your eyeball down and shift your gaze...
