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.
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).
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.
30 paź 2023 · The trochlear nerve is a purely motor nerve, responsible for providing general somatic efferent (GSE)/motor innervation to just one muscle, the superior oblique muscle of the eye, on the contralateral side of its associated nucleus.
Your trochlear nerve, also known as the cranial nerve 4 or CN IV, is a motor (movement) nerve that sends signals from your brain to one of the muscles that control eye movement. You have two trochlear nerves — one for each eye .
12 lip 2023 · The trochlear nerve (CN IV) is a paired cranial nerve that is responsible for innervating the superior oblique muscle. As a result, it causes the eyeball to move downward and inward.
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.
