30 paź 2023 · The abducens nerve (CN VI) arises from its associated nucleus (nucleus of abducens nerve) located beneath the floor of the fourth ventricle in the caudal pons. Nerve fibers pass anteriorly through the pons to emerge from the medullopontine sulcus at the junction between the pons and the pyramid of the medulla ( pontomedullary junction ).
13 mar 2019 · The abducens nerve is the sixth paired cranial nerve. It has a purely somatic motor function – providing innervation to the lateral rectus muscle. In this article, we shall look at the anatomy of the abducens nerve – its anatomical course, motor functions and clinical relevance.
1 paź 2024 · Location. The abducent nerve originates in the pons of the brainstem, specifically in the abducens nucleus, located near the floor of the fourth ventricle. It exits the brainstem at the junction of the pons and medulla and travels forward through the subarachnoid space.
21 lis 2022 · Structure and Function. Unlike the oculomotor and trochlear nerve, the abducens nerve is a purely motor nerve, meaning the nerve has no sensory function (see Image. The Abducens Nerve). Its main function is to carry general somatic efferent nerve axons to innervate the lateral rectus muscle, which then abducts the eye on the ipsilateral side.
The abducens nerve (CN VI) is a motor nerve that carries general somatic efferent fibers to exclusively innervate the lateral rectus muscle of the eye. Twelve cranial nerves, their exit points, anatomical course, branches and topography.
