30 paź 2023 · The abducens (or abducent) nerve is the sixth paired cranial nerve (CN VI). Along with the oculomotor nerve (CN III) and the trochlear nerve (CN IV), it is a purely motor nerve responsible for controlling movement of the eyeball.
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.
21 lis 2022 · The nerve can be divided into 4 distinct portions: the nucleus, the cisternal portion, the cavernous sinus portion, and the orbital portion. The abducens nucleus resides in the dorsal pons, ventral to the floor of the fourth ventricle, and just lateral to the medial longitudinal fasciculus.
2 dni temu · The abducens nerve emerges from the brainstem, which sits low in the back of your brain and connects to the spinal column. It moves the eye outward (abduction) so you can look to the side. The specific area that this cranial nerve comes from is called the abducens nucleus.
Definition. IMAIOS. Number: VI. Name: Abducens. Sensory, motor, or both: Mainly motor. Origin/Target: Nuclei lying under the floor of the fourth ventricle, Pons. Nuclei: Abducens nucleus. Function: Innervates the lateral rectus, which abducts the eye. Located in the superior orbital fissure.
28 maj 2015 · Background: The sixth cranial nerve (CN VI) — or the abducens nerve — in humans supplies only the lateral rectus muscle. Due to its topographic conditions, including angulations and fixation points along its course from the brainstem to the lateral rectus muscle, the CN VI is vulnerable to injury.
10 kwi 2019 · It is a somatic motor cranial nerve with a nucleus deep within the pontomedullary junction that emerges anteriorly from the brainstem. In this article, we discuss the course of the abducens nerve and the role it plays in eye movements. Check out our summary of the cranial nerves here.
