Abducens nucleus
Abducens Nucleus
The Abducens Nucleus (pronounced: ab-DOO-senz NOO-klee-us) is a collection of neurons that form a part of the brainstem. It is named after the Latin words "abducere" meaning "to lead away" and "nucleus" meaning "kernel".
Function
The primary function of the Abducens Nucleus is to innervate the lateral rectus muscle, which is responsible for the outward gaze of the eye. It does this by sending signals through the abducens nerve, also known as the sixth cranial nerve.
Location
The Abducens Nucleus is located in the dorsal part of the pons, a region of the brainstem. It is situated close to the midline, at the level of the junction between the pons and the medulla.
Clinical Significance
Damage to the Abducens Nucleus can result in abducens nerve palsy, a condition characterized by the inability to move the eye outward. This can be caused by a variety of factors, including stroke, tumor, and trauma.
