what is the function of CN VI (abducens)?
lateral rectus (somatic motor)
The function of the abducens nerve (CN VI) is to control the movement of the lateral rectus muscle of the eye. The lateral rectus muscle is responsible for abducting or moving the eye laterally away from the midline of the face. When the abducens nerve is functioning normally, it sends signals to the lateral rectus muscle, allowing for the eyes to move laterally and maintain proper binocular vision. Dysfunction or damage to the abducens nerve can result in a condition called abducens nerve palsy, where the affected eye is unable to move laterally, leading to double vision and difficulty with eye coordination.
