The median plane, which divides the body into left and right. Your symptoms and the severity of the condition depend on whether both eyes are affected. This is also known as lateral rectus palsy and abducens nerve palsy. CN V: The Trigeminal Nerve. The sixth cranial nerve, also know as the Abducens nerve is a somatic efferent nerve which controls the movement of the lateral rectus muscle of the human eye. The lateral rectus muscle is one of the six extraocular muscles (the muscles that control the movement of the eye), responsible for the movement of the eye away from the midline (nose). This condition causes problems with eye movement. There are three divisions of the trigeminal nerve: Ophthalmic division (CN V1 or Va), Maxillary division (CN V2 or Vb), Mandibular division (CN V3 or Vc).
