[[ファイル:Cranial03.jpg|left|400px]]眼球運動させる筋肉のうち、上斜筋は滑車神経（第Ⅳ脳神経）、外転筋は外転神経（第Ⅵ脳神経）の働きです。他の動眼筋はすべて動眼神経（第Ⅲ脳神経）の働きです。毛様体(遠近調節)の運動、まぶたを持ち上げる上眼瞼拳筋の運動も動眼神経（第Ⅲ脳神経）の働きです。まぶたを閉じる眼輪筋は、顔面神経（第VII脳神経）の働きです。

The trochlear nerve (number IV cranial nerve) functions as the nerve for superior oblique muscle and the abducens nerve (number VI cranial nerve) functions as the nerve for eyeball abduction.  The oculomotor nerve (number III cranial nerve) functions as nerve for all other muscles that move the eyeball. 
The oculomotor nerve (number III cranial nerve) also functions as the nerve for ciliary muscles (focusing) and levator palpebrae superioris, which opens the eyelid.  The facial nerve (number VII cranial nerve) functions as the nerve for muscles of facial expression including orbicularis oculi muscle, which closes the eyelid. 
The oculomotor nerve (number III cranial nerve) functions as the nerve for pupillary sphincter, which decreases the size of the pupil. Meanwhile, the nerve for the pupillary dilator, which increases the size of the pupil is from the cervical sympathetic ganglia.
