2. III. cranial nerve (n. occulomotorius)
Nuclei are located in tegmentum mesencephali (colliculi superiores):
nucleus n. oculomotorii (general somatic efferent fibres)
nucleus accessorius n. oculomotorii (general visceral efferent fibres)

go from oculomotor nerve
into the ciliary ganglion and
then form short ciliary nerves
for the innervation of ciliar muscle
and sphincter pupillae muscle.

4. Branches of the oculomotor nerve
Three branches!
r. superior
r. inferior
r. ad ganglion ciliare
(radix
parasympathica
ganglii ciliaris)
m. rectus superior
m. levator palpebrae
m. rectus medialis
m. rectus inferior
m. obliquus inferior
m. ciliaris
m. sphincter pupillae

5. IV. cranial nerve (n. trochlearis)
Nucleus is located in tegmentum mesencephali (colliculi inferiores):
nucleus n. trochlearis (general somatic efferent fibres)

6. IV. cranial nerve (n. trochlearis)
It has the longest way from the brain to the muscle that innervates!
Innervates the superior oblique muscle (m. obliquus superior).

Nucleus is located in tegmentum of rhomboid fossa (colliculus facialis):
nucleus n. abducentis (general somatic efferent fibres)

9. VI. cranial nerve (n. abducens)
