=Forebrain= =Midbrain and basal ganglia=

General vasculature and organization
The cerebral aqueduct divides the midbrain into dorsal and ventral portions.

Tectum

 * Superior colliculus
 * Inferior colliculus

Basal ganglia
=Hindbrain= =Cranial nerves=

Oculomotor nerve (III)

 * Brainstem nucleus:
 * Edinger–Westphal nucleus (parasympathetic pre-ganglionic neuron cell bodies that synapse onto the ciliary ganglion)
 * Contributes the autonomic, parasympathetic component to the oculomotor nerve; ultimately innervating iris sphincter muscle and ciliary muscle
 * Oculomotor nucleus - general somatic efferent fibers to the levator palpebrae superioris muscle, superior rectus muscle, inferior rectus muscle, medial rectus muscle and inferior oblique muscle

=Neural tracts (ascending and descending) =

=Spinal cord= =Cervical plexus=
