CN in the medulla
9-12
Upper dorsal boundary of medulla
Stria medullaris
Upper dorsal boundary of pons
Exit of CN 4
Tissue dorsal to plane of cerebral aqueduct
Tectum
Most ventral segment of brainstem containing descending motor cortical tracts
Basis
Core between tectum and basis containing CN nucleu, ascending sensory tracts
Tegmentum
Massive bundle fibers connecting cerebral cortex with the brainstem
Crus cerebri or cerebral peduncles
Fossa where CN 3 oculomotor exits
Interpenduncular fossa
CN exiting on the dorsal surface of the midbrain
CN 4 trochlear
Visual relay nucleus connecting to lateral geniculate body in diencephalon
Superior colliculus
Auditory relay nucleus connecting medial geniculate body in the diencephalon
