Brainstem
The brain stem includes the medulla/ medulla oblongata,
pons/ pons and
midbrain /mesencephalon. The brainstem receives sensory information
and conveys motor function from cranial nerves. It also serves
as a conduit for information from ascending sensory and descending
motor tracts. Portions of the medulla participate in essential
blood pressure and respiratory functions The pons participate in
the regulation of eye movements. Pons gets blood supply from the
basilar artery/ a.basilaris. The anterior spinal artery/ a.spinalis
anterior derived from the vertebral artery/ a.vertebralis provides
blood supply of medulla.
