Brain Stem components

What are the three brain stem components and what fetal division do they come from?

Midbrain- mesencephalon

Pons- metencephalon

Medulla Oblongata- myelencephalon

superior colliculus

subconsciously process visual information to make an involuntary response

inferior colliculus

subconsciously process auditory information to make an involuntary response

substantia nigra

regulates motor output of cerebral nuclei by making dopamine (NT)

Red nucleus

fine motor control

cerebral peduncles

connect cerebrum to remainder of brain stem, carry info between cerebrum, brain stem, and cerebellum

pons

contains descending and ascending tracts, contains autonomic nuclei in pontine, respiratory center to help regulate breathing

cerebellum

fine tunes motor commands from cerebrum, makes adjustments to muscle activity, using proprioception, to maintain equilibrium and posture. Muscle memory and motor learning

medulla oblongata

pyramids have motor projection tracts where information crosses over, olives relay proprioceptive information to the cerebrum, contains many autonomic nuclei: cardiac center, vasomotor center, respiratory center

pontine nuclei

relay information from the cerebral cortex to the cerebellum for voluntary motor control.
