List the 3 regions of the Brain Stem?

Midbrain/Mesencephalon, Pons, & Medulla Oblongata

What structures are in the Midbrain & what is it's function?

Superior & Inferior Colliculi, Reticular Activating System (RAS) Main motor pathway between the cerebrum & the lower parts of the nervous system

What structures are in the Pons & what is their function?

Apneustic & Pneumotaxic centers; helps controls facial muscles, bring sensory information from the inner ear, helps control respiratory rate, carries both sensory & motor info to the cerebellum, thalamus, & down the spinal cord

What structures are in the Medulla Oblongata?

Vital reflex center; Cardiac, Vasomotor, & Respiratory

Functions of the Medulla Oblongata?

Helps control heartbeat, blood pressure, and respiration

Where is the Sensory & Motor nuclei located and what is it's function?

Medulla Oblongata; Provide motor control to muscles in neck, back, & some organs, provides sensory info from inner ear, links ascending & descending tracts between the spinal cord & brain.

Function of the Reticular Formation?

Alerts the cerebrum to a state of conscious

What area of the brain contains the apneustic & the pneumotaxic center?


Function of Apneustic & Pneumotaxic centers?

Adjust /control respiratory rate

Which area of the brain stem contains the vital reflex centers?

Medulla Oblongata

What types of variables are controlled by the Vital reflex center?

heart beat, blood pressure, respiration
