Question 9

A Brain Stem that is responsible for the auditory reflexes. Where can you find this brain stem?

Answer 9

Mesencephalon (Mid Brain). It is located below the cerebrum.

Question 10

It is a brain stem that is responsible for certain reflexes actions (chewing, tasting and saliva production). Where can you find this brain stem?

Answer 10

Pons. It is Located below the mid brain.

Question 11

This brain Stem connects to the spinal cord. It regulates heart & blood vessel function, digestion, respiration, swallowing, coughing, sneezing and blood pressure. Where can we find this brain stem? It is known as the
“_ _ _ _ _ _ of _ _ _ _ _ _ _ _ _ _”.

Answer 11

Myelencephalon (Medulla Oblongata). It is Located at the bottom of the brainstem.
“Center of Respiration”.
