Question

What does the Brain stem do?

Answer 1

Brainstem:

1. It is the posterior, stalk-like portion of the brain that extends into the spinal cord.
2. It is made up of the midbrain, pons, and medulla oblongata.
3. The brainstem sends messages to the rest of the body to regulate balance, breathing, and heart rate.
4. It regulates many essential involuntary functions such as breathing, heart rate, swallowing, sleeping, and eating.
5. The brain stem contains nuclei of all the cranial nerves except optic and olfactory nerves.
6. All information relayed from the body to the cerebrum and cerebellum and vice versa must traverse the brainstem.
