Hindbrain
The hindbrain or reptilian brain is the oldest part of the human brain. This is a piece of our brain anatomy that we share with reptiles and is most important. This part of the brain is in charge of instincts and the most basic functions. For example survival, dominance, mating, respiration, and heartbeat all come from this section. Within the hindbrain there are four different parts; one would be the Spinal Cord, the Medulla Oblongata, the Pons, and the Cerebellum.

The spinal cord is the information superhighway of the body. It carries information up the brain and back down. The medulla oblongata controls the automatic functions like respiration, digestion, and heart rate. It also is a relay station for signals going to and from the brain. The pons has to do with the level of arousal and sleeping. It is involved with controlling automatic body functions. The cerebellum deals with movement. It regulates movement, posture, and balance. It is also involved in learning movements.
