The hindbrain usually consists of three different parts; cerebellum, medulla and the pons.

The medulla ultimately controls unconscious activities such as breathing, blood flow and your heartbeat. It is situated next to the spinal cord.
The pons affect everyday activities such as dreaming, waking up and sleeping.
