The medulla, pons, and cerebellum are all part of the:

A) midbrain.
B) hindbrain.
C) spinal cord.
D) forebrain.

The medulla, pons, and cerebellum are all located in the hindbrain, which is the region of the brain that is responsible for regulating vital functions such as heartbeat and breathing, as well as coordinating movement and balance. The midbrain is located above the hindbrain and is involved in sensory processing and motor control, while the forebrain is responsible for more complex functions such as thought, learning, and memory. The spinal cord is a long, thin, cylindrical bundle of nerves that extends from the brainstem to the lower back and is responsible for transmitting sensory information and motor signals between the brain and the rest of the body.
