The brainstem is the stalk-like lower part of the brain that connects the main brain (cerebrum) to the spinal cord. It sits at the base of the skull, just above the spinal cord, and is considered part of the central nervous system (CNS).| Simply Psychology
The human brain is a complex organ, made up of several distinct parts, each responsible for different functions. The cerebrum, the largest part, is responsible for sensory interpretation, thought processing, and voluntary muscle activity. Beneath it is the cerebellum, which controls balance and coordination. The brainstem connects the brain to the spinal cord and oversees automatic processes like breathing and heart rate. The limbic system, containing structures like the hippocampus and amygd...| Simply Psychology
The peripheral nervous system (PNS) is critical for connecting the central nervous system (CNS) to the rest of the body. It is essential for bodily functions such as movement, sensation, and autonomic processes.| Simply Psychology

It is also called the ‘rest and digest' system as it conserves the body’s natural activity and relaxes the individual once an emergency has passed.
