The somatic nervous system (SNS) is the part of the peripheral nervous system that controls voluntary movement and processes external stimuli through two types of neurons: motor neurons (activating muscles) and sensory neurons (relaying information to the central nervous system).| 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
Schwann cells are a special type of cell found in the peripheral nervous system (PNS). They play a key role in helping nerves work efficiently by wrapping around nerve fibers and forming a protective layer called the myelin sheath.| Simply Psychology
The Central Nervous System (CNS) consists of the brain and spinal cord. It acts as the body's control center, processing sensory information and directing responses. The CNS coordinates both voluntary activities, like movement, and involuntary ones, such as breathing and heartbeat.| Simply Psychology
A neuron is a nerve cell that processes and transmits information through electrical and chemical signals in the nervous system. Neurons consist of a cell body, dendrites (which receive signals), and an axon (which sends signals). Synaptic connections allow communication between neurons, facilitating the relay of information throughout the body.| Simply Psychology
