Section of the Nervous System in Humans
In general, the nervous system consists of several parts, namely the brain, spinal cord, and nerve cells (neurons). The functions of these parts are related to one another. Here is the explanation:
- Brain
The brain is the control center whose job is to regulate all functions in the body, starting from movement, secretion or secreting hormones, thinking or cognitive power, sensations, to emotions.
- Spinal cord
The spinal cord is part of the central nervous system. Some stimuli that are reflexes can pass through the spinal cord without going through the brain.
- Nerve cells (neurons)
Neuron is the working unit of the central nervous system. Consists of 12 cranial nerves, all spinal nerves, and their branches. Its function is as a conductor of information in the form of stimuli or impulses. With the presence of these nerve cells, both organs and movement systems can respond as they should.
