The nervous system is a communication center
The nervous system is responsible for us being able to understand and control what our senses perceive. It is essentially the communication center of our body. .
parts of the nervous system
The nervous system is made up of the brain, spinal cord, and nerves:
The brain: it is the organ that makes it possible for us to think, remember, feel and even dream. This organ connects to nerves present throughout the body. The nerves of our 5 senses send signals to the brain so that it understands what is happening in the outside world. The brain also sends messages through the nerves to the muscles to make our bodies move.
The spinal cord: is a set of nerves that connect the brain with the rest of the body. Most of the signals that the brain transmits are given through the spinal cord.
The nerves: the brain, like all parts of the nervous system, is made up of cells known as neurons. Neurons and other cells make up nerves. The nerves are responsible for sending the signals transmitted by the brain through our body. Likewise, the nerves send messages to the brain about the information we perceive through our senses.
nervous system functions
The nervous system is responsible for the functions of our body, thanks to it our heart beats, our lungs expand and contract to breathe and we blink. These are all involuntary movements. However, the nervous system also controls our voluntary movements such as running, jumping or walking.
Nervous system classification
The brain and spinal cord make up what is called the central nervous system. The set of nerves, neurons and ganglia are known as the peripheral nervous system.
Did you know . . . ?
✔ Thanks to the nervous system we can react instantly to danger. If an object is thrown close to your face, you will probably cover it with your hands or move to protect it.
✔ We can find around 100 billion neurons in our brain.
✔ The left side of the human brain controls the right side of the body and the right side of the brain controls the left side.
✔ While we sleep, nerves continue to send messages to the brain about the day’s events.
