Nervous System

Nervous System

The two types of the nervous system are the

Central nervous system and the peripheral nervous system. They are

responsible for integrating, processing, and coordinating

Sensory data and motor commands the central nervous system, which interprets sensory input and carry information to maintain homeostasis. CNS can’t be regenerate because a CNS consists of the spinal cord that mean if it’s break the spinal cord is break also. The peripheral nervous system consists of the nerves that branch from the brain and spinal cord. It is a thick bundle of nerve fibers located within the spinal cord. The PNS can be regenerate and it will regrow.

The brain and spinal cord are the main parts of the nervous system. The brain controls every part of your body and is located top of our head inside our skull. The spinal cord with controls our movement. Nerve cells contain 3 parts: dendrites, cell body and the axon. Dendrite is the receiving part of the neuron. It is a short extension of the cell body

And send signals toward the cell body and the cell body conducts nerve impulses which in the transmission of the nerve impulses from the region to the other cell. The axon is a single extension carries the message to the next neuron, which controls all of the nerves.

The nerve impulse is response of the neuron. There are 3 classes of neurons: sensory neurons, motor neurons, and interneurons. Neurons are also called nerve cells.

A sensory neuron takes information from a receptor to the CNS.

A motor neuron takes information
