Explain the nervous system

The Nervous system is a specialized system in animals. This system aids in the coordination of voluntary and involuntary actions, reflex actions in our body. 


Expert Solution


Nervous coordination involves the participation of our sense organs, nerves, spinal cord, and brain. The changes, which occurs around us can be easily detectable by our sense organs. This is because the nervous system has neurons at their tips, which consist of dendrites, cell body, nucleus, and axon. The information detected by dendrites are converted into impulses and are passed onto the cell body. Axon collects these impulses. At the nerve ending, electrical impulses are converted into chemicals and released. The chemicals will be passed to the next neuron through a gap called a synapse. This is how one neuron transfers the messages to another neuron.  


The neural system controls three types of actions: voluntary action, involuntary action, and reflex action.            

The nervous system consists of nerve cells (neurons). They transmit messages in the form of electrical impulses through neurons and convey to our sense organs.
