Summary
The nervous system is composed of all nerve tissues in the body. The functions of nerve tissue are to receive stimuli, transmit stimuli to nervous centers, and to initiate response. The central nervous system consists of the brain and spinal cord and serves as the collection point of nerve impulses. The peripheral nervous system includes all nerves not in the brain or spinal cord and connects all parts of the body to the central nervous system. The somatic nervous system controls functions that are under conscious voluntary control such as skeletal muscles and sensory neurons of the skin. The autonomic nervous system, mostly motor nerves, controls functions of involuntary smooth muscles, cardiac muscles, and glands. In peripheral nervous system, a chemical neurotransmitter carries the nerve impulses from neuron to neuron across a synapse (space between neurons). The neurotransmitters are acetylcholine, norepinephrine, serotonin, and others.

Nervous System:
The nervous system is responsible for all the processes that make human life possible. It lets us think, dream, and have a lifetime of memories. It also handles our most basic, involuntary actions and reactions like blinking our eyes, keeping our body at the right temperature, breathing, and making our heart beat. It is the body’s way of communicating with itself and the outside world. Your nervous system is a network of electrical signals that are sent by neurons to tell your body what to do. These signals travel back and forth between your brain and other parts of your body via nerves in your spinal cord, which runs down through your spine.  The human nervous system can be divided into two separate systems the central nervous system (CNS) includes the brain and the spinal cord the peripheral nervous system (PNS) is composed of everything else.

The human nervous system is made up of the brain, the spinal cord, and the networks of nerves running throughout the body. It is composed of the central nervous system, the cranial nerves, and the peripheral nerves. The brain and spinal cord together form the central nervous system. The cranial nerves connect the brain to the head. The four groups of nerves that branch from the cervical, thoracic, lumbar, and sacral regions of the spinal cord are called the peripheral nerves. Main Functions Of Human Nervous System:

The nervous system has three main functions:
sensory input
integration of data
motor output
Sensory input is when the body gathers information or data, by way of neurons, glia and synapses. The nervous system is composed of excitable nerve cells (neurons) and synapses that form between the neurons and connect them to centers throughout the body or to other neurons. These neurons operate on excitation or inhibition, and although nerve...
