What are the parts of the nervous system and its function?

The function of the nervous system is to enable us to feel our surroundings. The five senses (sight, touch, hearing, taste and smell) have different sensory neurones in various parts of the body. The most sensitive parts of the body are the fingertips and lips, which have far more sensory neurones per square centimetre than other parts of the body. The nerve impulse travels from the sensory neurone, across a synapse (the gap between the end of one neurone and the dendrites (fingers) of the next) and reaches the next neurone. The signal reaches the coordinator (either the brain or spinal cord) and is then sent to a certain part of the body via a motor neurone, which eventually reaches the muscle and causes a movement. The nervous system is effected by stimulants and depressants, such as alcohol and drugs, which change the speed of reaction times.


What kind of action is a sneeze?

It is a reflex action which is an autonomic (automatic) nervous system reaction to stimuli. It is the respiratory system and the nervous system working together.
