Nervous system

Parts

CELL BODY: Controls the metabolism of the nerve cell

AXON: A long fibre which carries information away from the cell body

DENDRITES: Collect information from other cells

FATTY SHEATH(MADE OF MYELIN): Gives electrical insulation between neighbouring cells and makes impulses travel faster

END PLATE: Synapses with another nerve cell, muscle or gland

Different types of nervous system

Central Nervous System

Peripheral Nervous System

Uses the brain and spinal cord

Processing centre

All the nerves that branch off from the brain and spinal cord

Voluntary

Involuntary

Reflex actions: Rapid automatic responses to a stimulus which many times pose danger to our body

Neurons

Relay neuron

Sensory neuron

Motor neuron

In charge of an action according to the stimulus

Senses the stimulus

Makes the response quicker by not taking the information to the brain

Brief explanation

Controls the ability to move, breathe, see, think and more

Sensation, integration and response

Helps all the parts of the body to communicate with each other

The dendrites collect the informations from other cells and the end plate synapses with another nerve cell. This process repeats and repeats making the whole nervous system work. They work according to the human body's need, such as preventing a human of getting hurt.
