Types of Neurons
Sensory Neurons
Sensory neurons respond to stimulus receptors such as touch, smell, sound, taste and sight. Sensory neurons send messages from areas such as nose to the brain or the spinal cord. They also send pain receptors to the brain or spinal cord.
Sensory neurons are also called afferent neurons. Sensory neurons such as vision, hearing, taste and smell do not use the spinal cord, while touch organs travel up the spinal cord to the brain. Sensory organs have very long axons. Sensory neurons deal with incoming messages.

Motor Neurons
Motor neurons carry messages from the brain and spinal cord to the glands and muscles. Motor neurons are also known as efferent neurons. Motor neurons deal with outgoing messages. Motor neurons have very long axons. Motor neurons carry nerve impulses from the brain and spinal cord to the muscles and glands.
Inter Neurons
Inter neurons are found within the brain and the spinal cord and eyes. Inter neurons intervene between sensory and motor neurons. Inter neurons carry messages from other inter neurons to the spinal cord and brain. Inter neurons carry impulses from sensory neurons to motor neurons. There are a lot more inter neurons than sensory and motor neurons. Inter neurons only have short axons.

How messages are relayed through the nervous system via neurons
Messages are sent and relayed through the nervous system with the use of neurons. Neurons are what carry the messages to the right part of the nervous system or the Neurons allow a response there are three different types of neurons.
Sensory Neurons:
These receive and carry impulses from the sense organs an send them to the brain or spinal cord.
Motor NeuronsThese neurons take impulses from the brain and spinal cord a send them to muscls or glands.
Inter NeuronsThese neurons connect the sensory neurons and the motor neurons to take action to the impulseWhen a sensory neuron receives a impulse, the impulses get carried to the cell body and carried through the axon to the end brush this is where the reaction carries out
SynapseA Synapse is the gap between the axon terminals and the dendrites.

Major parts of the Nervous System
Your nervous system is the control and communication system of the body. Its job is to send and receive messages. Your nervous system controls all your thoughts and movements.
The nervous system has 3 general or major functions, a sensory function, an interpretive function and a motor function.

Sensory nerves
Sensory nerves gather information from inside the body and from the outside environment. The nerves the carry the information to the central nervous system (CNS) sensory information that has been gathered and is brought to the CNS is processed and interpreted.
Motor nervesMotor nerves process information from the CNS to the muscles and glands of the body.

Central Nervous System (CNS)
The CNS consists of the brain and the spinal cord. These structures are protected by bone and cushioned from any injury that may occur.
The peripheral nervous system (PNS)
The peripheral nervous system (PNS) connects the central nervous system (CNS) to the rest of the body.
