Neurons are the cells that is involved in sending and receiving signals.
Further Explanation:
The nervous system consists of neurons which are involved in transmitting the information to other nerve cells, gland cells and muscle.
<u>Neurons consists of the following:</u>
1. Cell body: It contains the nucleus and cytoplasm.
2. Axons: It extends from cell body and contains smaller branches.
3. Dendrites: It extends from the cell body and takes message or the signal from other neurons.
4. Synapsis: Point of communication between two neurons.
5. Synaptic cleft: It is the space between two cells.
6. Efferent neuron: The neurons which sends the information away from the central nervous system to glands.
7. Myelin sheath: It is the fatty materials that surrounds some axons.
8. Neurotransmitter: It is the type of chemical that is released from the tip of axons to the synaptic cleft whenever the nerve impulses arrives.
9. Afferent neuron: This type of neurons sends the information from the sensory receptors to the central nervous system.
10. Nodes of Ranvier: It is the space between the myelin sheath.
11. Action potential: It is the reversal of electrical potential present in the plasma membrane of the neuron.
12. Interneuron: This is the type of neuron that sends the information between the sensory neurons and the motor neurons.
