Draw the structure of a neuron and explain its function.
Neurons are the functional units of the nervous system. The three main parts of a neuron are axon, dendrite, and cell body.
Structure of a neuron
Functions of the three parts of a neuron:
Axon: It conducts messages away from the cell body.
Dendrite: It receives information from axon of another cell and conducts the messages towards the cell body.
Cell body: It contains nucleus, mitochondria, and other organelles. It is mainly concerned with the maintenance and growth.
