Neuron: Function And Parts
Neurons are specialized. Their specific function is to allow our brains to learn, reason, and remember. The brain includes billions of neurons, so does your spinal cord and all the nerves that branch out from the spinal cord to the bodys glands, organs, and muscles. Each neuron is a cell that uses biochemical reactions to receive, process and transmit information.
Each neuron may have thousands of branches that connect it to other neurons. The branches are called dendrites or axons. Dendrites are short fibers that extend from the neuron cell body which receive information from other neurons and sensory receptors. Axons, long fluid-filled tubes, carry messages away from the cell body to another neuron.
Once the information is passed through the dendrites it is received by the cell body (soma). The soma and the enclosed nucleus don't play a significant role in the processing of incoming and outgoing data. Their primary function is to perform the continuous maintenance and energy
