Parts of Neuron
1. Cell body
2. Axon (single axon)
3. Dendrites
Cell body
Cell bodies varies size and shapes. They are too small to be seen by nacked eye.
Cell body contains nucleus and other cell organelles.
Cell body has large nucleus which contains nucleolus that are responsible for the metabolism, growth and repair of Neuron.
Cell body consist -
nissle bodies (RER and free ribosome)
endoplasmic reticulum
lysosome
mitochondria
neurofilaments
golgi bodies
Cell body connects to dendrites which bring information into the neuron and axon which send the information to other neurons.
Cell body form grey matter of the nervous system and are found at the PNS of brain and in the center of spinal cord.
Cluster of cell bodies in central nervous system called nuclei.
Cluster (group) of cell bodies in peripheral nervous system called ganglion.
Bundle of neuron are called tracks in CNS and nerves in PNS.
