neurons are the building blocks of the nervous system. they process and transmit signals. in a neuron, the (1. cell membrane 2. myelin sheath 3. nucleus ) is found inside the (1. axon 2. cell body 3. dendrite )

In neurons, nuclei are found inside a cell body or cyton.

Neurons are the structural and functional units of the nervous systems. They are long in structure, and do have a cell body which is more or less spherical in shape and it has different projections. The projections are

A. Dendron - which are one to many in number and bring the impulse to the neuron from a synapse.

B. An axon which is always one in number and it transfers the impulse from the cell body to next neuron through a synapse.

The cyton or the cell body houses different types of cellular organelles like nucleus, ribosomes, lysosomes etc inside it. This nucleus houses the DNA and it produces necessary proteins required for maintaining required cellular functions.
