Neurons are the core elements of the nervous system. They receive, integrate, and transmit information through electrical impulses and communicate with other neurons via chemical signals. The three main components of a neuron are the cell body, which contains the nucleus, dendrites that receive messages and transmit them to the cell body, and the axon, which transmits messages to other neurons. Additional components include a myelin sheath made of Schwann cells that surrounds axons and dendrites, and the neurilemma, a cytoplasmic layer that allows regeneration of damaged nerves.

2. Neuron
 Core element of the nervous system
 Receive, integrate, and transmit
information
 Operate through electrical impulses
 Communicate with other neurons
through chemical signals

4. Components of Neuron
there are basically three core
component of neuron
Cell Body
Dendrites
Axon

5. Cell Body
Thecell body contains a
nucleus or control centre.

6. Dendrite
branching extensions of
a neuron that receive
messages and conduct
impulses toward the cell
body

7. Axon
the extension of a
neuron, ending in
branching terminal
fibers, through which
messages are sent to
other neurons

8. Beside these,
there are two more parts in
neuron
Myelin Sheath (Schwann
Cells)
Neurilemma

9. Myelin Sheath (Schwann
Cells).
 Myelin sheath is a white
segmented covering made
up of Schwann cells.
 The covering is around
axons and dendrites of
many peripheral neurons.

10. Neurilemma
 Neurilemma is the
nucleated cytoplasmic layer
of the Schwann cell.
 Neurilemma allows
damaged nerves to
regenerate.
