Question

What does a neuron look like?

Answer 1

Neuron:

1. A neuron is a specialized cell, primarily involved in transmitting information through electrical and chemical signals.
2. Neurons are the structural and functional units of the nervous system.
3. The structure of a neuron varies with their shape and size and it mainly depends upon their functions and their location.

Structure of a neuron:

1. The neuron is the longest cell of the human body.
2. It is a specialized and individual cell, which is also known as the nerve cell. A group of neurons forms a nerve.
3. It has tiny hair-like filaments that emerge from its terminals, giving it the appearance of a small tree.
4. Dendrites: A branch-like structure of the neuron that functions by receiving messages from other neurons and allow the transmission of messages to the cell body.
5. Cell Body: Each neuron has a cell body with a nucleus, Golgi apparatus, endoplasmic reticulum, mitochondria and other components.
6. Axon: Axon is a tube-like structure that functions by carrying an electrical impulse from the cell body to the axon terminals for passing the impulse to another neuron.
7. Synapse: This structure functions by permitting the entry of a neuron to move an electrical or chemical signal from one neuron to another neuron.
