Neuron: Structure, Classification, And Functions

Neuron.
Answer:

Neuron Definition:

• Neuron is defined as structural and functional unit of the nervous system.

Neuron Classification:

1. Depending upon the number of poles.

• Unipolar neurons
• Bipolar neurons
• Multipolar neurons.

2. Depending upon the functions.

• Motor neurons
• Sensory neurons.

3. Depending upon length of axon.

• Golgi type I neuron – Have ong axons.
• Golgi type II neuron – Have short axons.

Neuron Structure:

• Neuron is made up of
• Nerve cell body
• Axons
• Dendrite

Neuron Functions:

• Nerve cell body – maintains functional and anatomical integrity of axon.
• Dendrite transmits impulses towards cell body.
• Axon – transmits impulses way from cell body.
