Question

Write difference between axon and dendron?​

Answer 1

Answer:

Axon and dendrite are two components of nerve cells. Nerve cells are the structural and functional units of the nervous system of animals. They transmit nerve impulses to the brain, spinal cord, and to the body to coordinate the functions of the body. An axon is a long conical prolongation of the cell body of the nerve cell. Every nerve cell has an axon. The short structures that extend from the cell body are called dendrites. A single nerve cell has many dendrites. The main difference between axon and dendrite is that axon carries nerve impulses away from the cell body whereas dendrites carry nerve impulses from synapses to the cell body.

Answer 2

Axon-

• It is found always single in number.

• Neurofibrils are present in the axon.

• Nissl's granules are absent in this.

• Generally the size of the axon is long compared to the dendron.

• The transmit the nerve impulses away from the body.

• Covering of the axon is known as axolemma.

• The liquid present in the axon is known as axoplasm.

• They contains mitochondria as well.

Dendron-

• Dendron may be present single it also may more than one in number.

• Neurofibrils are also present in this.

• The transmission of the nerve impulse in dendron is towards the cell body.

• They are smaller than axon usually.

• Nissl's granules are present in the Dendron.

• They do not have mitchondria.
