Question

Electrical pulses produced by neurons travel along specialized extensions called:

Answer 1

Axon.

Explanation:

• Neurons have three parts namely, a cell body(perikaryon), dendrites and axon.
• Axon is the thin tapering long process that conduct nerve impulses away from the cell body towards succeeding neurons or target organs.
• Axons are covered by a protective myelin sheath that provides insulation to nerve fibres.
• The myelin sheath are interrupted by small gaps called Nodes of Ranvier.
• The Nerve impulse travels from one node to another.
