Question: Which structural characteristics of neurons make them suitable for the transmission of nerve impulse?
Neurons are specialized cells that are uniquely suited for transmitting nerve impulses due to their structural characteristics. Three important structural features that enable neurons to transmit nerve impulses are:-
1. Dendrites: These are short, branching extensions that receive signals from other neurons or sensory receptors and transmit them toward the cell body.
2. Axon: This is a long, slender extension of the neuron that carries nerve impulses away from the cell body and toward other neurons or effectors.
3. Myelin Sheath: This is a fatty, insulating layer that surrounds and protects the axon, allowing nerve impulses to travel more quickly and efficiently. The myelin sheath is formed by specialized glial cells called Schwann cells in the peripheral nervous system, and oligodendrocytes in the central nervous system.
