The Part of the Neuron That Carries Impulses Away from the Neuron

Question

The part of the neuron that carries impulses away from the neuron cell body is the
A) dendrite
B) axon
C) neurolemma
D) node of Ranvier

Accepted Answer

The axon is the long, slender projection of a neuron that carries nerve impulses away from the cell body towards other neurons, muscles, or glands. Dendrites, on the other hand, are shorter and receive incoming signals from other neurons. The neurolemma is a type of membrane that surrounds and protects nerve fibers, and the node of Ranvier is a gap in the insulation surrounding the axon where nerve impulses can jump from node to node, increasing the speed of transmission.
