Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
long extension of neuron that sends information
A
dendrite
B
cell body
C
axon
D
nodes of Ranvier
Explanation: 

Detailed explanation-1: -The long extension from cyton/cell body /soma of a neuron is called axon. A cyton may give rise to many dendrites but never more than one axon. The function of the axon is to transmit information to different neurons, muscles and glands.

Detailed explanation-2: -Dendrite. Dendrites are the extensions that are associated with the cell body of the neuron. These dendrites are structures that are part of the synapse from where the impulse from the previous neuron enters a specific neuron.

Detailed explanation-3: -Neurons are specialized cells that receive and send signals to other cells through fragile and thin cellular extensions called axons. These axons extend over distances long and short to reach their target, ultimately connecting neurons with other nerve tissue, muscle tissue, or sensory organs (Figure 1A).
