Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
____ send signals away from neurons whereas ____ receive signals from other neurons.
A
dendrites; axons
B
axons; dendrites
C
synapses; dendrites
D
axons; synapses
Explanation: 

Detailed explanation-1: -In a neuron or a nerve cell, the impulse travels through the axon towards the axonite. The dendrite of the receiving neuron picks up this impulse which is again transferred to another neuron or a cell. Hence, axon transfers the signal/impulse and the dendrite receives the impulse from other neurons.

Detailed explanation-2: -An axon, or nerve fibre, is a long slender projection of a nerve cell, or neuron, that conducts electrical impulses away from the neuron’s cell body or soma.

Detailed explanation-3: -Dendrites are the protoplasmic projections of a nerve cell that transmit signals towards the cell body. Dendrites receive information in the form of electrochemical signals from the other neurons through the synapses and transmit the signals towards the cell body or soma.
