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: -Axons transmit signals away from the neuron whereas dendrites carry signals towards the nerve cell.

Detailed explanation-2: -A neuron sending a signal (i.e., a presynaptic neuron) releases a chemical called a neurotransmitter, which binds to a receptor on the surface of the receiving (i.e., postsynaptic) neuron. Neurotransmitters are released from presynaptic terminals, which may branch to communicate with several postsynaptic neurons.

Detailed explanation-3: -Dendrites extend out from the cell body and receive messages from other nerve cells. An axon is a long single fiber that transmits messages from the cell body to the dendrites of other neurons or to other body tissues, such as muscles.

Detailed explanation-4: -Dendrites. Dendrites are tree-like extensions at the beginning of a neuron that help increase the surface area of the cell body. These tiny protrusions receive information from other neurons and transmit electrical stimulation to the soma. Dendrites are also covered with synapses.

Detailed explanation-5: -Nerve cells (neurons) have extensive processes called dendrites. These occupy a large surface area of a neuron. They receive many signals from other neurons and contain specialized proteins that receive, process, and transfer these to the cell body.
