Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Dendrites are branching extensions of
A
neurotransmitters
B
endorphins
C
neurons
D
myelin
E
endocrine glands
Explanation: 

Detailed explanation-1: -Dendrites are tapering extensions of the neuronal cell body that collectively provide a great increase in the surface area available for synaptic inputs; the total dendritic surface area of a typical spinal cord motor neuron, for example, may be 30 or more times that of the cell body.

Detailed explanation-2: -Dendrites (from Greek déndron, “tree"), also dendrons, are branched protoplasmic extensions of a nerve cell that propagate the electrochemical stimulation received from other neural cells to the cell body, or soma, of the neuron from which the dendrites project.

Detailed explanation-3: -The dendrites, short extensions to the neurons, are the neurons’ main receptive surface. They mainly work to receive signals from other neurons, which they then transmit to the cell body.

Detailed explanation-4: -Dendrite: the bushy, branching extensions of a neuron that receive messages and conduct impulses toward the cell body. Axon: the extension of a neuron, ending in branching terminal fibers, through which messages pass to other neurons, muscles, or glands.

Detailed explanation-5: -Neurons have a large number of extensions called dendrites. They often look likes branches or spikes extending out from the cell body.
