Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Branches of a neuron that collect stimuli and transport them to the cell body
A
cell body
B
dendrites
C
nodes of Ranvier
D
myelin sheath
Explanation: 

Detailed explanation-1: -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-2: -Dendrite – The receiving part of the neuron. Dendrites receive synaptic inputs from axons, with the sum total of dendritic inputs determining whether the neuron will fire an action potential.

Detailed explanation-3: -The dendrites carry impulses toward the cell body. The axon carries impulses away from the cell body. Axons and dendrites are sometimes called nerve fibers. A bundle of nerve fibers is called a nerve.

Detailed explanation-4: -Synapses are the contact points where one neuron communicates with another. The dendrites are covered with synapses formed by the ends of axons from other neurons. The brain is what it is because of the structural and functional properties of interconnected neurons.
