Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Branches of a neuron that collect stimuli
A
Myelin sheath
B
Dendrites
C
Cell Body
D
None of the above
Explanation: 

Detailed explanation-1: -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-2: -The dendrites serve to receive incoming electrical signals from other neurons. Most neurons have a single axon to transmit outgoing signals.

Detailed explanation-3: -Dendrites receive and integrate signals from other neurons or from sensory stimuli, and conduct nerve impulses towards the axon or the cell body. In most neurons, the impulse is conveyed from dendrites to axon via the cell body, but in some types of unipolar neuron, the impulse does not travel via the cell body.

Detailed explanation-4: -Synapses: Dendrites receive signals from other neurons at specialized junctions called synapses. There is a small gap between two synapsed neurons, where neurotransmitters are released from one neuron to pass the signal to the next neuron.

Detailed explanation-5: -Dendritic arborization, also known as dendritic branching, is a multi-step biological process by which neurons form new dendritic trees and branches to create new synapses. Dendrites in many organisms assume different morphological patterns of branching.
