NEUROTRANSMISSION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What part of the neuron has bushy, branching extensions that receive and integrate messages, conducting impulses toward the cell body?
A
Synapse
B
Axon
C
Myelin Sheath
D
Dendrite
Explanation: 

Detailed explanation-1: -Structure of a neuron. At one end of the cell body (and indeed, around most of its periphery) are many small, branching protrusions called dendrites.

Detailed explanation-2: -Dendrite-bushy, branching extensions of a neuron that receives messages and conduct impulses toward cell body.

Detailed explanation-3: -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.

Detailed explanation-4: -A dendrite (tree branch) is where a neuron receives input from other cells. Dendrites branch as they move towards their tips, just like tree branches do, and they even have leaf-like structures on them called spines.

Detailed explanation-5: -An axon typically develops side branches called axon collaterals, so that one neuron can send information to several others. These collaterals, just like the roots of a tree, split into smaller extensions called terminal branches. Each of these has a synaptic terminal on the tip.
