Question

part #3 in the image =
myelin sheath
dendrites
axon
terminals
cell body

Explanation:

To determine the structure labeled as #3 in the neuron diagram, we analyze the options:

• Myelin sheath: Insulates axons, not the branched structure near the cell body.
• Dendrites: Branch-like structures that receive signals, matching the branched part near the neuron's cell body (labeled #3).
• Axon: Long, slender projection for signal transmission, not branched near the cell body.
• Terminals: At the end of axons/dendrites, not the main branched structure.
• Cell body: Contains nucleus, not the branched projections.

So, the correct structure for #3 is Dendrites.

Answer:

B. Dendrites
