lo 6.1 - 6.3. what are the three main parts of a neuron?
dendrites, neurotransmitters, and axon hillock
cell body, dendrites, and axon
nucleus, axon, and dendrites
nucleus, mitochondria, and ribosomes
axon terminal, myelin sheath, and synapse

Explanation:

Neurons have a cell body that contains the nucleus and other organelles. Dendrites receive signals from other neurons, and the axon transmits electrical impulses away from the cell body. Neurotransmitters are chemicals, not main structural parts. The nucleus is within the cell - body, and mitochondria and ribosomes are organelles within the cell body. Myelin sheath is an insulating layer around some axons, synapse is a junction between neurons, and axon terminal is the end of an axon.

Answer:

B. Cell body, dendrites, and axon
