Verified
What are three basic components of most neurons
A) vesicles, terminal buttons, synapses
B) myelin, nodes, axon terminals
C) cell body, axon, dendrites
D) hindbrain, midbrain, forebrain
Neurons
Neurons are the basic working units of the brain and nervous system, responsible for receiving, processing, and transmitting information through electrical and chemical signals.
Cell Body
The spherical part of a neuron that contains the nucleus and connects to the dendrites and axon, critical for processing information.
Axon
A long, slender projection of a neuron that conducts electrical impulses away from the neuron's cell body to other neurons, muscles, or glands.

Final Answer :
C
Explanation :
The three basic components of most neurons are the cell body, axon, and dendrites. The cell body contains the nucleus and other organelles. The dendrites receive signals from other neurons and transmit them to the cell body. The axon transmits signals away from the cell body to other neurons or muscles. Choice A is incorrect because vesicles and terminal buttons are parts of the synapse, which is where the signal is transmitted between neurons. Choice B is incorrect because myelin and nodes are specialized parts of the axon found in some, but not all, neurons. Choice D is incorrect because the hindbrain, midbrain, and forebrain are three major divisions of the brain, not components of individual neurons.
