Depolarization of neuron is characterized by:
Correct answer: D. None of these
- A. Na+ into the axon and K+ out of the axon
- B. K+ into the axon and Na+ out of the axon
- C. Na+ and K+ within the axon toward the axon terminal
- D. None of these

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
