B. It prevents the neuron from heating up after an action potential. C. Neurotransmitters are synthesized in the myelin. D. Myelin has no known function. E. The voltage-gated sodium channels that underlie an action potential are located in the myelin. Rod, cone and ganglion cells are involved in which sensory system.
All sensory systems have a common plan.
A. Receptor potentials are graded. B. Sensory systems can adapt. The strength of a stimulus is encoded in the frequency of the action potentials it produces. The strength of a stimulus is encoded in the size of the action potentials it produces. E. Sensory receptors detect changes in a stimulus.
