Chapter 17, Problem 5RC
Summary Introduction
To review:
The reason for the long-lasting effects of epinephrine and norepinephrine released by the adrenal glands as a hormone compared to when released as a neurotransmitter at the neuroeffector junctions.
Introduction:
Epinephrine and norepinephrine are basically hormones and released into the bloodstream from the adrenal medulla. They also function as neurotransmitters when released from the central nervous system (CNS). Their role is to fight response to stress.

Epilepsy is the disesae. Which areas of the brain are affected by epilpesy? What type of neurotransmitters are altered in this epilepsy? Provide neurophysiological evidence. Please talk about voltage gated K+, Na+, Ca++ and ligand channels. Tell if any of them are affected. if affected what is the consequence?Which ion channels are affected?
Unmyelinated axons conduct action potentials without decrement, but when myelinated axons lose myelin in demyelinating diseases such as multiple sclerosis, conduction of action potentials is blocked. Why?
