What effect do demyelinating disorders such as multiple sclerosis have on neurotransmission? a. increased rate of action potential conduction b. slower rate of action potential conduction c. facilitation of action potential initiation d. faster rate of repolarization

Option B

Explanation:

Multiple sclerosis can cause a variety of symptoms, which includes change in sensation, muscle weakness, depression, loss of coordination, pain and fatigue.

It can also cause impaired mobility and disability in severe cases. It affects the brain cells (neurons) of the brain and spinal chord which helps in the control and coordination to carry information.

This disease gradually destructs the myelin sheet( demylenation) of neurons axis throughout the brain and spinal cord. This sowers down the rate of action potential conduction.
