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.

affects the water bodies: excessive use of fertilizers causes eutrophication. the fertilizers which are used on plants affect the quality of land on which it is used, further causing erosion of soil. the fertilizers used on plants contain harmful chemical fumes which affect the environment.
