If you had a disorder that caused neurons to demyelinate, this would initially cause
A)neurons to immediately begin to die.
B)dendrites to proliferate excessively.
C)the insulation of the axon to deteriorate.
D)a decreased number of nodes of Ranvier.

Question

Quizplus · Accepted Answer

Demyelination refers to the loss or deterioration of the myelin sheath surrounding axons. The myelin sheath provides insulation and allows for efficient transmission of nerve impulses. Without this insulation, the transmission of nerve impulses is slowed down or can fail altogether. This can lead to various neurological symptoms depending on the location of the affected neurons, but typically it does not immediately cause neurons to die or stimulate dendrite proliferation. A decreased number of nodes of Ranvier (the spaces between adjacent sections of myelin along the axon) is also a potential consequence of demyelination, but this is less likely to be an initial effect.
