Scenario
Huntington's disease is a genetic disorder in which a gene mutation causes the production of an abnormal protein that damages cells in the brain. Symptoms typically begin with changes in personality, and reasoning. Uncoordinated and uncontrolled movements develop, such that physical abilities become limited.
-Scientists hypothesize that the abnormal protein stops vesicles from moving through the cytoskeleton. Predict the effect of this protein on the nervous system.

A) Neurotransmitters cannot reach the axon terminals to be released.
B) Receptor potentials cannot occur.
C) Cerebrospinal fluid leaks out of the brain.
D) Action potentials become smaller.
