Question

Please answer both in detail and with great explanation, thanks!

A.) Ordinarily, patients with advanced Parkinson’s disease (who have damage to dopamine-releasing axons) move very slowly, if at all. However, during an emergency (e.g., a fire in the building), they may move rapidly and vigorously. Suggest a possible explanation.

B.) Drugs that block dopamine synapses tend to impair or slow limb movements. However, after people have taken such drugs for a long time, some experience involuntary twitches or tremors in their muscles. Based on material in this chapter, propose a possible explanation.

Answer 1

A) Patients with advanced parkinsons moves slowly due to motor controlled abnormalities but during emergencies they may move faster than normal because of the sensory motor activity which have some signal inputs to move fast to save themselves. As the inputs got received by the brain it activates the power within them to move fast temporarily.

B) When dopamine are blocked by the drugs that creates a synapses i.e. a gap between the nerves and thus the neurotransmitter does ,nt work properly. With a very low neurotransmitter activity movements as responds by the body is very very slow.
