Answer #1

(c) dopamine

Parkinsonism is caused by degenerations of neurons in neural structure tract that are basically dopaminergic. This basal ganglion controls muscle tones and coordinates movements. associate imbalance is caused by deficiency of Intropin (an repressing neurotransmitter) vis a vis. vasoconstrictive (cholinergic that is associate excitant neurotransmitter) leads to motor deficits.

Hence to revive a balance central anticholinergics are given. Parkinson’s malady may be a clinical image characterised by tremor, rigidity, slowness of movement, and bodily property instability. the most common symptom is tremor, which regularly affects one hand, spreading 1st to the leg on constant aspect then to the opposite limbs.

The patient has associate uncommunicative face, associate unmodulated voice, associate increasing tendency to stoop, and a shuffling walk.

Huntington's disease is caused by a single dominant allele and results in progressive mental and neurological damage. The disease usually becomes symptomatic when a person is between 30 and 50 years old and the patient usually dies within 15 years of diagnosis. Approximately 1 in 25,000 Caucasians have this disease. Huntington's disease has not been associated with any other disease, now or in the past. Why might natural selection not have eliminated such a deleterious allele from the population? Select...
