Question

If a person has Parkinson's disease, the message from a motor neuron to a leg muscle doesn't get transmitted because they lack the neurotransmitter called

Answer 1

Parkinson's disease is caused by the degeneration of dopamine neurons, resulting in symptoms such as tremors, slowed movement, and muscular rigidity. Disruptions in other neurotransmitters like serotonin, norepinephrine, and glutamate may also occur.

Step-by-step explanation:

Parkinson's disease is caused by the degeneration of neurons that release dopamine. Loss of dopamine neurons in the substantia nigra results in a reduction of dopaminergic innervation and leads to symptoms such as tremors, slowed movement, muscular rigidity, and balance problems. In addition to dopamine, recent studies suggest disruptions in other neurotransmitters such as serotonin, norepinephrine, and glutamate in Parkinson's disease patients.
