Degeneration of the dopamine-releasing neurons of the ________ is the ultimate cause of Parkinson's disease. Degeneration of the

slavikrds [6]

Answer:

a. substantia nigra

b. substantia nigra (it is repeated)

Explanation:

Parkinson's disease is a neurodegenerative disease that is caused by the death of neurons that release the neurotransmitter dopamine in the substantia nigra, or locus niger, -a region of the brain that regulates brain circuits that give the 'orders' to initiate voluntary movements- .

The lack of this neurotransmitter leads to the occurrence of the main symptoms suffered by patients: decreased movements, muscle stiffness, postural instability and tremor. These failures are generated by the abnormal way in which neurons work in the absence of dopamine through a mechanism that is not known in depth.

It is the second most frequent neurodegenerative disease, after Alzheimer's disease, with a prevalence of 2% in people over 65 years. The characteristic symptoms of stiffness, bradykinesia and tremor are associated with losses of neurons in the substantia nigra and dopamine depletion in the striatum. There are large cytoplasmic inclusions, called Lewy bodies, which are the pathological mark of the disease and appear predominantly in neurons that contain melanin of the nigra substance. Genetic studies in a subgroup of families with Parkinson's disease with autosomal dominant inheritance found a locus on chromosome 4q-21 23 and a mutation in the gene that encodes a synaptic protein, α-synuclein.

The Smiths went to dinner at Cheesecake Factory and their bill was $123.75 plus 7.5% sales tax. What is the total bill? Round to

Vikentia [17]

The total bill that was given to the Smiths at the Cheesecake factory was $133.03

An equation is an expression used to show the relationship between two or more numbers and variables.

Given that the Smiths bill was $123.75 plus 7.5% sales tax. Hence:

Total bill = $123.75 + Sales tax

Sales tax = 7.5% of bill = 0.075 * $123.75 = $9.28

Total bill = $123.75 + $9.28 = $133.03

The total bill that was given to the Smiths at the Cheesecake factory was $133.03
