Development of neurofibrillary tangles in the CNS

Question 1

Insulin is used to treat hyperkalemia because it:

stimulates sodium to be removed from the cell in exchange for potassium.

binds to potassium to remove it through the kidneys.

transports potassium from the blood to the cell along with glucose.

breaks down the chemical components of potassium, causing it to be no longer effective.

Question 2

What is the central component of the pathogenic model of multiple sclerosis?

Myelination of nerve fibers in the peripheral nervous system (PNS)

Demyelination of nerve fibers in the CNS

Development of neurofibrillary tangles in the CNS
