The Correct Answer is D
Alzheimer disease is a progressive neurodegenerative disorder that affects memory, cognition, behavior, and daily functioning. Alzheimer disease is characterized by the accumulation of amyloid-beta plaques and neurofibrillary tangles in the brain, which impair the communication and survival of neurons. Alzheimer disease is influenced by genetic and environmental factors, and some rare forms of the disease are caused by mutations in specific genes.

Correct Answer is B
Explanation
Parathyroid hormone (PTH) is a hormone produced by the parathyroid glands, which are located behind the thyroid gland in the neck. PTH regulates the calcium levels in the blood by stimulating the release of calcium from the bones, increasing the absorption of calcium from the intestines, and decreasing the excretion of calcium from the kidneys. When the calcium levels in the blood are low, PTH is secreted to raise them back to normal.
Correct Answer is A
Explanation
Cushing syndrome is a condition that occurs when the body is exposed to high levels of cortisol, a hormone produced by the adrenal glands. Cortisol helps regulate metabolism, blood pressure, immune function, and stress response.
However, excess cortisol can cause various problems, such as weight gain, moon face (round and puffy face), buffalo hump (fat accumulation on the upper back), purple striae (stretch marks), irregular periods, weakness, emotional changes, and easy bruising. One of the causes of Cushing syndrome is the overproduction of ACTH by the pituitary gland, which stimulates the adrenal glands to produce more cortisol.
