Question

1. with hypoparathyroidism, decreased secretion of pth results in: phosphorus decrease muscle hyperexcitability blood calcium increase reduced muscle tone 4) the inability to sleep is often caused by the lack of the pineal gland to secrete: adrenaline progesterone parathormone melatonin

Explanation:

1. Parathyroid hormone (PTH) regulates calcium and phosphorus levels. With decreased PTH in hypoparathyroidism, blood calcium decreases and phosphorus increases. Low - calcium levels lead to muscle hyperexcitability.
2. The pineal gland secretes melatonin which regulates the sleep - wake cycle. Lack of melatonin can cause sleep problems.

Answer:

1. muscle hyperexcitability
2. melatonin
