Which of the following glands increases blood calcium levels? A) thyroidB) adrenalC) parathyroidD) pituitary
Parathyroid glands are small endocrine glands in the neck of humans and other tetrapods. Humans usually have four parathyroid glands located on the back of the thyroid gland in variable locations. The parathyroid gland produces and secretes parathyroid hormone in response to a low blood calcium which plays a key role in regulating the amount of calcium in the blood and within the bones. Parathyroid …

This occurs from a disorder either within the parathyroid glands (primary hyperparathyroidism) or outside the parathyroid glands (secondary hyperparathyroidism). Symptoms of hyperparathyroidism are caused by inappropriately normal or elevated blood calcium leaving the bones and flowing into the blood …

Parathyroid gland - Wikipedia
The parathyroid gland is located beside the thyroid gland in the neck below and in front of the larynx and above the trachea. It is composed of four glands in total that monitor blood calcium levels via the calcium sensing receptors a g-coupled protein receptor. The parathyroid glands main role is calcium homeostasis.
The parathyroid glands of which there are 4–6 are found on the back of the thyroid glands and secrete parathyroid hormone This causes an increase in blood calcium levels by targeting bone the intestine and the kidneys. The parathyroid hormone is the antagonist of calcitonin.
The hypothalamic–pituitary–adrenal axis (HPA axis or HTPA axis) is a complex set of direct influences and feedback interactions among three components: the hypothalamus the pituitary gland (a pea-shaped structure located below the thalamus) and the adrenal (also called "suprarenal") glands (small conical organs on top of the kidneys)..
