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 low blood calcium, which plays a key role in regulating the amount of ...
Parathyroid hormone (PTH), also called parathormone or parathyrin, is a peptide hormone secreted by the parathyroid glands that regulates the serum calcium concentration through its effects on bone, kidney, and intestine. [5] PTH influences bone remodeling, which is an ongoing process in which bone tissue is alternately resorbed and rebuilt ...
An abbreviated Kocher incision is made and the platysma muscle is dissected horizontally. The strap muscles are released off of the thyroid gland. Then the thyroid gland is mobilized and the parathyroid arterial blood supply is suture ligated. The entire parathyroid adenoma is identified and dissected out.
Hyperparathyroidism is an increase in parathyroid hormone (PTH) levels in the blood. [1] [4] This occurs from a disorder either within the parathyroid glands (primary hyperparathyroidism) or as response to external stimuli (secondary hyperparathyroidism). [1]
The parathyroid glands, of which there are 4–6, are found on the back of the thyroid glands, and secrete parathyroid hormone, [2] This causes an increase in blood calcium levels by targeting bone, the intestine, and the kidneys. The parathyroid hormone is the antagonist of calcitonin. Parathyroid hormone release is triggered by falling blood ...
Parathyroid chief cells (also called parathyroid principal cells or simply parathyroid cells) are the primary cell type of the parathyroid gland. They produce and secrete parathyroid hormone (PTH) in response to low calcium levels. PTH plays an important role in regulating blood calcium levels by raising the amount of calcium in the blood. [1]
Secondary hyperparathyroidism is the medical condition of excessive secretion of parathyroid hormone (PTH) by the parathyroid glands in response to hypocalcemia (low blood calcium levels), with resultant hyperplasia of these glands. This disorder is primarily seen in patients with chronic kidney failure.
Hypoparathyroidism is decreased function of the parathyroid glands with underproduction of parathyroid hormone (PTH). This can lead to low levels of calcium in the blood, often causing cramping and twitching of muscles or tetany (involuntary muscle contraction), and several other symptoms. It is a very rare disease.
