Gastric chief cells are in the digestive system. They release pepsinogen which is a digestive enzyme that when activated by hydrochloric acid turns into pepsin and helps in the digestion of proteins.
Chief cells may also refer to parathyroid chief cells which produce and secrete parathyroid hormone when stimulated by low levels of calcium.

What is the secretary cell of parathyroid gland?
The secrotory cells of the parathyroid gland have the ability release chemicals, for example, the chief cells which secretes the parathyroid hormone.
What cells in the parathyroid gland secretes Parathyroid hormone?
The parathyroid glands release the parathyroid hormone, also known as parathormone. The parathyroid glands are four tiny masses of gland tissue located on the posterior surface of the thyroid gland. Each gland is about the size of an apple seed.
Does the thyroid contain parathyroid cells?
No, the thyroid and parathyroid are two separate glands located in the neck. The parathyroid glands are small glands located behind the thyroid gland and are responsible for regulating calcium levels in the body.
How are chief cells activated?
Gastric chief cells (as opposed to the chief cells present in the parathyroid gland) are the zymogen cells in the stomach that release pepsinogen (a precursor (zymogen) of pepsin). Without stimulation chief cells normally secrete pepsinogen at about 20% of the maximum ability. ACh (released by nerves) is the most important pathway for gastric chief cell activation. ACh also stimulates parietal cells, which secrete HCl (stomach acid). The fall in pH causes a reflex which further stimulates chief cells. Alternatively, acid in the duodenum (the first portion of the small intestine), stimulates release of secretin from S cells of the small and large intestine. Secretin also activates gastric chief cells.
True or false Glucagon is a peptide hormone that is produced in the parathyroid gland?
False. Glucagon is a peptide hormone produced by the alpha cells of the pancreas, not in the parathyroid gland. The parathyroid gland is responsible for producing parathyroid hormone (PTH), which plays a role in regulating calcium levels in the body.
What is the secretary cell of parathyroid gland?
The secrotory cells of the parathyroid gland have the ability release chemicals, for example, the chief cells which secretes the parathyroid hormone.
What hormones produce the chief cells of the parathyroid?
PTH
Which gland secretes parathormone?
Parathyroid chief cells secretes parathormone.
What cells in the parathyroid gland secretes Parathyroid hormone?
The parathyroid glands release the parathyroid hormone, also known as parathormone. The parathyroid glands are four tiny masses of gland tissue located on the posterior surface of the thyroid gland. Each gland is about the size of an apple seed.
What gland secretes pth?
Parathyroid hormone (PTH), parathormone or parathyrin, is secreted by the chief cells of the Parathyroid Glands as a Polypeptide containing 84 amino acids.Basically these glands are present behind the thyroid gland and varies in number. The main function of PTH is to increase Blood Ca2+ level.
What is the chief function of hemosiderin?
Haemosiderin is a wear and tear pigment of the cells. It has no function of its on as such it colors the tissue yellow can signify ageing of the cells.
What is chief function of hemosiderin?

Which organ has the chief function of production of lymphocytes and plasma cells?
The Spleen
What is the function parathyroid?
Calcium/phosphate balance.
Does the thyroid contain parathyroid cells?
No, the thyroid and parathyroid are two separate glands located in the neck. The parathyroid glands are small glands located behind the thyroid gland and are responsible for regulating calcium levels in the body.
What hormones released by parathyroid gland?
The parathyroid gland releases parathyroid hormone (PTH), which helps regulate calcium levels in the blood. PTH works to increase levels of calcium by promoting its release from bones, reabsorption in the kidneys, and absorption in the intestines.
The primary function of the parathyroid glands is to regulate?
calcium
