The secrotory cells of the parathyroid gland have the ability release chemicals, for example, the chief cells which secretes the parathyroid hormone.

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.

PTH

Parathyroid chief cells secretes parathormone.

A parathyroid scan is sometimes called a parathyroid localization scan or parathyroid scintigraphy.
