Endocrine gland cretinism in infants and myxoedema in adults. Hyperparathyroidism results in hypercalcaemia and its effects and in extreme bone wasting. Hypoparathyroidism leads to hypocalcaemia, evidenced by tetany seizure and respiratory paralysis. Hyposecretion of insulin results in diabetes mellitus; cardinal signs are polyuria, polydipsia, and polyphagia. Endocrine gland Endocrine glands are glands of the endocrine system that secrete their products, hormones, directly into the blood rather than through a duct. The major glands of the endocrine system include the pineal gland, pituitary gland, pancreas, ovaries, testes, thyroid gland, parathyroid gland, hypothalamus and adrenal glands. The hypothalamus and pituitary gland are neuroendocrine organs.
Hypobranchial gland hypobranchial glands are referred to as "mucus tracts" and occupy a posterior position in the body. There have been studies on some species within the family Muricidae, because in those species this gland secretes the precursor to the historically important natural dye, Tyrian purple. It is thought that the compounds in hypobranchial secretions may also have interesting pharmacological properties. Hypobranchial gland The hypobranchial gland is a glandular structure which is part of the anatomy of many mollusks, including several different families of gastropods, and also many protobranch bivalves. This gland produces mucus as well as biologically active compounds. The cephalopod
