| neoplasms, gonadal tissue | Neoplasms composed of ovarian or testicular tissue. This concept does not refer to neoplasms located in the ovaries or testes. (12 Dec 1998) |
|---|---|
| adrenocortical hormones | Hormone's secreted by the human adrenal cortex; e.g., cortisol, aldosterone, corticosterone. (05 Mar 2000) |
| adrenomedullary hormones | Hormones produced by the adrenal medulla, particularly the catecholamines epinephrine and norepinephrine. (05 Mar 2000) |
| pancreatic hormones | Peptide hormones secreted into the blood by cells in the islets of langerhans of the pancreas. The alpha cells secrete glucagon; the beta cells secrete insulin; the delta cells secrete somatostatin; and the pp cells secrete pancreatic polypeptide. (12 Dec 1998) |
| gastrointestinal hormones | Hormones that originate in and regulate motor and secretory activity of the digestive organs. (12 Dec 1998) |
| parathyroid hormones | Polypeptide hormones (84 amino acid residues) secreted by the parathyroid glands, which promote release of calcium from bone to extracellular fluid by activating osteoblasts and inhibiting osteoclasts, indirectly promote increased intestinal absorption of calcium, and promote renal tubular reabsorption of calcium and increased renal excretion of phosphates. It is a major regulator of bone metabolism. Secretion of parathyroid hormone increases when the level of calcium in the extracellular fluid is low. Its action is opposed by calcitonin. (12 Dec 1998) |
| vertebrate hormones | Hormones synthesised in vertebrates. (05 Mar 2000) |
| glycoprotein hormones, alpha subunit | A non-covalently bound subunit of the glycoprotein hormones tsh, fsh, lh, and hcg which originates in the anterior pituitary gland and placenta. This subunit is virtually identical in structure and indistinguishable by radioimmunoassay in all of the above glycoproteins. It is present in both men and women, but is elevated in postmenopausal women and in patients with hypothyroidism, uraemia and malignant tumours. The alpha subunit may be involved directly in recognition of certain receptors. (12 Dec 1998) |
| pituitary hormone release inhibiting hormones | Polypeptide hormones produced in the hypothalamus which inhibit the release of pituitary hormones. (12 Dec 1998) |
| pituitary hormone-releasing hormones | Hormones released by one structure (e.g., the hypothalamus or the thyroid gland) that effect the secretion of hormones from the pituitary gland. (12 Dec 1998) |
| pituitary hormones | Hormones secreted by the anterior and posterior lobes of the pituitary gland and the pars intermedia, an ill-defined region between the two. Their secretion is regulated by the hypothalamus. (12 Dec 1998) |
| pituitary hormones, anterior | Protein, glycoprotein, or polypeptide hormones secreted by the anterior lobe of the pituitary gland. (12 Dec 1998) |
| pituitary hormones, posterior | Hormones released from the posterior lobe of the pituitary, including vasopressin (antidiuretic hormone) and oxytocin. They are formed in the neuronal cells of the hypothalamic nuclei and stored in nerve cell endings in the posterior pituitary (neurohypophysis). (12 Dec 1998) |
| placental hormones | Hormones produced by the placenta during pregnancy, including chorionic gonadotropin and substances having oestrogen, progestin, or adrenocorticoid activity. (12 Dec 1998) |
| cortical hormones | Steroid hormone's produced by the adrenal cortex. (05 Mar 2000) |
