| 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) |
| gonadal hormones | Hormones having oestrogenic (female sex hormones) or androgenic (male sex hormones) activity. (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) |
| progestational hormones | A class of sex hormones associated with certain changes in the uterus and vagina during the menstrual cycle. They are necessary for the development of mammary tissue and for the maintenance of pregnancy. (12 Dec 1998) |
| progestational hormones, synthetic | Compounds obtained by chemical synthesis that possess progestational activity, but differ in structure from naturally occurring progestational hormones. (12 Dec 1998) |
| hormones | Chemical substances having a specific regulatory effect on the activity of a certain organ or organs. The term was originally applied to substances secreted by various endocrine glands and transported in the bloodstream to the target organs. It is sometimes extended to include those substances that are not produced by the endocrine glands but that have similar effects. (12 Dec 1998) |
| hormones, ectopic | Hormones released from neoplasms or cells outside the usual sources of hormones. Such hormones may be useful as tumour markers. (12 Dec 1998) |
| hormones, hormone substitutes, and hormone antagonists | A collective grouping for both naturally occurring and synthetic hormones, substitutes, and antagonists. (12 Dec 1998) |
