Cortex, adrenal: The outer portion of the adrenal gland located on top of each kidney. The adrenal cortex produces steroid hormones which regulate carbohydrate and fat metabolism and mineralocorticoid hormones which regulate salt and water balance in the body.
Underfunction of the adrenal cortex results in Addison disease while overfunction occurs in the adrenogenital syndrome and in Cushing syndrome.
the glucocorticoids, which are produced in reaction to stress and also help in the metabolism of fats, carbohydrates, and proteins; and the mineralocorticoids, which regulate the balance of salt and water within the body.
- Corticosteroid allergy
Corticosteroid allergy: A delayed allergic reaction to corticosteroid (drugs similar to cortisone). This occurs in 1-4% of people who use corticosteroids for asthma or other allergic diseases. A positive patch test to a corticosteroid means the patient cannot use that particular steroid. Although cross allergy between corticosteroids is common, such patients usually can tolerate another […]
- Corticotropin-releasing hormone
Corticotropin-releasing hormone: A hormone made by the hypothalamus that stimulates the release of corticotropin by the anterior pituitary gland. Corticotropin-releasing hormone is abbreviated and often referred to as CRH. CRH is chemically classed as a neuropeptide hormone — a protein-like molecule made up of a short chain of amino acids produced in the brain that […]
Cortisol: A metabolite of the primary stress hormone cortisone. Cortisol is an essential factor in the proper metabolism of starches, and it is the major natural glucocorticoid (GC) in humans.
Cosmid: DNA from a bacterial virus into which is spliced a small fragment of a genome to be amplified and sequenced. A cosmid is an artificially constructed structure. It is used in cloning (copying) pieces of DNA. (On a technical level, a cosmid contains the cos gene of phage lambda and can be packaged in […]
