NUR 424 Lecture Notes - Lecture 4: Furosemide, Vital Signs, Hypoparathyroidism
Document Summary
Inflammation and immune response: energy metabolism, distribution of muscle, adipose tissue, sexual development, fluid and electrolyte balance, negative feedback mechanism, range of hormones, disorders: hyperfunction; hypofunction. Influences almost every cell, organ, function of body. Glands of endocrine system: pituitary (master gland, thyroid, parathyroid located posterior to the thyroid, adrenal glands located on kidney, pancreatic islets, ovaries, testes. Function of hormones: dual regulatory system: nervous system and hormones, glands secrete hormones into bloodstream, negative feedback system. Glands inhibit or produce hormone in response to levels in bloodstream: hormone function may be tissue specific; more than one hormone may affect a specific tissue. Hormones classification: amines, amino acids have immediate reaction in blood. Thyroid hormones: peptides, polypeptides, proteins, glycoproteins act on cell surface. Growth hormones effects msk: steroids act inside the cell. Corticosteroids: fatty acid derivitives effect in the blood stream. Hormone action: chemical receptors on cell membrane. Production of cyclic adenosine monophosphate (amp) -> affects intracellular environment.
