Chap 18, Endocrine System, Major Endocrine Glands: The hormones Flashcards
Major Endocrine Glands: The hormones they produce and their actions
Thyroid Hormones
Thyroxine (T4); triiodothyronine (T3); Calcitonin
Thyroid Hormones: Thyroxine or tetraiodothyronine (T4) and Triiodothyronine (T3)
Increases metabolism in body cells
Thyroid hormone: Calcitonin
Decreases blood calcium
Parathyroids Hormone
Parathyroid hormone or parathormone (PTH)
Parathyroids hormone: Parathyroid hormone or parathormone (PTH)
Increases blood calcium
Adrenal Cortex Hormones
Cortisol (glucocorticoid), Aldosterone (mineralocorticoid), Androgens, Estrogens (sex hormones)
Adrenal Cortex Hormone: Cortisol (glucocorticoid)
Increases blood sugar
Adrenal Cortex Hormone: Aldosterone (mineralocorticoid)
Increases reabsorption of sodium
Adrenal Cortex Hormone: Androgens (sex hormone)
Secondary sex characteristics
Adrenal Cortex Hormone: Estrogens (sex hormone)
Secondary sex characteristics
Adrenal Medulla Hormones
Epinephrine (adrenaline), Norepinephrine (noradrenaline)
Adrenal Medulla Hormone: Epinephrine (adrenaline)
Sympathomimetic: it raises blood pressure and heart rate and dilates airways.
Adrenal Medulla Hormone: Norepinephrine (noradrenaline)
Sympathomimetic: it raises blood pressure and heart rate and dilates airways.
Pancreas, Islet Cells Hormones
Insulin, Glucagon
Pancreas, Islet Cells Hormone: Insulin
Decreases blood sugar (glucose to glycogen)
Pancreas, Islet Cells Hormone: Glucagon
Increases blood sugar (glycogen to glucose)
Anterior Pituitary Lobe (Adenohypophysis) Hormones
Growth hormone (GH) (somatotropin); Thyroid-stimulating hormone (TSH); Adrenocorticotropic hormone (ACTH); Gonadotropins: Follicle-stimulating hormone (FSH), Luteinizing hormone (LH); Prolactin (PRL)
Adenohypophysis Hormone: Growth hormone (GH) (somatotropin)
Increases bone and tissue growth
Adenohypophysis Hormone: Thyroid-stimulating hormone (TSH)
Stimulates thyroid gland and thyroxine secretion
Adenohypophysis Hormone: Adrenocorticotropic hormone (ACTH)
Stimulates adrenal cortex, especially cortisol secretion
Adenohypophysis Hormone: Gonadotropins: Follicle-stimulating hormone (FSH)
Oogenesis and spermatogenesis
Adenohypophysis Hormone: Luteinizing hormone (LH)
Promotes ovulation; testosterone secretion
Adenohypophysis Hormone: Prolactin (PRL)
Promotes growth of breast tissue and milk secretion
Posterior Pituitary Lobe (neurohypophysis) Hormones
Antidiuretic hormone (ADH) (vasopressin); oxytocin
Neurohypophysis Hormone: Antidiuretic hormone (ADH) (vasopressin)
Stimulates reabsorption of water by kidney tubules
Neurohypophysis Hormone: oxytocin
Stimulates contraction of the uterus during labor and childbirth
Ovary Hormones
Estrogens, Progesterone
Ovary Hormone: Estrogens (estradiol and estrone)
Promote development of ova and female secondary sex characteristics
Ovary Hormone: Progesterone
Prepares and maintains the uterus in pregnancy
Testes Hormones
Testosterone
Testes Hormone: testosterone
Promotes development of sperm and male secondary sex characteristics
