Ch. 18 Flashcards
Inner section of each adrenal gland: secretes epinephrine and norepinephrine
Adrenal medulla
Outer section of each adrenal gland: secretes cortisol, aldosterone and sex hormones
Adrenal cortex
Located in the lower abdomen of a female: responsible for egg production and estrogen and progesterone secretion
Ovaries
Islet cells secrete hormones and enzymes as well to aid with digestion
Pancreas
Four small glands on the posterior of the thyroid gland
Parathyroid glands
Located at the base of the brain in the sells turcica
Pituitary gland
Two glands enclosed in the scrotal sac of a male: responsible for sperm production and testosterone secretion
Testes
Located in the neck on either side of trachea, secretes thyroxine, triiodothyronine, and calcitonin
Thyroid gland
Increases heart rate and blood pressure, secreted by adrenal medulla
Adrenaline (epinephrine)
Secreted by the anterior lobe of the pituitary gland- stimulates adrenal cortex
Adrenocorticotropic hormone (ACTH)
Secreted by adrenal cortex, increases salt reabsorption
Aldosterone
Male hormone secreted by the testes and to a lesser extent by the adrenal cortex
Androgen
Secreted by the posterior lobe of the pituitary gland, increases reabsorption of water by the kidney
Anti diuretic hormone (ADH)
Secreted by thyroid gland, decreases blood calcium levels
Calcitonin
Secreted by adrenal cortex, increases blood sugar- secreted in times of stress and has and anti-inflammatory effect
Cortisol
Estrogen secreted by the ovaries
Estradiol
Female hormone secreted by the ovaries and to a lesser extent by the adrenal cortex
Estrogen
Secreted by the anterior lobe of the pituitary gland, stimulates hormone secretion and egg production by the ovaries and sperm production by the testes
Follicle stimulating hormone (FSH)
Secreted by alpha islet cells of the pancreas, increases blood sugar by conversion of glycogen to glucose
Glucagon
Secreted by the anterior lobe of the pituitary gland, stimulates growth of bones and soft tissues
Growth hormone, somatotropin
Secreted by beta islet cells of pancreas, helps glucose to pass into cells,and it promotes the conversion of glucose to glycogen
Insulin
Secreted by ant love of pit gland, stimulates ovulation in females and testosterone secretion in males
Luteinizing hormone (LH)
Secreted by adrenal medulla, increases heart rate and blood pressure
Norepinephrine
Secreted by the post. Lobe of pit gland, stimulates contraction of the uterus during labor and childbirth
Oxytocin (OT)
Secreted by parathyroid glands, increases blood calcium
Parahormone (PTH)
Secreted by ovaries, prepares the uterus for pregnancy
Progesterone
Secreted by the ant lobe of pit gland, promotes milk secretion
Prolactin (PRL)
Male hormone secreted by testes
Testosterone
Secreted by ant lobe of pit gland, acts on thyroid gland to promote its functioning
Thyroid-stimulating hormone (TSH), thyrotropin
Secreted by the thyroid gland, increases metabolism in cells
Thyroxine (T4)
Secreted by thyroid gland, increases metabolism in cells
Triiodothyronine (T3)
Secrete by post. Lobe of pit. Gland, increases water reabsorption and raises blood pressure
Vasopressin
Hormones derived from an aa and secreted by adrenal medulla
Catecholamines
Hormones produced by the adrenal cortex
Corticosteroids
Mineral salt found in the blood and tissues and necessary for proper functioning of cells
Electrolyte
Steroid hormone secreted by he adrenal cortex, regulates glucose, fat, and protein metabolism
Glucocorticoid
Tendency of an organism to maintain a constant internal environment
Homeostasis
Substance secreted by an endocrine gland, that travels through the blood to a distant organ or gland where it influences the structure or function of that organ or gland
Hormone
Region of the brain lying below the thalamus and above the pit gland, secretes releasing factors and hormones that affect the pit gland
Hypothalamus
Steroid hormone secreted by the adrenal cortex to regulate mineral salts and water balance in the body
Mineralocorticoid
Cellular or nuclear protein that binds to a hormone so that a response can be elicited
Receptor
Cavity in the skull that contains the pit gland
Sells turcica
Steroids produced by the adrenal cortex to influence male and female sexual characteristics
Sex hormones
Complex substance related to fats and of which many hormones are made
Steroid
Pertaining to mimicking or copying the effect of the sympathetic nervous system
Sympathmimetic
Cells of an organ that are affected or stimulated by specific hormones
