Question | Answer |
---|---|
Pituitary gland | MASTER. G LAND Secretes hormones that control the functions of other glands Known as hypophysis |
Secretes Adrenocorticotropic. = hormone (ACTH) | Stimulates normal growth and development of adrenal cortex and secretions of corticosteroids |
Secretes thyroid = stimulating hormone ( TSH) | Promotes and maintain normal growth and development of the thyroid gland Stimulates Secretions of the thyroid hormones |
Anterior pituitary gland = Also called prolactin | Secretes lactogenic hormone Promotes development of breast milk during pregnancy Stimulates secretion of milk from breast after delivery of baby |
Secretes follicle = stimulating hormones (FSH) | Stimulates secretions of estrogen and production of eggs on female ovaries Stimulates production of sperm in the male testes |
Secretes luteinizing hormone ( LH) | Stimulates female ovulation and secretions of testosterone in the male |
Melanocytes = stimulating hormone (MSH) | Controls intensity of pigmentation (COLOR) in pigmented cells of the skin |
POSTERIOR Pituitary gland =. Neurohypophysis Secretes anitidiuretic hormone (ADH) | Also known as vasopressin/ decreases excretion of large amounts of urine Increases Reabsorbtion of water to renal tubules consentrates urine / increases Reabsorbtion of water by renal tubules maintaining body's water balance |
Posterior = Secretes oxytocin (OT) | Stimulates contraction of uterus during childbirth Stimulates release of milk from breasts of lactating woman In response to sucking reflex of infant To induce labor in child birth |
Pineal gland = secretes melatonin | Tiny pine cone shaped gland Regulates patterns of sleep eating and reproduction Located on dorsal aspect of midbrain region Plays a part in supporting the body's biological clock |
Thyroid gland | Located in the front of the neck just below the larynx on either side of the trachea Consists of right and left lobes |
Thyroid gland = Secretes triiodothyronine ( T3) | 3 iodine hormones Helps regulate growth and development of body Helps control metabolism and body temperature |
Thyroid gland = Secretes thyroxine (T4) | Helps maintain normal body metabolism (T3) helps (T4) |
Thyroid gland = Secretes calcitonin | Calcitonin comes from the thyroid gland Helps regulate the level of calcium in the blood |
Parathyroid glands = Secretes parathyroid hormone (PTH) | Also known as parathormone Also regulates calcium in blood |
Thymus Secretes = thymidine and thymopoietin | Stimulates (T- cells) that are involved in the immune response Large in fetus and infants Shrinks with age |
Thymus gland | Located in the mediastinum (space between the lungs) Near middle of chest / beneath the sternum |
Adrenal gland Supra renal glands | Two small glands one atop each kidney Consists of an adrenal cortex ( outer portion) and an Adrenal medulla ( inner portion) Each has independent functions / secreting different hormones |
Adrenal cortex = secretes mineralocorticoids | Regulates how minerals salts (electrolytes) are processed in the body (Aldosterone) Regulates electrolytes |
Adrenal cortex. = Secretes glucocorticoids | Sex hormones in small amounts Contribute to secondary sex characteristics in males and females Cortisone/ hydrocortisone Influences metabolism of carbohydrates/ fats/ protein in the body Necessary for maintaining normal blood pressure |
Adrenal medulla = secretes | Catecholamines / epinphRine=adrenaline Increased heart rate and force of heart muscle Dialiates bronchioles in lungs/ decreases peristalsis in intestines Raises blood pressure by causing liver to convert glycogen into glulcose |
Adrenal medulla secretes/ carecholamines | Norepinephrine = noradrenaline Also known as sympathomimetic Produces vasoconstrictor effect on the blood vessels there by raises blood pressure |
Pancreas | Elongated gland located in the upper guarantee of the abdomen Behind the stomach extends horizontally across the body |
Pancreas= islets of langerhans secretes = glucagon | Increases blood glucose levels by stimulating liver to convert glycogen into glulcose when blood sugar is extremely low |
Pancreas = islets of langerhans secretes =insulin | Allows glulcose to pass from blood through cell mambranes to be used for energy Promotes conversion of excess Gloucose into glycogen for storage in the liver for later use Lowers blood glucose levels |
Ovaries | Female sex gland= female gonads Pair of almond shaped glands Responsible for producing mature ova and releasing them at intervals during ovulation |
Ovaries = secretes | Estrogen = promotes maturation of ovum in the ovary Contributes to secondary sex characteristics changes in female with onset of puberty |
Ovaries = secretes | Progesterone = primarily responsible for changes within the uterus in anticipation of a fertilized ovum Responsible for development of maternal placenta after implantation of a fertilized ovum |
Testes= male gonads | Two small ovoid glands located in scrotum other then sperm responsible for secretions of ( androgens= male steroid hormones ) Also responsible for secondary sex characteristic that occur I male with onset Of puberty |
Acromegaly / pituitary conditions gland | AFTER PUBERTY Chronic metabolic condition characterized by the gradual Noticeable enlargement and elongation of Bones of the face Jaw and extremities Due to hypersecretion of the growth hormone |
Gigantism | BEFORE PUBERTY Accelerated abnormal growth mainly in long bones Proportional overgrowth of body's tissue DUE TO hypersecretion of humans hormone |
Diabetes insipidus | Inbalance between salt and water Deficiency in secretion of anitidiuretic hormone (ADH) by posterior pituitary Gland Characterized by large amounts of urine /sodium being secreted from the body |
Dwarfism | Congenital hypopituitarism /growth retardation of body due to deficiency Of human growth hormone |
Hypopituitarism | Complex syndrome resulting from absence or deficiency of pituitary hormones |
Cancer thyroid gland | Malignant tumor of thyroid gland Leads to dysfuction of the gland Inadequate or excessive secretion of the thyroid hormone Damaged gland |
Goiter/ simple; nontoxic | Hyperplasia excessive growth of the thyroid gland Result from deficient amount of iodine in diet Which is required for synthesis of T 3 and T 4 thyroid hormones produced By thyroid gland Increased number of cells / non cancerous It looks like a |
Graves' disease (Hyperthyroidism ) | Hypertropy of thyroid gland resulting in excessive secretion of thyroid hormone /causes extremely HIGH metabolism 1 =hyperthyroidism T3 T4 are high 2=goiter =increase in number of cells ( big thyroid ) 3=exophthalmia =unnatural protruding of the eye |
Hypothyroidism | Servere form (myxedema ) water retention in connective tissue/ puffy appearance thick tongue reduced metabolic rate Condition in which there is a SHORTAGE of thyroid hormone Cause extremely low body metabolism due to reduced usage of OXYGEN |
Thyroiditis / hashimoto's | Auto immune disease Chronic inflammation of the thyroid gland/ leading to enlargement of the thyroid gland |
Thyrotoxicosis ( thyroid storm ) | Acute sometimes fatal incident of OVERACTIVITY of the thyroid gland resulting in EXCESSIVE secretion of thyroid hormone May be complication of GRAVES DISEASE Effects your heart = go into shock |
hyperparathyroidism ( hyercalcemia) | OVERACTIVITY of any one of the parathyroid glands High levels of calcium in bones |
Hypoparathyroidism ( hypocalcemia) | DECREASED production of parathyroid hormone Nerve and muscle weakness with muscle spasms or tetany |
Addison's disease | Resulting from an autoimmune process a neoplasm infection or hemorrhage in the gland Life threatening disease due to failure of the adrenal cortex to secrete adequate mineralocorticoids and glucocorticoid |
Conn's disease ( primary MAIN aldosteronism) | 1 = condition characterized by excretion of excess amounts of aldosterone 2 =leads to increased volume of blood and hypertension 3=causes body to swell up due to the retention of extra sodium excrete extra potassium |
Cushing's syndrome | Condition of adrenal gland Cluster of symptoms occur as a result of excessive amounts of cortisol or ATCH circulating in the blood Symptoms Central obesity Round moon face Edema. hypertensions Supraclavicular fat pads ( buffalo hump) |
Pheochromocytoma | Vascular tumor of adrenal medulla causing extra production of epinephrine and norepinephrine Leads to hypertension and heart palpitations |
Virilism | Development of male SECONDARY sex characteristics in the female due to excessive secretion of adrenalocortical androgens from the adrenal cortex |
