| Question | Answer |
|---|---|
| A group of glands that produce regulatory chemicals | endocrine system |
| Regulatory chemicals in the endocrine system | Hormones |
| The endocrine system and the ___________system work together to control and coordinate all other body systems. | Nervous system |
| The specific tissue acted on by each hormone | Target tissue |
| The cells that make up the target tissue have __________ in the plasma membrane and cytoplasm to which the hormone attaches. | Receptors |
| All hormones except those in the adrenal cortex and the sex glands fall into this category. | Amino acid compounds |
| Hormones that are produced by the adrenal cortex and the sex glands that are derived from cholesterol. "sterone" | Steroids |
| Hormone release follows this rhythmic cycle related to to a person's sleep patterns, highest before awakening. | 24 hour cycle |
| This gland is surrounded by bone except where it is connected with the brain's hypothalamus by a stalk called the infundibulum. | Pituitary gland |
| Two parts of this gland are the Anterior and posterior lobes. | Pituitary gland |
| The anterior globe is a true endocrine gland and consists of this type of tissue. | Epithelial tissue |
| Consists of axon and axon terminals of the neurons that originate in the hypothalamus. | Posterior lobe of the pituitary gland |
| These two hormones are produced in the hypothalamus and stored in the posterior pituitary. | Antidiuretic hormone (ADH) and Oxytocin |
| Promotes the reabsorption of water from the kidney tubules and decreases water excretion. | Antidiuretic hormone (ADH) |
| This hormone causes uterine contraction and trigger milk ejection from the breast. | Oxytocin |
| These secretions control the cells of the anterior lobe. | Releasing hormones |
| Releasing hormones travel to the anterior pituitary by way of this circulatory pathway. | Portal System |
| Called the master gland | Anterior Pituitary |
| Acts directly on most body tissues promoting protein manufacture that is essential for growth | Growth Hormone |
| Stimulates the thyroid gland to produce thyroid hormones. | Thyrotropin or Thyroid stimulating hormone |
| Stimulates hormone production in the cortex of the adrenal gland | Adrenocorticotropic hormone (ACTh) |
| Stimulates milk production | Prolactin |
| Stimulates the development of ovarian follicles in which egg cells mature and the development of sperm cells in the testes. | Follicle-stimulating hormone (FSH) |
| Causes ovulation in females and promotes progesterone secretion in females and testosterone secretion in males. | Luteinizing hormone (LH) |
| Classification of hormones (FSH and LH) which act on the gonads to regulate growth, development and reproductive function in both males and females. | Gonadotropins |
| Thyroid hormone levels are kept constant by negative or positive feedback? | Negative |
| Two hormones that regulate metabolism. | Thyroxine T4 and Triiodothyronine (T3). |
| Two types of hormones needed for normal growth. | Thyroid hormones and growth hormones. |
| Thyroid hormone production is under the control of ________ from the anterior pituitary. | TSH |
| Promote calcium release from bone tissue and increase the amount of calcium circulating in the bloodstream. | Parathyroid Hormone (PTH) |
| In addition to PTH, this hormone is needed for calcium balance. | Calcitriol |
| This hormone is the active form of Vitamin D | Dihydroxycholecalciferol or calcitriol |
| Produced by modification of Vit D in the liver and then the kidney when stimulated by PTH. | Calcitriol |
| Two small glands located on top of the kidneys | Adrenals |
| The inner are of the adrenal gland | Medulla |
| The outer portion of the adrenal gland | Cortex |
| Primary hormone produced by the medulla | Epinephrine |
| Responsible for fight or flight responses | Epinephrine and Norepinephrine |
| Three groups of hormones produced by the Adrenal Cortex | Glucocorticoids, Mineralocorticoids, Androgens |
| Male sex hormones | Androgens |
| Hormones important in the regulation of electrolyte balance | Mineralocorticoids |
| This group of hormones suppress inflammatory response | Glucocorticoids |
| The pancreas has two types of cells that perform different functions. | Acini and Islets ofLangerhans |
| Secrete digestive hormones | Acini |
| Specialized cells in the pancreas that diffuse in the bloodstream | Islets of Langerhans |
| The most important hormone produced by the islets | Insulin |
| Second islet hormone produced by alpha cells in the pancreas | Glucagon |
| The main androgen produced by the testes | Testosterone |
| Hormone produced by the ovaries that help to develop the female secondary sex characteristics and stimulate mammary gland production | Estrogen |
| Hormone produced by the ovaries that assist in the normal development of pregnancy. | Progesterone |
| Small flattened cone-shaped structure located posterior to the midbrain and connected to the roof of the third ventricle | Pineal gland |
| Hormone produced by the pineal gland during dark periods | Melatonin |
| Hormone that controls appetite. | Leptin |
| Hormone which stimulates red blood cell production in the bone marrow | Erythropoietin |
| Hormone produced in bone that stimulates diverse processes as bone formation in insulin secretion | Osteocalcin |
| Substance produced in the atria in response to increased filling with blood | Atrial natriuretic peptide |
| Increases sodium excretion by the kidneys and lowers blood pressure | Atrial natriuretic peptide |
| Hormone important in the maturation of white blood cells called T cells | Thyrosin |
| Produces several hormones during pregnancy, which causes changes in the uterine lining and in pregnancy. | Placenta |
| Hormone like substances derived from fatty acids. | Prostaglandins |
| Insulin and glucagon mainly influence the liver and skeletal muscles. true for false | True |
