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 |
