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
