Term
What is the general name of the types of organs that produce hormones?
Definition
Endocrine
Term
What name is given to cells or tissues receptive to hormones?
Definition
Target areas or target cells
Term
Melatonin is secreted by what gland?
Definition
Pineal gland and is associated with sleep
Term
Where is ADH stored?
Definition
Posterior Pituitary Lobe
Term
What is the effect of TSH, and where is it produced?
Definition
Produced in the anterior pituitary lobe; stimulates the thyroid gland. Secretes and produces T3 and T4, which are other thyroid hormones.
Term
What connects the two lobes of the thyroid gland?
Definition
Isthmus
Term
Does parathormone increase or decrease calcium levels in the blood?
Definition
Increase
Term
What does glucagon do as a hormone, and where is it produced?
Definition
Glucagon converts glycogen to glucose and is produced in the alpha cells that are in the pancreatic islets
Term
Which hormones in the adrenal gland control water and electrolyte balance?
Definition
Corticosteriod hormones
Term
What is the primary gland that secretes epinephrine?
Definition
Adrenal Medulla
Term
Where is growth hormone produced?
Definition
Anterior pituitary lobe
Term
What is another name for T3?
Definition
Triiodothyronine
Term
Interstitial cells produce which hormone?
Definition
Testosterone
Term
What structures are responsible for the production of estrogen?
Definition
Ovaries
Term
Endocrine System
Definition
consists of glands that produce chemical messengers called hormones
Term
Hormones
Definition
Chemical messengers that the endocrine system glands produce and are picked up by blood capillaries; this type of release is called a "ductless secretion"; Have many effects such as growth, changes and development, or maturation; metabolism; sexual development; regulation of the sexual cycle; and homeostasis
Term
target cells
Definition
Areas receptive to hormones and could be organs or tissues
Term
Pineal gland
Definition
Develops from the diencephalon of the brain and secretes the hormone melatonin
Term
Thyroid-stimulating hormone
Definition
TSH
Term
Growth hormone
Definition
GH
Term
Prolactin
Definition
PRL
Term
Follicle-stimulating hormone
Definition
FSH
Term
Luteinizing hormone
Definition
LH
Term
Adrenocorticotropin
Definition
ACTH
Term
Antidiuretic hormone
Definition
ADH
Term
Oxytocin
Definition
Stimulates the contraction of the cells of the mammary glands, resulting in the release of milk, and causes uterine contractions
Term
Follicle cells
Definition
Surround the colloid
Term
Colloid
Definition
a storage region for thyroid hormones
Term
Parafollicular cells
Definition
Which occur in the spaces between the follicles
Term
Pancreas
Definition
A mixed gland in that it has an exocrine function and an endocrine function
Term
Glucagon
Definition
Converts glycogen to glucose
Term
Alpha cells
Definition
Glucagon is produced in specialized cells that occur in clusters
Term
Pancreatic islets
Definition
specialized cells which are the alpha cells that occur in clusters
Term
Insulin
Definition
Pancreatic islets also produce this hormone that lowers the blood glucose level
Term
Beta cells
Definition
Where insulin is produced, stimulates the conversion of glucose to glycogen
Term
Delta cells
Definition
secrete somatostatin
Term
Somatostatin
Definition
secreted after the ingestion of a meal and inhibits the secretion of insulin and glucagons from the pancreas; may play a role in increasing efficiency
