Flashcards in Endocrine System Part 1 Deck (20):
How does the endocrine communicate and control
Hormones secreted into and circulated by the blood
Where are the organs of the endocrine system located?
Neck, cranial, thoracic, abdominal, and pelvic cavities
There are two types of glands in the body. Which type belongs to the endocrine system,
Cell that hormone binds to because it has a specific receptor for that type of cell
Production of too much hormone by disease of a gland
Too little of a hormone is produced by a gland
No steroid hormones work according to
Second messenger mechanisms
Nonsteroid hormones serve as...
Lipid soluble steroid hormones
Do not occur by the second messenger system, and can pass intact directly through the plasma membrane of the target cell
Major difference between nonsteroid and steroid hormones
Nonsteroid hormones serve as a first messenger by releasing a second messenger in a cell by binding to a receptor on the outside of the cell. A steroid hormone pass through the plasma membranes and into the nucleus where they bind to a receptor
Which triggers a dasher response, steroid or nonsteroid hormones?
The regulation of hormone levels in the blood depends on a highly specialized homeostatic mechanism called...
Positive feedback systems result in...
What is a prostaglandin?
What is the abbreviation for prostaglandins?
What are the three classes of prostaglandins?
Prostaglandin A (PHA), Prostaglandin E (PHE), and Prostaglandin F (PGF)
What do PGs influence?
Respiration, blood pressure, gastrointestinal secretions, inflammation, and the reproductive system
How do researches believe PHs regulate cells?
Influencing production of cAMP
What is the difference between prostaglandins and hormones?
They are produced by the tissue and then released into neighboring cells in that tissue whereas hormones influence and control activities of widely spread organs.
