The Endocrine System Flashcards
What endocrine glands are located in the neck and anterior surface of the trachea?
Thyroid and parathyroid glands
What endocrine glands are located on the superior surface of the kidney?
Adrenal glands
What gland is located on the abdominopelvic region?
Pancreas
What are the functions of the endocrine system?
Chemical composition in volume of interstitial fluid, metabolism and energy balance, contraction of smooth/ cardiac muscle, glandular secretions, operation of reproductive systems, control growth and development
What does the endocrine system consist of?
Endocrine glands and secreting cells in organs
What do hormones do?
Diffuse from interstitial fluid to bloodstream and eventually to other cells called target cells
What does ‘site specific’ mean?
Glands that only except one type of hormone
What are specific receptors?
Proteins or glycoproteins
What are the two types of hormones?
Non-steroid and steroid
Are non-steroid hormones water soluble or lipid soluble?
Water soluble
Are steroid proteins are water soluble or lipid soluble?
Lipid soluble
What endocrine Glands are located in the brain?
Hypothalamus, pineal gland, pituitary
Name examples of non-steroid hormones.
Amines, peptides, proteins, glycoproteins
Name examples of steroid hormones.
Steroid hormones, thyroid hormones, nitric oxide(NO)
What are steroid hormones transported in the blood by?
Transport proteins
How do steroid hormones get to their target cell
They diffuse through the cell membrane( lipid bilayer) and bind to receptors within the target cell
What are all steroid hormones derived from?
Cholesterol
What hormone takes longer to act and has longer effects?
Steroid hormones
