Endocrine System Flashcards
3 groups based on chemical structures
1-amino acid derivatives
2-peptide hormones
3-lipid derivatives
What includes most hormones of the body
Peptide hormones
True or false: most hormones are a protein structure
True
What are the lipid derivatives
1-Eicosanoids
2- steroid hormones
Examples of eicosanoids (part of lipid derivatives)
-leukotrienes- secondary roles as hormones
-prostaglandins- involved primarily in coordinating local cellular activities (more of a paraceine secretion)
Steroid hormones are released by
Reproductive organs in males and females, by the cortex of the adrenal glands, and by the kidneys
Steroid hormones can be introduced into the body by what route? And why
Transdermal because they are made of phospho lipid bilayer (which is lipid derivative s are readily diffusible across bilayer)
Important paracrine factors that coordinate cellular activities in extracellular fluids
Eicosanoids (carbon ring with fatty acid side chains)
Melatonin is secreted by which gland
Pineal gland
Catecholamines include
Epinephrine -norepinephrine- dopamine and melatonin
Endocrine system primary function is
Hormone release
Hypothalamus secretes hormones involved with …
Fluid balance, smooth muscle contraction, the control of hormone secretion by the anterior pituitary gland.
Pituitary gland secretes multiple hormones that regulate
Endocrine activities of adrenal cortex, thyroid gland, reproductive organs, and a hormone that stimulates melanin production
Hypothyroidism is
Feel tired due to not making enough ATP
-this hormone can’t bind to mitochondria to increase energy production
Hypothyroidism symptoms
Not enough T3/T4 feel tired, no energy, gain weight hair brittle etc.
