Endocrine signaling Flashcards
peptides
chain of amino acids
polar
Steroids
made from cholesterol
non polar
amines
derived from Tyr or Trp and are POLAR and NON POLAR also secreted from the thyroid gland
Eicosaniods
non polar
Synergism
combined effect = more than additive
Permissivness
Second hormone only enhances effects of the first
Antagonist
actions of first hormone opposed by the second
Anterior pituitary
endocrine tissue no neural network
Posterior pituitary
Speed, Package neural hormones, connects to the blood stream, holds hormones but cannot make them
AntiDiuretic Hormone (ADH)
peptide hormone, stimulates renal water retension
Oxytocin
Peptide hormone, milk ejection and contractions during paturition,
Secondary
trophic
Trophic homones
act on another endocrine gland to secret another homone
Primary
systemic
systemic
hormone which has actual effect on the body or target tissue
