**Tropic Hormone
Adrenal medulla
Amine
One chemical signal-3 different effects in 3 different places
Thymus
Thymus-thymosin
Endorphins
Due to different transduction pathways
Short term stress- Responsible for release of (epi)nephrine "fight or flight", controlled by nervous signal
Chemical signal with atleast one amino acid
maturation of blood cells
Stimulates + lymphocytes
Block pain receptors
Targets release of another gland ie.hypothalamus to the pituitary gland
Short Answer
skip
Hypothyroidism
Stages of transcription
H) Oxytocin
FSH and LH
Oxytocin from hypothalamus
Multiple Choice
skip
Hypothalamus
Is in control of the neuroendocrine system and part of the brain
is a third eye
Over-production of hormone, lethargic
Ducted glands that secrete things into external environment, **TQ:Release substances outside of themselves into interstitial fluid
*Protein-water soluble-string of aminos, *Steroid-lipid soluble-four rings together
Two thyroid hormones t3 and t4
Chemical signal with atleast one amino acid
Under-production of thyroid-high metabolism, retardation
Help maintain blood pressure, heart rate, muscle tone, digestion, reproduction and bone/nerve development
Stimulates growth (especially bones)
Insulin (Lowers sugar level), Glucagon (raises sugar level)
Pancreas
Targets release of another gland ie.hypothalamus to the pituitary gland
Insulin (Lowers sugar level), Glucagon (raises sugar level)
thyroid
Under-production of thyroid-high metabolism, retardation
Stimulates contractions of uterus and mammary gland cells
Prolactin
thyroid
Chemical signal with atleast one amino acid
Mammary glands
Stored in pituitary
Placental (HCG), Oxytocin, Relaxin (pregnant waddle), testosterone
Cell signaling overview
1)Reception ie taste (plasma membrane) 2)Transduction-series of reactions (ie salty, sweet), 3)Response-Activation of cellular responses
Insulin (Lowers sugar level), Glucagon (raises sugar level)
Promotes retention of water in kidneys
Play a role in regulating biorhythm
