Increase blood sugar
Anti inflammatory
Aldosterone
Regulars blood volume
Catecholamines
Epinephrine and norepinephrine
FSH
Sperm and follicles
LH
Testes and Ovulation
Negative Feedback
Hypothalamus
Pituitary
Target cells
Proteins and polypeptides
Majority of hormones Water soluble Can not travel in cell Receptor on cell 2nd messenger
Steroids
Lipids
Receptors inside cell
Primary messenger
Affects transcription/translation
Adrenal cortex and Gonads produce what
Steroids
Tyrosine derivatives
From tyrosine (amino acid)
2nd Messengers
- Hormone
- Receptor
- G Protein (GDP to GTP)
- Adenylate cyclase (ATP to cAMP)
- cAMP actives Protein
Primary messenger
Steroids and thyroid hormones
(Lipid based)
- Hormone crosses membrane
- Receptor
- Transcription and Translation
Thyroid and steroid
Lipid based
Primary Messenger
Hypothalamus
True master gland/Control Center
