TSH
Thyroid Stimulating Hormone -
Anteriour Pituitary
Thyroid Gland (TT)
Stimulates Production of Thyroid Hormones - Oxytocin
-
Posterior Pituitary
Uterus(TT) Mammory Gland (TT)
Causes contractions, stimulates milk production
Neurohormone -
ADH
Antidiuretic hormone -
Posterior Pituitary
Kidney (TT)
Increases absorption of water by the tubules in kidneys
Neurohormone -
TRH
Thyrotropin releasing hormone -
Hypothalamus
Anterior Pituitary (TT)
Regulates production of TSH -
FSH
Follicle Stimulating Hormone -
Anterior Pituitary
Ovary (TT)
stimulates development and maturation of follicles
Promotes maturation of sperm
Regulated by GnRH -
LH
Leutenizing hormone -
Anterior Pituitary
Gonads (TT)
Stimulates ovulation
Regulates production of testosterone in males
Regulated by GnRH -
PRL
Prolactin -
Anterior Pituitary
Mammory Gland (TT)
Stimulates mammary glands, lactation -
PRF
Prolactin releasing Factor -
Hypothalamus
Anterior Pituitary (TT)
Regulates secretion of Prolactin -
PIH
Prolactin Inhibiting Factor -
Hypothalamus
Anterior Pituitary (TT)
Regulates secretion of Prolactin -
Insulin:
Islet cells
Beta cells -
Pancreas
Liver or Muscle (TT)
Increase Glycogen Synthesis -
Gonadatropin releasing hormone
GnRH -
Hypothalamus
Anterior Pituitary (TT)
Stimulates LH and FSH Production - EPO
-
kidney
bone marrow (TT)
Increase blood oxygen -
ACTH
Adrenocorticotropin -
Anterior Pituitary
Adrenal Cortex (TT)
Stimulates secretion of cortisol -
MSH
Melanocyte Stimulating Hormone -
Intermediary Lobe
Melanocytes in skin (TT)
Skin darkening, color change - Calcitonin
-
Thyroid Gland
bone (TT)
Increase deposition of Ca+ in bone (Thus decreasing Ca+ in blood) - Parathyroid Hormone
-
paraThyroid Gland
Kidney (TT)
Stimulates reabsorption of Ca from urine, and activation of Vitamin D - Leptin
-
Adipose Tissue
Brain (TT)
Reduce Feed Intake - Hypoglycemia
- Pancreas secretes glucagon. Glucagon targets liver and converts amino acids and/or glycogen into glucose.
- Glycogenolysis
- Converting Glycogen to Glucose
- Hyperglycemia
- Beta Cells of Pancreas secrete insulin. Insulin targets liver and skeletal muscle to pull glucose from the blood and store as glycogen. In adipose tissue, the glucose is converted into fat.
- IGF-1
-
Insulin-Like Growth Factor
Binds to receptors in adipose tissue and inhibits fat synthesis - acromegaly
- excess GH in humans
- Cushings syndrome
- excess cortisol production
- Addison's Disease
- deficient cortisol production
- agonist
- compound similar to hormone, initiates same response
- antiagonist
- compound that interferes with binding to receptor
- Anti-coagulants
-
Heperin
EDTA
Citrate -
Liquid portion of blood sample
(Plasma or Serum) - 55%
- RBC portion of blood sample
-
45%
(99% of cell portion) - Body Fluid
-
60% intracellular
40% extracellular - Epinephrine
-
Adrenal Medulla
Many Targets (heart, etc.)
Increases blood pressure, heart rate, blood glucose concentration - Norepinephrine
-
Adrenal Medulla
many targets
vasoconstriction, increased heart rate, blood pressure, sugar level
Targets adipose tissue and releases stored fat - Ractopamine
- Stimulate muscle protein gain, decreased back fat, increased ADG,
