Source of Secretion
This hormone is secreted by somatotropin of the anterior pituitary
What is growth hormone?
The thirst center in hypothalamus, kidneys, and blood vessels are targets for this hormone
ADH
GHRH, time of day, age, stress, and nutrient levels are all stimuli for this hormone
What is growth hormone
How is secretion for ADH stopped?
Negative Feedback, hydration
Reducing calcium levels in blood by inhibiting osteoclast activity in bone and stimulating kidneys to increase loss of calcium in urine are functions of what hormone?
What is calcitonin?
This hormone is produced by supraoptic nuclei and released from the posterior pituitary
What is antidiuretic hormone (ADH)
What is the target cells of growth hormone
Nearly all cells and liver
TSH, cold weather, pregnancy, high altitude, and hypoglycemia stimulate release of this hormone
T3/T4
How is oxytocin stopped?
Removal of stimulus
Maintaining fluid balance, blood volume, and bp. Kidneys decrease urine output, thirst center increase intake fluid, and vasoconstriction are all functions of this hormone
What is ADH?
What cells are oxytocin produced by and what gland are they secreted from
What is paraventricular nuclei and posterior pituitary
Smooth muscle of uterus and breast are targets for this hormone
Oxytocin
Increased blood solute concentration is a stimulus for release of this hormone
What is ADH?
How is secretion of T3/T4 stopped?
High levels of TH which inhibit TSH and TRH
Promotion of: glycogenolysis, gluconeogenesis , and lipolysis. Inhibition of glycogenesis and lipogenesis. Release of IGFs and stimulating protein synthesis, cell division and differentiation are all functions of this hormone.
What is growth hormone
Follicular cells of thyroid release these hormones
T3/T4
List the targets of thyroid hormone
All cells, Neurons, liver, adipose, lungs, and heart
What is the stimulus for release of oxytocin?
Baby pushing on cervix and suckling of breast
What stops the secretion of growth hormone
GHIH, decreased GHRH, High levels of GH
Describe the functions of oxytocin in females and males
Females: more frequent contractions which help deliver baby. Milk ejection.
Males- Help improve mood, lower stress hormones, reduce bp, and increase pain tolerance
Where is calcitonin secreted from
Parafollicular cells
What are the targets for calcitonin
Osteoclasts and kidneys
Joe has a high amount of Ca in his blood because he drinks four glasses of milk before his daily workout. What protein is Joe secreting a lot of most likely?
Calcitonin
An olympic athlete comes into the doctor office with abnormally high Calcium levels. The doctor tells her to take a break from exercise and to monitor her calcium levels. Once her calcium levels reach a normal state, what hormone stops secretion?
Calcitonin
Explain ALL the functions of thyroid hormone
Increase metabolism and release nutrients in blood. Uptake of amino acids, glucose, and increase mitochondrial enzymes. Addition of sodium and potassium pumps. Increase in glycogenolysis, gluconeogenesis, and lipoltys. Decrease glycogenesis and lipogenesis. Increased respiration rate and heart rate and force of contraction
