Hormones of the Anterior Pituitary
This hormone targets and stimulates the thyroid gland to produce thyroid hormones.
Thyroid-Stimulating Hormone (TSH)
This hormone regulates water balance by promoting water reabsorption in the kidneys.
Antidiuretic Hormone (ADH)
What are two ways of hormone imbalance
Hypersecretion and Hyposecretion
What is the most common mechanism for homeostasis.
Negative Feedback Loop
A condition where blood glucose is too high.
Hyperglycemia
This hormone stimulates the growth of bones and muscles.
Growth Hormone (GH)
This hormone triggers uterine contractions during labor and milk ejection during breastfeeding.
Oxytocin
This is the type of feedback loop used by the anterior pituitary to regulate its own hormone release.
Negative Feedback
The hypothalamus releases what type of hormone to block the release of other hormones.
Inhibiting hormones
This condition results in enlarged extremities and facial features due to excessive growth hormone in adulthood.
Acromegaly
This hormone stimulates the adrenal cortex to produce cortisol.
Adrenocorticotropic Hormone (ACTH)
The posterior pituitary stores and releases hormones produced by this part of the brain.
Hypothalamus
These hormones are characterized by their water solubility and ability to bind to cell surface receptors.
Protein Hormones
This feedback mechanism ensures that hormone levels are tightly controlled by reducing or increasing the secretion of the hormone based on current physiological needs.
Homeostatic Feedback Regulation
This condition, characterized by a deficiency of ADH, leads to excessive thirst and large volumes of dilute urine.
Diabetes Insipidus
This hormone stimulates the growth and development of the mammary tissue, in preparation for the production of milk.
Prolactin (PRL)
This term refers to the posterior pituitary gland, which releases hormones produced by the hypothalamus.
Neurohypophysis
This second messenger is involved in many hormones' signaling pathways, amplifying that hormone and activating an enzyme.
Cyclic AMP (cAMP)
These types of hormones from the hypothalamus control the expulsion of more hormones from the anterior pituitary.
Releasing Hormones
Insufficient production of this hormone from the anterior pituitary gland results in decreased muscle mass and reduced bone density.
Growth Hormone
This hormone regulates the menstrual cycle and stimulates ovulation.
Luteinizing Hormone (LH)
The neurohypophysis releases ADH in response to signals from these hypothalamic receptors.
Osmoreceptors
These hormones are derived from cholesterol and are characterized by their ability to pass through cell membranes easily and bind to intracellular receptors.
Steroid Hormones
Why do target organ receptors respond only to certain hormones.
Because the receptors are hormone specific
Compare Diabetes Insipidus and Diabetes Mellitus
Insipidus- characterized by an imbalance of fluids in the body due to insufficient production or action of antidiuretic hormone (ADH)... has no connection to glucose
Mellitus- characterized by chronic hyperglycemia due to defects in insulin secretion, insulin action, or both.
