◉ Hypothalamus.
Answer: Located: Superior to Pituitary gland
-Directly controls the release of hormones from the pituitary gland
and indirectly controls the release of hormones from other
endocrine glands
Located: Superior to Pituitary gland
-regulatory hormones include releasing and inhibiting hormones
-ADH and Oxytocin made here
◉ Anterior Pituitary.
Answer: Made of epithelial tissue
-Receive releasing and inhibiting hormones from the Hypothalamus
-Hormones released
-Growth Hormone (GH)
-Prolactin (PRL)
-Follicle Stimulating Hormone (FSH)
-Luteinizing Hormone (LH)
-Thyroid Stimulating Hormone (TSH)
,-Adrenocorticotropic Hormone (ACTH)
◉ Posterior Pituitary.
Answer: Made of nervous tissue
Consist primarily of unmyelinated axons extending from the
hypothalamus
-Recieve nerve signals
-Hormones are synthesized by the Hypothalamus and stored in
posterior pituitary
-release hormones into the blood stream
-Hormones released:
-Oxytocin (OT)
-Antidiuretic Hormone (ADH)
◉ Growth Hormone (GH)
-Somatotropin.
Answer: Makes things bigger
-causes growth of all body tissue
-stimulates lipolysis (fat utilization for energy)
-inhibits actions of insulin on carbohydrates
-high concentrations can cause Gynecomastia (breast development)
, -stimulates the release of insulin-like growth factors (IGF)-
somatomedins) from the liver; both GH and IGFs stimulate target
cells (especially muscle) to increase protein syntheses, cell division,
and cell differentiation; liver to increase both glycogenolysis and
gluconeogenesis; and adipose connective tissue to increase lypolsis
◉ Glycogenolysis.
Answer: When blood glucose leaves drop the liver hydrolyzes some
of the glycogen into glucose and releases it in the blood
◉ Gluconeogenesis.
Answer: The process where the liver forms glucose from
noncarbohydrate sources (e.g. Fats, proteins)
◉ Glycogenesis.
Answer: The process of binding glucose monomers together to form
a polysaccharide called glycogen
◉ Glucogen.
Answer: Causes target cells in the liver to break down glycogen into
glucose and release it into the bloodstream
◉ Prolactin (PRL).
Answer: -causes production of milk
