Growth Hormone (Somatotropin) Flashcards
The growth spurt that people encounter during puberty is due to increased secretions of hormone.
Growth
In a woman that is pregnant, growth hormone release will be (stimulated/inhibited) .
INHIBITED
One of somatostatin’s actions in the anterior pituitary gland is to oppose effects of hormone.
Growth Hormone Releasing Hormone
Prolactin is (stimulated/inhibited) by somatostatin
INIHIBITED
In a person with low glucose levels, growth hormone release will be (stimulated/inhibited) .
STIMULATED
Gastrointestinal hormones such as gastrin, cholecystokinin, secretin, and motilin are (stimulated/inhibited) by somatostatin.
INIHIBITED
Growth hormone causes the production of in the liver, such as insulin-like growth factor-1, to carry out its indirect actions.
Somatomedins
Dwarfism in children is due to a deficiency in hormone.
Growth
Acromegaly in adults is due to excess levels of hormone.
Growth
Excess levels of growth hormone BEFORE puberty causes .
Gigantism
Somatostatin is secreted by (beta/delta) cells of the pancreas.
Delta
Somatostatin (stimulates/inhibits) the release of thyroid-stimulating hormone.
INHIBITS
In a person that is exercising, growth hormone release will be (stimulated/inhibited) .
STIMULATED
Growth hormone carries out its direct actions by binding to receptors in some tissues, such as the liver, adipose tissue, and skeletal muscle.
Tyrosine kinases associated receptors
Somatostatin is a (stimulatory/inhibitory) factor of growth hormone.
Inhibitory
Insulin and are both inhibited by somatostatin through paracrine action on the pancreatic alpha and beta cells.
Glucagon
In a person that is under high levels of stress, growth hormone release will be (stimulated/inhibited) .
Stimulated
hormone release from the hypothalamus stimulates the somatotrophs in the anterior pituitary gland to release growth hormone.
GHRH
Somatostatin is also called hormone.
Growth Hormone Inhibiting Hormone
In a person with high levels of estrogen or testosterone during puberty, growth hormone release will be (stimulated/inhibited) .
STIMULATED
Blood insulin levels (increase/decrease) as a consequence of growth hormone release.
INCREASE
hormone release from the hypothalamus inhibits the release of growth hormone from somatotrophs in the anterior pituitary gland.
Somatostatin
DIRECT actions of Growth Hormone
Decrease glucose uptake into cells (diabetogenic)
Increase lipolysis
Increase protein synthesis in muscle and increase lean body mass
Increase production of IGF
INDIRECT actions of GH via IGF
Increase protein synthesis in chondrocytes
Increase lineargrowth (pubertal groth spurt)
Increase protein synthesis in most organ
Increase organ size
