Primary Pituitary Dysfunction - problem with…
The actual gland.
Secondary Pituitary Dysfunction - problem with…
hypothalamus.
What are some causes of hypopituitarism?
Tumors, severe malnutrition, head trauma, infection, surgery, aids, hypovolemic shock, etc.
Sheehan’s Syndrome - lots of blood loss during…
childbirth.
What can cause hyperpituitarism?
Adenomas (produces too much), and Hyperplasia (too much growth)
Growth Hormone directly affects tissue and cell growth - T/F?
False! It does not!
GH stimulates the liver to produce ____ which enhance growth activities of tissues and cells.
Somatomedins — IGF1
GH –> IGF1 –> Stimulates cell growth. T/F?
True
Gh, Insulin and Grehlin control blood glucose levels and hunger. T/F?
True!
GH Stimulates Fatty Acid Metabolism and Triglyceride Update and STOPS Carbohydrate and protein metabolism. T/F?
True!
In starvation, GH will use __ for food first.
Fat!
Low GH - More fat. T/F?
True!
Better GH Level, worse cholesterol. T/F?
False - with a better GH level, you’ll have better cholesterol. So Low GH, increased cholesterol!
