•A common feature in the control of hormone release is a feedback loop connecting the response to the initial stimulus. This loop is called _______, which regulates virtually all hormonal pathways and functions to maintain a “constant” internal environment. This called _______.
• A common feature in the control of hormone release is a feedback loop connecting the response to the initial stimulus. “Negative feedback” regulates virtually all hormonal pathways and functions to maintain a “constant” internal environment. This called Homeostasis.

14A high level of blood glucose triggers ______(hormone) release from the ______(gland). This hormone promotes the uptake of ______ and the synthesis of _______.
A low level of blood glucose triggers_____(hormone) release from the ______(gland). This hormone promotes the production of _____ via the breakdown of ______.
Homeostasis level of blood glucose is ______/_____


A high level of blood glucose triggers insulin release from the pancreas. Insulin promotes the uptake of glucose and the synthesis of glycogen.
A low level of blood glucose triggers glucagon release from the pancreas. Glucagon promotes the production of glucose via the breakdown of glycogen.
Homeostasis level of blood glucose is 90mg/100mL
14In pancreas, _____ cells make glucagon when there is (low/high) blood sugar
Answer 3
In pancreas, Alpha cells make glucagon (low blood sugar)
14and _____ cells make insulin (when there is (low/high) blood sugar. _______ goes to the liver to make more glucose
And Beta cells make insulin (high blood sugar). Glucagon goes to the liver to make more glucose
14Glucagon goes to the _____ to make more glucose
Glucagon goes to the liver to make more glucose
15A high level of blood calcium triggers _____(hormone) release from the ______(gland). This hormone function is to ________
A high level of blood calcium triggers calcitonin release from the thyroid. Calcitonin promotes the excretion of calcium and its deposition into bone
15A low level of blood calcium triggers ______release from the ______. This hormone promotes ________
A low level of blood calcium triggers PTH release from the parathyroid. PTH promotes the retention of calcium by the kidney and the release of calcium from bone.
16 Hypothalumus neurohormoneseThese hormones are stored in and released from the_______ AKA _____, directly into the general circulatory system
The ______ pituitary makes enodocrine hormones
These hormones are stored in and released from the posterior pituitary, or neurohypophysis, directly into the general circulatory system
The anterior pituitary makes enodocrine hormones
17
Anterior Pituitary (AKA _____)
Anterior Pituitary (Adenohypohysis)
What hormones have tropic effects only, non tropic effects only, and both?
Answer 10
Tropic hormones
The hypothalamic hormones are secreted into the blood and travel through a short circulatory vessel (the portal vessel) directly to the ________ AKA ______ what is the function of tropic hormones ?
T or F pituitary hormones are never tropic hormones
The hypothalamic hormones are secreted into the blood and travel through a short circulatory vessel (the portal vessel) directly to the anterior pituitary or adenohypophysis.Here the tropic hormones regulate the release of other hormones from the pituitary into the general circulation. Some pituitary hormones are also tropic hormones
