Transcript of Adrenal Gland Project

Works Cited The Adrenal Gland Adrenal Gland Pathway to production Other interesting facts about this gland Actions of the Hormone: Cortisol • Also known as hydrocortisone

• Helps with the metabolism of glucose, especially in times of stress and in response to low levels of blood glucocorticoids
• Its also actions include mobilization of fats, proteins, and carbohydrates
• Enhances activity of other hormones like glucagon
• Bursts of immunity Potential Problems from imbalances of these hormones By: Alex Wright

AP Bio 2013 • 2 structures located on top of Kidneys
The right is triangular shaped and the left is semilunar

• Stimulated by (ACTH) Adrenocorticotropic Hormone

• Also produces weak androgens

• Fight or flight

• 2 parts the outer adrenal cortex and the inner medulla which produce hormones Different Hormones produced by the Adrenal gland • Activated in fight or flight
• The Cortex produces cortisol and aldosterone
• The Medulla produces epinepherine But the main hormones produced in the cortex are ... Cortisol • Its primary functions are to increase blood sugar in “fight or flight” situations for more energy

• Aid in fat, protein, and carbohydrate metabolism

• Helps increase immunity • But in other terms its main job is to help the body to react to stress and
maintain blood pressure in cardiovascular functions Main uses of Cortisol • Bone mass decrease
• Obesity and type 2 diabetes are metabolic problems caused by too much cortisol
• High blood sugar (hyperglycemia) or pressure
One could go into cardiac arrest or
Also the possibility of peeing too much! Cushing's syndrome (hypercortisolism) Caused by: a tumor on the pituitary gland thus releasing more ACTH or from excess smoking and or stress
Abnormal obesity is excessive abdominal fat around the stomach and abdomen
Moon face Addison's disease (hypocortisolism/hypoaldosteronism) Caused by: damage to the adrenal cortex or blood loss Symptoms
Increasingly tanned skin
Abdominal pain
Weight loss Darkens skin pigment Can lead to Type 1 Diabetes and Thyroid disease The Stress Related Gland Tips to help prevent Cortisol or Epinephrine related health problems: Avoid over-eating Exercise regularly Relieve stress by meditating
People with higher levels of cortisol tend to eat more food because the amount of insulin released

If gone, the Kidneys would release more salt

Potential uses for cortisol: to help more emotional short term memories and to help people control their phobias

Diurnal variation: high levels in the morning and low
at night http://en.wikipedia.org/wiki/Cortisol



http://www.newworldencyclopedia.org/entry/Epinephrine Cortisol is the most active steroid in the Adrenal Gland Hypothalmus > Pituatary gland > ACTH in blood
stream > adrenal cortex or medula

Cortisol, epinephrine, and aldosterone created in the
different zonas > to the blood stream to reach the cells Produced in stressful situations All of this due to high stress levels!!! Negative effects of too much Cortisol And Charlie Hilger ... and Hogan Heritage Aldosterone Actions of the Hormone: Aldosterone Also referred to as adrenaline and noradrenaline
Epinephrine dilates the blood vessels in skeletal muscles in the liver.
Dopamine is also released
Occasionally called the emergency hormone (released while under stress)
Also causes airways to dilate It is a mineralcorticoid
Stimulates re-absortion of salt in the kidneys
Regulates electrolyte levels
It is mainly know for its regulation of the exchange of potassium and sodium
Helps the increase of blood pressure in flight or flight situations
Also helps with water retention by not allowing you to urinate as much so the cells are able to absorb more water The next hormone we will talk about is
epinephrine which is produced in
the medulla Epinephrine Actions of the Hormone: Epinephrine Production and secretion is mainly due in response to a threat
More glucose is secreted into the blood stream
Thus with the factors of more oxygen and glucose in the blood stream means more energy production
This all due to have more energy in a panicked situation such as seeing a velociraptor Effects of these
hormones Follow him on twitter: @charlesdawesome
