Adrenal Gland Medulla By: Abigail Moss & Sydney Lineberry
Where are they located? The adrenal glands are located at the top of each kidney. The adrenal medulla is located in the inner part of the adrenal gland.
What types of hormones does the gland produce? The adrenal medulla secretes: Epinephrine(adrenaline) Norepinephrine(noradrenaline)
The affect of the hormones on the body Epinephrine(adrenaline): this hormone aids the body when responding to stressful situations(fight or flight response), it will increase the heart rate and glucose within the body Norepinephrine(noradrenaline): this hormone also aids the body in stressful situations and increases blood pressure in response to severe stress
Why are the hormones important for homeostasis? These hormones are important for homeostasis because it helps a person cope with physical and emotional stress. When put into a stressful situation a person’s body can be taken from homeostasis and the hormones which the adrenal medulla secrete help to take the body back to a homeostatic state.
Feedback Mechanisms and Antagonistic Hormones Antagonistic Hormones:Hormones that act to return body conditions to acceptable limits from opposite extremes. The medulla is regulated by nerve impulses from the hypothalamus The adrenal cortex is regulated by negative feedback. -Negative feedback occurs when the rate of the process decreases as the concentration of the product increases.
What happens if the gland does not function properly? Addison's Disease: Adrenal cortex fails to produce enough cortisol and aldosterone. Adrenal Cancer: Tumors that cause adverse changes within the body because of the excess hormones they produce. Cushing Syndrome: Over production of the hormone cortisol Congenital Adrenal Hyperplasia: Low levels of cortisol
What can be done medically to correct problems of the gland not functioning properly? Surgery (this is the primary treatment) Medical Therapy
