  2. What organ does Adrenaline target? • Heart- via one receptor-increases heart rate, and force of contraction. • Blood vessels- via two receptors- causes constriction mainly in vessels of skin, kidneys, and liver. • Bronchial smooth muscles- via two receptors- causes broncho dilation. • Blood pressure- overall rise in blood pressure • Eye-via one receptor- increases size of pupil

  3. Where is adrenaline produced in the body? • Adrenaline is a hormone produced by the adrenal glands during high stress or exciting situations.

  4. The Adrenal Glands • Directly above the kidneys • Three inches in length, roughly • Many hormones produced by this gland • Norephine • Dopamine • Catecholamine

  5. Can a person release adrenaline on their own? How is the secretion of adrenaline related/controlled? No, adrenaline is released in response to the autonomic system. “Autonomic” is an automatic process regulated by the body. Adrenaline is released in response to various stimuli: exercise, stress, fear, decreased blood pressure, etc.

  6. What is the normal function of Adrenaline? • Adrenaline is mainly perceived to a threat in the environment. • The effect of adrenaline is increased heart rate and respiration ,increased oxygen and nutrient supplies to muscles and temporarily shutting down the maintenance of the body’s other systems.

  7. How does the adrenaline contribute to homeostasis ? • Adrenaline is the key determinant of responses to metabolic or global challenges to homeostasis and of manifestations of the emotional distress

  8. What diseases result from this condition ? • Cushings syndrome • Addisons disease which is hypoglycemia, dehydration, and rapid weight loss

  9. What are the causes and symptoms of hyper secretion of adrenaline…? • Tumors in the adrenal glands • Excessive amounts of cortocopitren • High blood pressure • High levels of glucose in blood • A change in the way the fat is sorted and distributed around the body

  10. What are treatments for over or under activation of the adrenaline pathway? • Supplements injections that are able to go against the activation of adrenaline

  11. How is adrenaline used clinically or commercially? • Adrenaline helps when you are injured or in pain • Adrenaline rush causes the muscles to perform respiration at an increased rate improving strength
