Anatomy & Physiology Question #45
What is the role of epinephrine?
- Release of lipids by adipose tissues
- Control insulin production
- Glycogen breakdown
- Increased cardiac activity
The correct answers are A, C, D. Epinephrine, also called adrenaline, is a hormone that is secreted mainly by the medulla of the adrenal glands. It causes an increased cardiac output and to raise glucose levels in the blood. The extra amounts of glucose and fatty acids can be used by the body as fuel in times of stress or danger, when increased alertness and exertion are required. Epinephrine does not control insulin production.
