Adrenaline plays the role of a very important neurotransmitter. In addition, adrenaline when released into the circulatory system, has effects on all the major organs in our body.
This happens when we encounter any stressful situation and to allow the body to be able to deal with the circumstances, the sympathetic nervous system releases adrenaline to deal with the stress. Adrenaline is associated with the flight or fight state that we need to get into to escape from many situations. This has evolved over evolution, as when faced with predators, the survivors were those who were able to either fight them or run and seek refuge. To accomplish this, the heart rate increases, the lungs beat faster to provide more oxygen to muscles and more energy is released from the energy stores we have in our body.
Adrenaline (also called epinephrine) is a hormone secreted by the adrenal glands ind released in the blood stream. It is also called epinephrine. Adrenaline helps the body adjust to sudden stress. by increasing the pulse and speeding up the conversion of food to energy in the muscles. It increases the strength and rate of the heartbeat and raises the blood pressure. It also speeds up the conversion of glycogen into glucose, which provides energy to the muscles.
In 1898, an American pharmacologist, John J. Abel, isolated the hormone adrenaline. Adrenaline can be extracted from the adrenal glands of animals or it can be chemically synthesized.
