epinephrine

Explanation:

Epinephrine is also called as adrenaline. It is both a neurotransmitter and a hormone. The adrenal glands produce the hormone epinephrine that can also be used as a drug for various important functions.

       If Samir were injected with epinephrine, he would experience rapid rush of adrenaline in his body and quick blood and oxygen flow throughout his body which will cause a feeling of arousal.

Samir was injected with epinephrine then he would experience feelings of arousal.

• To treat cardiac arrest.

• To treat asthma.

Epinephrine is synthesized from tyrosine in our body through the following steps:

• Tyrosine is converted into dopamine.

• Dopamine is converted into nor-epinephrine.

• Then nor–epinephrine converted into epinephrine.

Effects of epinephrine are;

• Activates the reticular formation of the brain.

• To increase the heart rates.

• To relaxe the blood vessels and decrease the blood flow resistance.
