Detailed explanation-1: -Neurotransmitters are chemical messengers that your body can’t function without. Their job is to carry chemical signals (“messages”) from one neuron (nerve cell) to the next target cell. The next target cell can be another nerve cell, a muscle cell or a gland.
Detailed explanation-2: -Answer and Explanation: The different types of chemical messengers are hormones, neurotransmitters, neuropeptides, and pheromones.
Detailed explanation-3: -Four neurotransmitters come under the chemical classification of biogenic amines. These are epinephrine, norepinephrine, dopamine, and serotonin. Although epinephrine is the transmitter in frogs, in mammals its role has been supplanted by norepinephrine.
Detailed explanation-4: -The endocrine system consists of a series of glands that produce chemical substances known as hormones ([link]). Like neurotransmitters, hormones are chemical messengers that must bind to a receptor in order to send their signal.
Detailed explanation-5: -Glutamate. This amino acid is common in your diet. GABA (-aminobutyric acid) If glutamate is the most excitatory chemical messenger, then GABA is its polar opposite. Dopamine. Adrenaline (Epinephrine) Serotonin. Oxytocin. Acetylcholine. 03-Apr-2020
