Hormones are chemical messengers made from originating in endocrine glands. They are composed of protein chains and cholesterol-based fats. They travel via the blood mostly to their target cells and organs. Here they bind to a receptor and start a reaction. This happens in seconds.
For example, your pancreas gland produces and secretes the hormone insulin. By way of the blood stream, insulin travels to other cells, latches onto their receptors and delivers glucose to them and thus produces your energy.
Neurotransmitters are also microscopic-sized chemical messengers produced by cells in the nervous system. They are made of tiny amine molecules and amino acids which are your neuropeptides.
They are released at end of your nerves to assist in nerve impulse conduction over the synaptic cleft, a normal space between your nerves. T
This occurs between nerves and between nerve and muscles. It takes nano –seconds for this to happen which allows your nerves to respond almost instantly in one of two important ways: action or inhibition of action.
There are two primary roles that the neurotransmitters have in your body. One is an inhibitory role that stops or slows tissue functions, such as helping you to relax. Another is an excitatory role that speeds-up tissue function.
Let’s look at a well-known neurotransmitter, Adrenaline (aka epinephrine or EPI). Nerve endings in the Autonomic part of the CNS (central nervous system) release this Adrenaline into a specific, sympathetic neuron synaptic space. This results immediately in an exciting fight or flight response which may save your life.
Plus, some of these neurons are inside your adrenal gland, (adrenal medulla). This gland houses both EPI and Nor-EPI plus a multitude of tiny blood vessels. As the vessels eagerly sop up the EPI and NorEPI, the neurotransmitters become known as hormones.
Their delivery via the blood vessels to other organ tissues, encourages a cascade of events. For instance, they are delivered your kidneys. The kidneys release other hormones that cause blood vessel constriction which would be life saving if you are deeply cut.
You can easily tell that the Great Communicators are the Neurotransmitters and the Hormones. These can be evaluated when there is indication that this would assist you in growing a healing, healthy life.
