The neurons of the enteric nervous system, one of three major systems in the human body, are responsible for sensing changes in your environment, sending information to your brain, and then sending out instructions to your muscles in response. Each neuron is connected to other neurons in a complex network that allows for communication between different parts of your body.
The enteric nervous system (ENS) is a large division of the peripheral nervous system (PNS) that can control gastrointestinal behaviour independently of central nervous system (CNS) input. Mammalian neurons are located in either the CNS (brain and spinal cord) or PNS (cells with soma outside the brain and spinal cord).
Enteric Nervous System
The enteric nervous system or intrinsic nervous system is one of the main divisions of the autonomic nervous system and consists of a mesh-like system of neurons that governs the function of the gastrointestinal tract.
When that system detects changes in your environment. Some of those changes get sent to your brain as messages. The “tone of your voice,” for example, and it can input the correct response into your muscles. But other changes, like temperature, pressure and light, need more specific inputs from the nervous system. To change, producing a sensation that might be a laugh or a grimace. When the emotional tone of your voice changes. The neurons behind your vocal cords spasm, sending messengers bouncing back and forth between your vocal cords. (Read the Related Stories below for more on the physiology of vocal cords and their signals.)
But when temperature and light change, something very strange happens: There’s no change in the electrical activity of your brain that’s connected to your vocal cords, so no units fire, no messages get passed and no muscle actions are produced.

Researchers explain that this reaction is actually quite common. Not just in people who are experiencing emotional problems. But also in athletes, who experience emotional changes like sadness and anger to how they train. It’s possible that the same mechanisms that affect how your brain thinks can also affect how your vocal cords work.
How Vocal Cord signals accurately and conveniently boost the performance of your Body
Humans have four primary voice boxes: the vocal cords themselves (or vocal cords bones), the vocal cords themselves, the vocal cords connecting the vocal cords to the head, and the vocal cords connected to the trunk. All of these vocal cords work differently, have unique functions and are affected in different ways by emotional changes.
Your vocal cords’ bones are the thickest part of your upper body and the biggest muscle group in your body. They connect directly to your brain, though primarily through your larynx (the upper lip).
The vocal cords themselves are bony structures made of cartilage and connect to each other by flexible tendons. Along the length of each cartilage-covered nerve.
When they start to feel sore or a little numb. Your body responds by sending an electrolyte fluid through your nerves that helps relax the nerves. That make up (and attach to) your vocal cords and says “there’s something broken”. So it can give them more stability and strength.
The vocal cords that make up your upper body also send signals back to the brain. That tell it to contract or relax. Some research has shown that emotional changes. Like how you feel emotionally about things. Can have a major impact on changes in how your body reacts to pain.
The way the nerve moves across the body and through the different muscles. Is controlled by the action potential, which sends out a chemical message that tells your muscle to contract.
Many different chemical messages travel across the nerve. Each message involves a neurotransmitter, which plays a critical role by binding to a specific receptor. Meanwhile, calcium activates two other receptors in a perfect timing coincidence. When this chain reaction happens, your muscles contract.
Understanding the movement of Nerve Cells
Understanding the movement of the nerve cells and the way the neurotransmitters code for the receptors. Is the key to developing training programs that mimic the electrical signals of muscle contractions. So they can be reliably trained.
First, we should look at how the enteric nervous system receives and processes messages that instruct the muscles to contract. One way the brain receives the information is by directly monitoring cerebrospinal fluid released from the brain. The nervous system then sends messages to the muscles through the synapses.
Another way the enteric nervous system gets information. Is through “transmitters” that travel across the synapse to take up the message and ultimately activate the receptor.
Muscle Building
In the case of muscle contractions, you want to make sure that the neurotransmitters in the message activate these receptors. To do that, your nutrition, hydration levels, and exercise levels (along with any evidence of injury) must be in equilibrium.
Those are the main three pieces of the puzzle to properly training your muscles.
Do not simply train your muscles in the gym. Breast-feeding, meditation sessions, walking, yoga, breathing exercises, and physical therapy are a great starting point if you don’t know where to start. However, take a step back and ask yourself, “Am I running my entire body through these different movement patterns as well?”
You can explain a little bit of the science of brain-to-muscle transmission, but the real test is to look at your entire body and make sure you are running your entire body with good technique. Your technique will dictate how effectively your body is applying this new training regimen.
We have already discussed that the central nervous system controls movement pattern use. If your brain tells your muscles to contract in the correct pattern, then the signals will be sent across the body in a timely manner.
The second point needs to be emphasized. Run as much as you can consistently throughout the week, not just in the gym. Don’t put one set of turns on your continuous training, do two sets of 39 inches for one exercise. Doctors recommend doing two to three times this amount of work per week.
The final point is application.
These three systems are your basic survival mechanisms.
The sympathetic (“fight-or-flight”) nervous system (also called your “fight or flight” system) is mostly responsible for getting your heart pumping blood to your muscles to fire on command. This system is triggered when you feel like you need to exert a certain amount of effort (called your “perceived exertion level”). This is classified as your thermic effect of food.
The parasympathetic (“rest and digest”) nervous system (also known as your “rest and digest” system) is essentially the opposite of the sympathetic nervous system. Parasympathetic stress, when supplied with the right stimulus, allows your muscles to relax and restore glucose and blood pressure levels to normal levels.
The enteric nervous system (ENS) is a large division of the peripheral nervous system (PNS) that can control gastrointestinal behaviour independently of central nervous system (CNS) input. Mammalian neurons are located in either the CNS (brain and spinal cord) or PNS (cells with soma outside the brain and spinal cord).
According to Beldini,
When you relax a muscle, the fibres of that muscle become more oxygenated, which results in a greater amount of oxygenated blood circulating in the body.

What’s more,
Under resting conditions, only the superficial layers of deep muscle layers are involved in muscle parasympathetic function. The deeper layers of muscle, when activated, secrete hormones as well.
Beldini
Should you workout to find your exercise environment?
Pairing up these three systems through exercise takes your body back to that state of thermogenesis, similar to a hibernation response for your muscles and tissues. Once you’re back in that rest-and-digest state, the effects of exercise are tremendous, strengthening every area of your body. The result? More calorie burning as your body recuperates and repairs.
Other than your imagination, there’s no surefire way to match your exercise selection for your energetic needs. If you’re exercising for weight loss but need more endurance, you may actually need more endurance than strength. The same goes for starting an endurance training regimen for your cardio system.
“If someone wants to lose fat, they should perform aerobic training and strength training to achieve this goal,” Beldini says. “When someone wants to increase muscle mass, they should perform a combination of aerobic training and strength training for the purpose of increasing muscle mass.”
Should you be a size 0 or need to lose a lot of body fat, you probably also need more strength training than cardio. “While strength training might slightly increase caloric expenditure, it is counterproductive for fat loss, as chronic overtraining will merely result in prolonged muscle loss,” Beldini says.
That being said, everyone responds differently to different training styles and intensities. If you’re new to strength training, whether you’re a beginner, competitive lifter or a seasoned athlete, start with lower reps with heavier weight and perform two to three sets of 8–12 repetitions per exercise, Beldini recommends.
