Neurotransmitters are powerful chemicals that regulate numerous physical and emotional processes such as mental performance, emotional states and pain response. Virtually all functions in life are controlled by neurotransmitters. They are the brain's chemical messengers.Interactions between neurotransmitters, hormones, and the brain chemicals have a profound influence on overall health and well-being. When our concentration and focus is good, we feel more directed, motivated, and vibrant. Unfortunately, if neurotransmitter levels are inadequate these energizing and motivating signals are absent and we feel more stressed, sluggish, and out-of-control.

Effects:

Control the appetite center of the brain

Stimulates Corticotropin Releasing Factor, Adrenalcorticotropic Hormone, & Cortisol

Regulate male and female sex hormone

Regulates sleep

Modulate mood and thought processes

Controls ability to focus, concentrate, and remember things

The Mind Body Connection

The chemistry of our bodies can alter, and be altered by our every thought and feeling. Our bodies and our minds are truly interconnected, the health of one depends on the health of the other.

Neurotransmitter Imbalances:

Disrupted communication between the brain and the body can have serious effects to ones health both physically and mentally. Depression, anxiety and other mood disorders are thought to be directly related to imbalances with neurotransmitters. The four major neurotransmitters that regulate mood are Serotonin, Dopamine, GABA and Norepinephrine.

The Inhibitory System is the brains braking system, it prevents the signal from continuing. The inhibitory system slows things down. Serotonin and GABA are examples of inhibitory neurotransmitters.

GABA (Gamma amino butyric acid) GABA is the major inhibitory neurotransmitter in the central nervous system. It helps the neurons recover after transmission, reduces anxiety and stress.It regulates norepinephrine, adrenaline, dopamine, and serotonin, it is a significant mood modulator.

Serotonin imbalance is one of the most common contributors to mood problems. Some feel it is a virtual epidemic in the United States. Serotonin is key to our feelings of happiness and very important for our emotions because it helps defend against both anxiety and depression. You may have a shortage of serotonin if you have a sad depressed mood, anxiety, panic attacks, low energy, migraines, sleeping problems, obsession or compulsions, feel tense and irritable, crave sweets, and have a reduced interest in sex. Additionally, your hormones and Estrogen levels can affect serotonin levels and this may explain why some women have pre-menstrual and menopausal mood problems. Moreover, daily stress can greatly reduce your serotonin supplies.

The Excitatory Neurotransmitter System can be related to your car's accelerator. It allows the signal to go. When the excitatory neurotransmitter system is in drive your system gets all reved up for action. Without a functioning inhibitory system to put on the brakes, things (like your mood) can get out of control

Epinephrine also known as adrenaline is a neurotransmitter and hormone essential to metabolism. It regulates attention, mental focus, arousal, and cognition. It also inhibits insulin excretion and raises the amounts of fatty acids in the blood. Epinephrine is made from norepinephrine and is released from the adrenal glands. Low levels have been can result in fatigue, lack of focus, and difficulty losing weight. High levels have been linked to sleep problems, anxiety and ADHD.

Dopamine is responsible for motivation, interest, and drive. It is associated with positive stress states such as being in love, exercising, listening to music, and sex . When we don't have enough of it we don't feel alive, we have difficulty initiating or completing tasks, poor concentration, no energy, and lack of motivation. Dopamine also is involved in muscle

Muscle Fatigue

Muscle contractions in our bodies are what allow us to move and produce heat, but what exactly is a muscle contraction? Well, a muscle contraction is a process in which tension develops in the muscle tissue. In a skeletal muscle, sarcomeres are the units of contraction and are made up of thick, myosin filaments and thin, actin filaments.The sarcoplasmic reticulum, a network of tubes, runs parallel to the filaments. Sarcomeres are also found in the myofibrils, the contracting fibers of a myofiber…
