NEUROTRANSMITERS

• GAMMA AMINOBUTYRIC ACID (GABA) - Contributes to vision, and motor control, and plays a role in the regulation of anxiety.
• Benzodiazepines, which are used to help treat anxiety, function by increasing the efficiency of GABA
• GLUTAMATE - It plays a role in cognitive functions such as memory and learning.
• Excessive amounts of glutamate can cause excitotoxicity resulting in cellular death.
•  OXYTOCIN - Also called love hormone, it is both hormone and neurotransmitter. Produced by the hypothalamus and plays a role in social recognition, boding, and sexual reproduction.
• 1. Oxytocin causes the uterus to contract during labor. 
• ENDORPHINS- inhibit the transmission of pain signals and promote feelings of euphoria.
• ENDORPHINS - These chemical messengers are produced naturally by the body’s response to pain. 
• 1. EPINEPHRINE - considered both a hormone and neurotransmitter, it is also called the stress hormone
• NOREPINEPHRINE - A neurotransmitter that plays an important role in alertness is involved in the body’s fight or flight response.
• 1. HISTAMINE -  It plays a role in allergic reactions and is produced as part of the immune system’s response to pathogens.
• DOPAMINE -  Plays an important role in body movement, reward, motivation, and addictions.
• SEROTONIN - Plays an important role in regulating and modulating mood, sleep, anxiety, and appetite.
• SSRIs - are type of antidepressant medication commonly prescribed to treat depression, anxiety, panic disorder, and panic attacks.
• Selective serotonin reuptake inhibitors - usually referred to as SSRIs
• 1. ADENOSINE - Acts as a neuromodulator in the brain and is involved in suppressing arousing and improving sleep. 
• 1. NITRIC OXIDE - Plays a role in affecting smooth muscles, relaxing them to allow blood vessels to dilate and increase blood flow to certain areas of the body. 
• 1. CARBON MONOXIDE -  Usually known as being colorless, It acts as a neurotransmitter that helps modulate the body’s inflammatory response. 
• EXCITATORY NEUROTRANSMITTERS - they increase the likelihood that the neuron will fire an action potential.
• INHIBITORY NEUROTRANSMITTERS - They decrease the likelihood that the neuron will fire an action potential.
• Excitatory neurotransmitters include norepinephrine and epinephrine.
•  Inhibitory neurotransmitters include serotonin and GABA. 
• ACETYLCHOLINE - the only neurotransmitter in its class. It can be found in both the central and peripheral nervous systems. It plays a role in muscle movements as well as memory and learning. 
• GLUTAMATE - Associated with some diseases including Alzheimer’s disease, stroke, and epileptic seizures.
