I read that the only 2 neurotrasmitters in the PNS are acetylcholine and norepinephrine. Acetylcholine being the main one. That can't be right can it? What about epinephrine?

Neurotransmitters in the PNS (peripheral nervous system) are chemical messengers that transmit signals between neurons and other cells in the body. They are responsible for controlling various bodily functions, such as movement, sensory perception, and organ function.
Neurotransmitters work by binding to specific receptors on the surface of target cells, triggering a series of chemical reactions that ultimately result in the transmission of a signal. This signal can either excite or inhibit the activity of the target cell, depending on the type of neurotransmitter and receptor involved.
The main neurotransmitters in the PNS include acetylcholine, norepinephrine, dopamine, serotonin, and gamma-aminobutyric acid (GABA). Each of these neurotransmitters has different functions and can affect different parts of the body.
An imbalance of neurotransmitters in the PNS can lead to various neurological and psychiatric disorders. For example, low levels of dopamine have been linked to Parkinson's disease, while high levels of serotonin have been associated with anxiety and depression.
Yes, neurotransmitters in the PNS can be affected by external factors such as drugs, alcohol, and stress. These substances can alter the levels or activity of neurotransmitters, leading to changes in mood, behavior, and bodily functions.
