Norepinephrine.
The main function of neurotransmitters is to transmit signals from one part of the body to another part of the body. Usually, these signals are passed between neurons.
The sympathetic nervous system can be classified as adrenergic, based on the main neurotransmitters used.

The neurotransmitters classified as catecholamines are dopamine, norepinephrine, and epinephrine. These neurotransmitters are derived from the amino acid tyrosine. Catecholamines play important roles in regulating mood, stress response, and physiological functions in the body.
The main stress is on the second syllable (the "tog" part). This is distinct from "photograph", where the first syllable is the stressed one.

Neuropeptides that affect a neuron's response to other neurotransmitters are called neuromodulators. They can enhance or inhibit the effects of neurotransmitters, thereby influencing neuronal excitability and synaptic transmission. By modulating the activity of neurotransmitters, neuromodulators play a crucial role in regulating various physiological processes, including pain perception, mood, and stress responses.
Neurotransmitters to the synapse and the neurotransmitters bind with the receptors releasing the second messengers.

One medical intervention to help cope with stress is antidepressants. Antidepressants correct chemical imbalances of neurotransmitters in the brain which cause changes in mood and behavior. This helps reduce stress on the body. Another intervention that can help reduce stress is acupuncture. Acupuncture blocks the production of a hormone, hypothalamus pituitary adrenal (HPA) that is known to cause stress in the body.
Successful: the second. Comfortable: the first.
The three main types of stress in a rock are shearing, tension, and compression.
