Dopamine and Serotonin

Sweating in social situations can be due to anxiety or nervousness, which activates the body's fight or flight response. This response can cause an increase in body temperature, leading to sweating. Additionally, feeling self-conscious or overwhelmed in social settings can trigger the body to sweat as a way to regulate temperature while under stress.
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.
Endorphins are neurotransmitters that act as natural painkillers and play a role in reducing stress and increasing feelings of pleasure. They are produced in response to various stimuli, such as exercise, excitement, or pain, and help regulate mood and emotions.
Neurotransmitters that bind to the postsynaptic membrane generate a response by either depolarizing or hyperpolarizing the postsynaptic neuron. This response can lead to the generation of an action potential if the threshold is reached, propagating the signal further along the neuron.
Cortisol is the primary chemical that signals the brain about the body's response to stress. It is released by the adrenal glands in response to stress and helps regulate important bodily functions during stressful situations.
Hormones and neurotransmitters work together in the body to regulate physiological processes by communicating messages between cells. Hormones are chemical messengers released by glands into the bloodstream to target specific organs, while neurotransmitters are released by nerve cells to transmit signals between neurons. Both hormones and neurotransmitters bind to receptors on target cells, triggering a response that helps regulate processes such as growth, metabolism, and mood.
These are typically known as neuromodulators; they can either change the rate at which a neurotransmitter is released, or alter the response to a certain neurotransmitters.
Palms sweat as a response to stress or anxiety, triggered by the body's fight-or-flight response. This reaction helps regulate body temperature and improve grip in tense situations.

Neurotransmitters are released in response to stimulation. They alter the physiology of the postsynaptic cell. They are synthesized by a presynaptic neuron. They bind to specific receptors on the postsynaptic cell.
Planning for non-crisis situations and in response to hypothetical situations
Hormones, neurotransmitters, and enzymes are secreted by various glands in response to signals from the nervous system and chemical changes in the blood. These substances help regulate various physiological processes in the body.
The parasympathetic and sympathetic nervous systems work together to regulate the body's response to stress and relaxation. The sympathetic system activates the "fight or flight" response during stress, increasing heart rate and releasing adrenaline. The parasympathetic system then helps the body relax after the stress has passed, slowing heart rate and promoting digestion. Together, they maintain balance in the body's response to different situations.
