Different Neurotransmitters

What are the neurotransmitters examples?

Neurotransmitters are electrical signals

[blank_start]Acetylcholine[blank_end]: - Found in the CNS and PNS - Enable muscle action, learning/memory, & REM sleep - Involved in neuroplasticity - Increased by learning - Decrease leads to Alzheimers [blank_start]Epinephrine[blank_end]: - Known as adrenaline - both a hormone and neurotransmitter - Secreted by adrenal glands - Released in response to situations providing fear, anxiety & physiological arousal - Increases heart rate, high blood pressure and fast breathing. - Also released in the brain. [blank_start]Norepinephrine[blank_end]: - Both a hormone and neurotransmitter - Mobilises the brain & body to act in stress - Increases alertness and arousal - Increases heart rate, glucose into blood, and blood to muscles. - Involved in regulating our mood and ability to concentrate

[blank_start]Serotonin[blank_end]: - Affects our well-being and happiness. Helps regulate mood and social behaviour, appetite and digestion, sleep, memory, and sexual functioning. Also involved in constriction of smooth muscles and the sleep-wake cycle. - Decreased levels leads to depression. - Sunlight, exercise, and increasing positive mood increases levels of this. - Inhibits aggression and antisocial behaviour.
