|
Answer» Neurotransmitters are chemical messengers. The important neurotransmitters are: Acetylcholine: It is a chemical released by motor neurons of the nervous system to activate muscles. Dopamine: It is released by the brain. If the level of dopamine is normal, we experience happy, pleasant feelings. It also plays an important role in the motivational process. Norepinephrine: It increases the force of skeletal muscles, especially during fight or flight response. Serotonin: It plays a role mainly in cognition, reward, learning, and memory. It also controls wakefulness, sleep, hunger, thirst, and liking. Glutamate: It helps in learning, memory, and maintaining sugar levels. GABA (Gama Amino Butyric Acid): It is the chief inhibitory neurotransmitter i.e. its principal role is to reduce the excitability of neurons throughout the nervous system. If it is less, it leads to convulsions and we cannot control body movements. |
