Final answer:
Neurotransmitters are chemical messengers that transmit signals between neurons in the brain and the body. They regulate functions such as mood, appetite, sleep, and memory. Examples include serotonin, dopamine, and acetylcholine.
Step-by-step explanation:
Neurotransmitters are chemical messengers that transmit signals between neurons in the brain and the rest of the body. They play a crucial role in regulating various functions such as mood, appetite, sleep, and memory.
Some examples of neurotransmitters include serotonin, dopamine, and acetylcholine. Serotonin is involved in regulating mood and appetite, while dopamine is associated with reward and motivation. Acetylcholine is important for memory and muscle movement.
Neurotransmitters are found throughout the nervous system, including the brain, spinal cord, and peripheral nerves. They can be released by a presynaptic neuron and bind to specific receptors on a postsynaptic neuron, transmitting the signal from one neuron to another.
