AP PSYCHOLOGY

Detailed explanation-1: -Neurotransmitters are often referred to as the body’s chemical messengers. They are the molecules used by the nervous system to transmit messages between neurons, or from neurons to muscles. Communication between two neurons happens in the synaptic cleft (the small gap between the synapses of neurons).

Detailed explanation-2: -Neurotransmitter – A chemical released from a neuron following an action potential. The neurotransmitter travels across the synapse to excite or inhibit the target neuron. Different types of neurons use different neurotransmitters and therefore have different effects on their targets.

Detailed explanation-3: -Calcium ion influx triggers synaptic vesicles to release neurotransmitter. 4. Neurotransmitter binds to receptors on target cell (in this case, causing positive ions to flow in).

Detailed explanation-4: -A neurotransmitter is a chemical that relays signals across the synapses between neurons. Neurotransmitters travel across the synaptic space between the terminal button of one neuron and the dendrites of other neurons, where they bind to the dendrites in the neighbouring neurons.
