Detailed explanation-1: -Molecules in a certain medication attach to receptors on nerve cells. This prevents the normal chemical signal from binding to the receptor.
Detailed explanation-2: -Neurotransmitters are the chemical messengers that allow electrical signals from neurons to be transmitted to the postsynaptic neuron or effector target.
Detailed explanation-3: -Sensory receptors are nerve endings or specialised cells which convert (transduce) stimuli from the environment into afferent nerve impulses; the impulses pass into the CNS where they initiate appropriate voluntary or involuntary responses.
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.
