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: -The nervous system uses tiny cells called neurons (NEW-ronz) to send messages back and forth from the brain, through the spinal cord, to the nerves throughout the body. Billions of neurons work together to create a communication network.
