Dentists often use medicines called local anesthetics when removing a tooth so that the patient does not feel pain. Which of the following statements describes how local anesthetics block pain?
The anesthetic molecules attach to the lining of the mouth and constrict blood vessels there.
The anesthetic molecules bind to sensory neurons and prevent them from sending nerve impulses to the brain.
The anesthetic molecules bind to motor neurons and prevent them from sending nerve impulses to the mouth.
The anesthetic molecules enter the salivary glands and cause large amounts of saliva to be released in the mouth.
