Exteroceptors are the afferent nerve endings that sense stimuli originating from outside of the body, such as pain, touch, vibration, temperature, and sound. One type of exteroceptors are known as mechanoreceptors, which are receptors that respond to external mechanical stimuli such as touch, pressure, and vibration.
There are two sets of nerves: the central nervous system and the peripheral (outside) nervous system. The central nervous system is made up of the brain and spinal cord. The peripheral (outside) nervous system is all the other nerves in the body. The nerves are very close together.Special chemicals called neurotransmitters carry messages from one nerve to the next nerve.Drugs affect the body by changing the neurotransmitters in the nerves.he peripheral (outside) nervous system is all the other nerves in the body.
