Document Summary
Review questions: define sensory perception and differentiate between general and special senses, listing examples of each. Provide a specific example of where each is utilized. [1 mark: local anesthetics suppress action potentials in areas of the body that are near a sensory receptor or nerve. [2 marks: the sensory axons of tactile receptors synapse with neurons of the posterior horn of the spinal cord. In turn, these neurons synapse with neurons of the spinothalamic tract. When tactile receptors send action potentials to the spinal cord, these signals inhibit action potentials related to pain. [2 marks: when pain is perceived to occur in an area where the pain does not originate, it is called referred pain. The sensory receptors of superficial areas in our body synapse with neurons in the spinal cord that are also connected to the deep, visceral areas in our body. Describe the pathway from odorant molecule binding to a receptor to the olfactory bulb.
