Concept #1: Somatic Sensory Receptors

Concept #2: Intro to Somatic Sensory Pathways and Spinothalamic Tract

Concept #3: The Dorsal Columns

Concept #4: Sensory Fiber Types

Practice: Opiates (e.g. morphine) are drugs that reduce pain sensation, but leave pressure and temperature sensation intact. Which of the following types of sensory receptors are affected by opiates?

Practice: King Joffrey gets punched in the neck, because he deserves it. As a result, he can no longer feel pain or temperature in his right hand. Which of the following somatosensory tracts was damaged by the punch?

Practice: My Khaleesi gets punched in the neck—though she absolutely does not deserve it, Westeros is a cruel place. As a result, she can no longer feel pressure or vibrations in her right hand. Which of the following somatosensory tracts was damaged by the punch?

Practice: Lidocaine is a local anesthetic—it prevents transmission of pain signals from a local area. Lidocaine works well for preventing the transmission of dull/achy pain, but often still allows sharp/stabbing pain, pressure and temperature to get through. Regions treated with lidocaine do not become paralyzed—motor function is retained. Which of the following fiber types are affected by lidocaine?
