Sensory/Ascending Spinal Tracts
“Her hands were the softest thing that he ever touched, or at least what he imagined”, apparently his spinothalamic tract is functioning well! Today we will talk about sensory or ascending spinal tracts. We will start by general overview about spinal ascending and descending tracts, then we will focus on sensory tracts. We will also discuss different injuries of spinal cord, and what symptoms will happen as a result of that.
