Why does Central Cord Syndrome (CCS) typically result in greater motor weakness in the upper limbs compared to the lower limbs?
Why does Central Cord Syndrome (CCS) typically result in greater motor weakness in the upper limbs compared to the lower limbs?
- The spinothalamic tract, responsible for motor control, is more affected in the cervical region.
- CCS primarily damages the dorsal columns, which control motor function in the lower extremities.
- The corticospinal tract fibers controlling the arms are located more medially within the spinal cord. (correct)
- The corticospinal tract fibers controlling the legs are located more medially within the spinal cord.
