Question

Quizplus · Accepted Answer

The somatosensory projections ascend through the dorsal column system, which is responsible for the transmission of touch, vibration, and proprioceptive information to the brain. The spinothalamic system is responsible for the transmission of pain and temperature sensation, while the anterolateral system is responsible for both pain and temperature as well as crude touch and pressure. The primary cortical system refers to the primary somatosensory cortex, where the information ultimately gets processed and interpreted.
