What are the two major somatosensory pathways?
Last Updated: 21st April, 2020
- The main somatosensory pathways that communicate with the cerebellum are the ventral (or anterior) and dorsal (or posterior ) spinocerebellar tracts.
- The ventral spinocerebellar tract will cross to the opposite side of the body then cross again to end in the cerebellum (referred to as a double cross).

Also, what is the somatosensory pathway?
The somatosensory tracts (also referred to as the somatosensory system or somatosensory pathways) process information about somatic sensations such as pain, temperature, touch, position, and vibration. This information is received through receptors inside or at the surface of the body.
Also, what are the three sensory pathways? Anatomically, the ascending sensory systems consist of three distinct pathways: the anterolateral system (ALS), the dorsal column–medial lemniscal (DCML) pathway, and the somatosensory pathways to the cerebellum.
Thereof, what is the function of the somatosensory system?
The somatosensory system is the part of the sensory system concerned with the conscious perception of touch, pressure, pain, temperature, position, movement, and vibration, which arise from the muscles, joints, skin, and fascia.
What is special about the location of the primary somatosensory cortex?
The primary somatosensory cortex is responsible for processing somatic sensations. These sensations arise from receptors positioned throughout the body that are responsible for detecting touch, proprioception (i.e. the position of the body in space), nociception (i.e. pain), and temperature.
