Where Is Anterolateral System?

The spinothalamic tract

(also known as anterolateral system or the ventrolateral system) is a sensory pathway from the skin to the thalamus. From the ventral posterolateral nucleus in the thalamus, sensory information is relayed upward to the somatosensory cortex of the postcentral gyrus.

What sensation is carried by anterolateral system?

The anterolateral system, a component of the somatosensory system, signals nociception, thermal sensations, and nondiscriminative touch originating in the body and in the face. Free nerve endings transduce nociceptive and innocuous stimuli over small-diameter, thinly myelinated, or unmyelinated somatic afferent fibers.

What is the anterolateral?

refers to a collection of ascending pathways that carry pain and temperature--as well as related touch--sensations from the spinal cord to the brainstem or thalamus. The anterolateral system is generally considered to contain the spinothalamic tract, spinoreticular tract, and spinomesencephalic tract.
