The lateral spinothalamic tract (or lateral spinothalamic fasciculus), is a bundle of afferent nerve fibers ascending through the white matter of the spinal cord, in the spinothalamic tract, carrying sensory information to the brain. It carries pain, and temperature sensory information (protopathic sensation) to the thalamus.
Two of the five sensory modalities, pain and temperature, cross sides at the anterior white commissure, reaching the contralateral side about two vertebral levels rostral to their origin. The spinothalamic tract thus decussates very soon after entering the spinal cord, ascending in the spinal cord, contralateral to the side from where it ...
The substantia gelatinosa is one point (the nucleus proprius being the other) where first order neurons of the spinothalamic tract synapse. Many μ and κ-opioid receptors, presynaptic and postsynaptic, are found on these nerve cells; they can be targeted to manage pain of distal origin. For instance, neuraxial administration of opioids results ...
The spinomesencephalic pathway, spinomesencephalic tract or spino-quadrigeminal system of Mott, includes a number of ascending tracts in the spinal cord, including the spinotectal tract. [ 1 ] [ 2 ] [ 3 ] The spinomesencephalic tract is one of the ascending tracts in the anterolateral system of the spinal cord that projects to various parts of ...
The dorsal column–medial lemniscus pathway (DCML) (also known as the posterior column-medial lemniscus pathway (PCML) is the major sensory pathway of the central nervous system that conveys sensations of fine touch, vibration, two-point discrimination, and proprioception (body position) from the skin and joints.
The pyramidal tracts include both the corticobulbar tract and the corticospinal tract.These are aggregations of efferent nerve fibers from the upper motor neurons that travel from the cerebral cortex and terminate either in the brainstem (corticobulbar) or spinal cord (corticospinal) and are involved in the control of motor functions of the body.
Despite the origin of its moniker, Wimpy Grills didn’t serve cans of spinach but the burgers preferred by J. Wellington Wimpy, who was known to do anything to get a burger. Since its founding in ...
The spinothalamic tract is a sensory pathway originating in the spinal cord. It transmits information to the thalamus about pain, temperature, itch and crude touch . There are two main parts: the lateral spinothalamic tract , which transmits pain and temperature, and the anterior (or ventral) spinothalamic tract , which transmits crude touch ...
