The spinothalamic tract is a nerve tract in the anterolateral system in the spinal cord. [1] This tract is an ascending sensory pathway to the thalamus . From the ventral posterolateral nucleus in the thalamus, sensory information is relayed upward to the somatosensory cortex of the postcentral gyrus .
The spinohypothalamic tract or spinohypothalamic fibers is a sensory fiber tract projecting from the spinal cord to the hypothalamus directly to mediate reflex autonomic and endocrine responses to painful stimuli (the hypothalamus receives additional indirect nociceptive projections from the reticular formation (see: spinoreticular tract), and periaqueductal gray (see: spinomesencephalic tract).
Ventral posterolateral nucleus, which receives sensory information from the body via the medial lemniscus, and spinothalamic tracts. Ventral posteromedial nucleus , which receives sensory information from the head and face via the trigeminal nerve .
Sectional organization of spinal cord. The spinal cord is the main pathway for information connecting the brain and peripheral nervous system. [3] [4] Much shorter than its protecting spinal column, the human spinal cord originates in the brainstem, passes through the foramen magnum, and continues through to the conus medullaris near the second lumbar vertebra before terminating in a fibrous ...
The anterolateral system (ALS) is a bundle of afferent somatosensory fibers from different ascending tracts in the spinal cord. These fibers include those of the spinomesencephalic tract, spinothalamic tract, and spinoreticular tract amongst others. [5] Spinomesencephalic fibres project to the periaqueductal gray, and to the tectum.
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.
This tract was historically considered a cephalic division of the medial lemniscus due to the close proximity of the two ascending tracts. [2] Like the medial lemniscus in the dorsal column-medial lemniscus pathway (DCML), that carries mechanosensory information from part of the head and the rest of the body, the trigeminal lemniscus carries ...
The ventral posterolateral nucleus (VPL) is one of the subdivisions of the ventral posterior nucleus in the ventral nuclear group of the thalamus. [1] It relays sensory information from the second-order neurons of the neospinothalamic tract and medial lemniscus (of the dorsal column-medial lemniscus pathway) which synapse with the third-order neurons in the nucleus.
