GENERAL HISTOLOGY

Detailed explanation-1: -Spinothalmaic tract. The spinal cord, basically a highway for nerves, streamlines sensory and motor signals to the brain and the body. Information detected by sensory receptors in the periphery is transmitted along ascending neural tracts in the spinal cord.

Detailed explanation-2: -The ascending tracts include the dorsal column-medial lemniscus system, the spinothalamic system, and the spinocerebellar system. These tracts carry sensory information from the periphery, such as pain, touch, and temperature to the brain.

Detailed explanation-3: -The spinothalamic tract is a collection of neurons that carries information to the brain about pain, temperature, itch, and general or light touch sensations. The pathway starts with sensory neurons that synapse in the dorsal horn of the spinal cord.

Detailed explanation-4: -The lateral corticospinal tract (LCST) is the largest descending motor pathway. It begins in the cerebral cortex, receiving a range of inputs from the primary motor cortex, premotor cortex and supplementary motor areas.

Detailed explanation-5: -The white matter of the spinal cord contains a mixture of ascending (sensory or afferent) and descending (motor or efferent) tracts.
