Spinal motor tracts
WebThe 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. Located in the white matter of the spinal cord, the ascending sensory tracts arise from either the the cells of the spinal … WebCorticospinal tract. The corticospinal tract is a white matter motor pathway starting at the cerebral cortex that terminates on lower motor neurons and interneurons in the spinal cord, controlling movements of the limbs and trunk.

WebJan 17, 2024 · Spinal Cord Columns. The spinal cord white matter is subdivided into columns. The dorsal columns carry sensory information from mechanoreceptors (cells that respond to mechanical pressure or distortion). The axons of the lateral columns ( corticospinal tracts ) travel from the cerebral cortex to contact spinal motor neurons. WebTracts descending to the spinal cord are involved with voluntary motor function, muscle tone, reflexes and equilibrium, visceral innervation, and modulation of ascending sensory signals. The largest, the corticospinal tract, originates in broad regions of the cerebral cortex. Smaller descending tracts, which include the rubrospinal tract, the vestibulospinal …
