Corticospinal tract - Wikipedia
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. [1]
Corticospinal Tract - Physiopedia
The Corticospinal tract (CST), also known as the pyramidal tract, is a collection of axons that carry movement-related information from the cerebral cortex to the spinal cord. It forms part of the descending spinal tract system that originate from the cortex or brainstem
Pyramidal tracts: Corticospinal and corticonuclear tracts - Kenhub
2023年7月27日 · The pyramidal tract provides voluntary control of muscular movements. It consists of two distinct pathways, the corticonuclear tract and the corticospinal tract. The corticospinal tract carries motor signals from the primary motor cortex in the brain, down the spinal cord, to the muscles of the trunk and limbs.
Neuroanatomy, Corticospinal Cord Tract - StatPearls - NCBI Bookshelf
2023年8月14日 · The corticospinal tract, AKA, the pyramidal tract, is the major neuronal pathway providing voluntary motor function. This tract connects the cortex to the spinal cord to enable movement of the distal extremities.[1]
The Descending Tracts - Pyramidal - TeachMeAnatomy
2022年12月16日 · Pyramidal tracts – These tracts originate in the cerebral cortex, carrying motor fibres to the spinal cord and brain stem. They are responsible for the voluntary control of the musculature of the body and face.
Neuroanatomy, Lateral Corticospinal Tract - StatPearls - NCBI Bookshelf
2023年7月24日 · The corticospinal tract is the largest descending tract present in humans and is divided into anterior and lateral components. The lateral corticospinal tract sends fibers predominantly to the extremity muscles, and the cortical innervation is contralateral, in other words, the left motor cortex controls the right extremities.

2024年8月19日 · The corticospinal tract (also known as the pyramidal tract) is a descending white matter tract primarily concerned with motor function that extends caudally from the motor cortex to synapse with motor neurons of the spinal cord in the anterior horns.. Gross anatomy Central connections. Corticospinal fibers are axons from upper motor neurons in the cerebral …
Corticospinal Tract Lesion - StatPearls - NCBI Bookshelf
2023年8月14日 · The corticospinal tract controls primary motor activity for the somatic motor system from the neck to the feet. It is the major spinal pathway involved in voluntary movements. The tract begins in the primary motor cortex, where the soma of pyramidal neurons are located within cortical layer V. Axons for these neurons travel in bundles through ...
Corticospinal populations broadcast complex motor signals to ...
2021年11月4日 · Many models of motor control emphasize the role of sensorimotor cortex in movement, principally through the projections that corticospinal neurons (CSNs) make to the spinal cord.
