Corticospinal Tract - Physiopedia
网页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 [1]
Corticospinal tract - Wikipedia
网页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] There are more than one million neurons in the corticospinal tract, and they become myelinated usually in the first two years of life.

网页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]
Corticonuclear and corticospinal tracts - Kenhub
网页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.

网页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.
The corticospinal tract: Evolution, development, and human …
网页2016年10月5日 · The corticospinal tract (CST) plays a major role in cortical control of spinal cord activity. In particular, it is the principal motor pathway for voluntary movements. Here, we discuss: (i) the anatomic evolution and development of the CST across mammalian species, focusing on its role in motor functions; (ii) the molecular mechanisms ...

网页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 …
