2nd-order neurons : carry the signal up the spinal cord to the brain stem 3rd-order neurons : carry the signal to the sensory region of the cerebral cortex Descending tracts: Carry motor and visceral impulses down the cord Pathway consists of 2 types of neurons : Upper motor neurons (...
3.1 Spinal cord injury (SCI) SCIs are considered catastrophic, serious neurological disorder in veterinary medicine that disturbed motor, sensory, and autonomic functions so remained one of the main causes of morbidity and mortality. It resulted from trauma, disease, or degenerative damage in the sp...
Spinal cord injuryis a serious clinical condition, resulting in the interruption of nerve communication of the ascending sensory pathways and descending motor pathways between the brain and the periphery of the body. The spinal cord, which constitutes a portion of thecentral nervous system, enables ...
Structure of the spinal cord seen from a dorsal view. Spinal cord: Cross-section Descending tracts are the pathways by which motor signals are sent from the brain to the spinal cord. They are also called motor tracts, due to their involvement in movement coordination. These tracts can be ...
The first candidate for such an intermediate pathway to relay the CST and/or RST connectivity is the dPST, which is distributed uniformly over a wide area throughout the spinal cord22,23, and serves as an intermediate relay for descending motor commands to activate the lumbar circuit15,16,24...

Spinal cord neural pathways are found within the spinal cord white matter. On each side, the white matter is divided into three funiculi: anterior, lateral, and posterior. Ascending tracts convey information from the periphery to the brain. On the other hand, the descending tracts carry informati...
The spinal cord is part of the central nervous system and coordinates motor, sensory, and reflex signals. Anatomically, the spinal cord is located within the spinal canal and extends from the botto...
Descending Tracts: The descending tracts in the spinal cord originate from cortical areas in the brain stem. The descending pathway carries information associated with maintaining motor activities such as posture, muscle tone, balance, and somatic and visceral activity. These specific tracts carry inform...
