Therefore, the 12 pairs of cranial nerves, which arisefrom the brain, and the 31 pairs of spinal nerves originating from the spinal cord with their associated ganglia are, by convention, part of the peripheral nervous system. Both the brain and spinal cord are organized into gray matter, ...
This entry describes the gross anatomy of the spinal cord, including its blood supply, and its internal structure. The various descending motor pathways (corticospinal, rubrospinal, tectospinal, vestibulospinal and reticulospinal) and the ascending somatosensory pathways (anterolateral system (ALS), ...
The spinal cord has a small diameter, it lies within a rigid bony canal and it contains important neural elements. Therefore, relatively small lesions within the parenchyma or in the extraaxial space often present with serious neurologic deficits. For these reasons, imaging of the spine and ...

Knowledge of spinal cord vascular anatomy is essential to the neurosurgeon planning and undertaking procedures on of the spinal cord. This article relates general concepts and nomenclature regarding this unique circulation and describes the regional and segmental arterial and venous anatomy of the spinal ...
Explore Innerbody's 3D anatomical model of the spinal cord, a major component of the central nervous system.
The spinal cord is the main bundle of nerve fibers connecting the brain to the rest of the body. The spinal cord ends near the L1 and L2 vertebrae, where it divides into bundles of nerve roots called the cauda equina. 脊髓是连接大脑与身体其他部分的主要神经纤维束。脊髓终止于腰1或腰2椎体...
The anatomy of spinal cord vessels is formed systematically by three constitutions, extrinsic and intrinsic spinal arteries and veins. The extrinsic arterial supply to the cord has a metameric organization and makes a functionally effici... MW Baik 被引量: 1发表: 2000年 ...
The spinal cord is a continuation of the brainstem. It extends from the foramen magnum at the base of the skull to the L1/L2 vertebra where it terminates as the conus medullaris (medullary cone). A thin thread called filum terminale extends from the tip of the conus medullaris all the wa...
