我们回顾了脊髓的解剖结构，提供了与关键功能和临床相关神经通路的相关性，以及磁共振成像。在外周，主下行（皮质脊髓束）和上行（股薄肌或楔束和脊髓丘脑束）通路组成白色物质。在中央，灰质可分为多个层。椎板1-5在后角中携带敏感神经元信息，椎板9在前角中携带大多数下运动神经元信息。单侧皮质脊髓束（上运动神经元信息）或楔薄肌束（触摸和振动）的损伤与同侧临床表现相关，而单侧脊髓丘脑束（疼痛-温度）的损伤与对侧临床表现相关。连合纤维的损伤与悬挂的双侧“腰带”感觉水平相关。当双侧脊髓受累时，自主神经功能障碍是预期的。(C)2016 Elsevier Inc. All rights reserved.
We review the anatomy of the spinal cord, providing correlation with key functional and clinically relevant neural pathways, as well as magnetic, resonance imaging. Peripherally, the main descending (corticospinal tract) and ascending (gracilis or cuneatus fasciculi and spinothalamic tracts) pathways compose the white matter. Centrally, the gray matter can be divided into multiple laminae. Laminae 1-5 carry sensitive neuron information in the posterior horn, and lamina 9 carries most lower motor neuron information in the anterior horn. Damage to the unilateral corticospinal tract (upper motor neuron information) or gracillis-cuneatus fasciculi (touch and vibration) correlates with ipsilateral clinical findings, whereas damage to unilateral spinothalamic tract (pain-temperature) correlates with contralateral clinical findings. Damage to commissural fibers correlates with a suspended bilateral "girdle" sensory level. Autonomic dysfunction is expected when there is bilateral cord involvement. (C) 2016 Elsevier Inc.
