The T9 - T12 are part of the twelve vertebrae that make up the thoracic section of the spinal column, which lies between the cervical and lumbar regions. Other thoracic vertebrae names that these four vertebrae are known by include “transition vertebrae” since they descend into the lumbar spinal column.

Complete injuries result in the total loss of movement and sensation below the point of injury, while incomplete injuries indicate that some function below the level of injury is retained. Survivors with T-9 to T-12 injuries typically have control of their hands and arms, as well as good control of their abdominal muscles and trunk.

The thoracic spine has 12 nerve roots (T1 to T12) on each side of the spine that branch from the spinal cord and control motor and sensory signals mostly for the upper back, chest, and abdomen.

2017年11月10日 · 胸椎神经属于「内脏中神经」（T8—T12）：分布于腹腔及肠系膜上器官，负责肾、大肠、膀胱等器官，若此段神经压迫，将引起这些器官发生问题，较常见的症状为两脚水肿、尿频及消化不良等症状 。 . 上图 胸椎示意图 （a）T6上面观 （b）T6侧面观 （c）T7～9后面观

T9椎体属于胸椎部椎体，胸椎一共12块椎体，分别为T1-T12，其中T1-T4被称为上4块，T5-T8被称为中4块，T9-T12被称为下4块。 T9椎体上接T8椎体，下承T10椎体，属于胸椎的下4块，接近腰椎部。 T9椎体与T8、T10共享一个肋软骨，可以支撑肋软骨，有助于肋软骨保护身体的重要脏器，还有助于稳定脊椎，支撑身体。 [1]Jutta Hochschild.肌骨关节功能解剖图解 [M].济南.山东科学技术出版社.2019.515. [2]沃纳·普拉策编著.人体解剖学彩色图谱 运动系统 [M].******.上海科学技术出 …

2022年3月29日 · 表现为脊髓病变平面以下同侧肢体瘫痪和深感觉障碍，对侧痛、温度觉障碍，称为布朗一塞卡尔综合征 (Brown-Sequard syndrome)，又称为脊髓半切综合征。 多见于脊髓肿瘤的早期：，病变节段平面以下同侧肢体还有血管舒缩运动功能障碍。 皮肤初期潮红、发热，后期为发绀、发冷，这是由于侧索中下行的血管舒缩纤维被阻断的缘故，并非脊髓半侧损害均有这些症状。 2 脊髓横贯性损害. 出现损害平面以下各种运动、感觉和括约肌功能障碍。 同时当脊髓的某些节 …

The T9, T10, T11, and T12 vertebrae form the base of the thoracic spine. The thoracic spine is made up of 12 segments total between the cervical and lumbar levels. Sections T9 - T12 are known as transition vertebrae because of their proximity and similarity to the lumbar vertebrae.

Degenerative thoracic stenosis has been shown to most frequently involve the lower thoracic segments (T9-T12) where there is greater mobility and vulnerability due to flexion, extension and rotation of the spine. The thoracolumbar junction is ...

2023年10月13日 · 内脏小神经(t9-t12)：分布于腹腔及肠系膜上器官，负责肾、大肠、膀胱等器官。 若此段神经压迫，将引起这些器官发生问题，较常见的症状为两脚水肿、尿频及消化不良等症状。

C1-4与同序数椎骨完全对应，C5-8与T1-4与同序数椎骨上1位椎骨对应，T5-8与同序数椎骨上2位椎骨对应，T9-12与同序数椎骨上3位椎骨对应,5个腰节对应10-12椎骨，所有骶节尾节对应第一腰椎。 脊髓圆锥以下脊神经叫马尾，所腰椎穿刺在3-4,4-5，避免损伤脊髓。 脊髓节段与椎骨的对应关系脊髓节段相应的椎骨，推算举例：上颈髓C1～C4与相应椎骨（体）同高C3平对第3颈椎下颈髓C5～8。 上胸髓T1～4较同序数椎骨高1个椎骨（体）C5平对第4颈椎中胸髓T5～T8较同序数 …
