椎弓根(pedicle of vertebral arch)是人體脊柱解剖學中的關鍵結構,屬于椎弓(vertebral arch)的重要組成部分。椎弓由椎體後方延伸出的骨性結構構成,與椎體共同圍成椎孔(vertebral foramen),而椎弓根作為連接椎體與椎闆(lamina)的短而粗的骨柱,其具體特征包括:
解剖位置與形态
椎弓根位于椎體的後外側,左右各一,呈圓柱狀。其上方和下方分别形成椎上切迹(superior vertebral notch)和椎下切迹(inferior vertebral notch),相鄰椎骨的切迹組合構成椎間孔(intervertebral foramen),為脊神經和血管提供通道(來源:Gray's Anatomy, 第42版)。
功能與生物力學
椎弓根是脊柱力學負荷傳遞的核心結構,承擔着将後方椎弓受到的應力(如肌肉收縮、重力負荷)傳導至前方椎體的作用。其骨密度較高,尤其在胸椎和腰椎區域,可承受較大的壓縮和剪切力(來源:PubMed Central, 生物力學研究文獻)。
臨床相關性
在脊柱外科手術中,椎弓根是螺釘植入的常用錨定點。例如腰椎椎弓根螺釘内固定術需精确測量椎弓根的寬度、高度及角度,以避免損傷脊髓或神經根(來源:Mayo Clinic 脊柱手術指南)。此外,椎弓根骨折或腫瘤侵犯可能引發神經壓迫症狀,需通過CT或MRI進行詳細評估(來源:Radiopaedia 影像學數據庫)。
“pedicle of vertebral arch”是一個解剖學術語,指椎弓根,屬于椎骨結構的一部分。以下是詳細解釋:
椎弓(vertebral arch)
椎弓是椎骨後方的弓形骨結構,由兩側的椎弓根(pedicle)和椎闆(lamina)構成,與椎體共同圍成椎孔,保護脊髓。它的英文對應詞為“vertebral arch”,在解剖學中常簡稱為“神經弓”。
椎弓根(pedicle)
整體結構關系
椎弓根(pedicle)與椎闆(lamina)共同構成椎弓(vertebral arch),而椎弓又與椎體(vertebral body)組合形成單個椎骨的完整結構。這種結構在脊柱運動中承擔負荷并保護神經組織。
詞源與翻譯
椎弓根(pedicle of vertebral arch)是椎骨中連接椎體與椎弓的關鍵結構,具有重要解剖和臨床價值。
