神経細胞極性 - 脳科学辞典

神経細胞は、一本の長い軸索と複数の短い樹状突起を伸ばし、高度に発達した細胞極性を形成する。このような神経細胞の極性は、シグナルの入力、統合、出力といった情報処理機能に重要な役割を果たす。これまでに神経細胞の極性化に関与する数多くの分子が同定され、極性化を担う細胞内外のシグナルのクロストーク、対称性の破れ、神経突起伸長のメカニクス、軸索や樹状突起に特異的に存在する分子の細胞内局在メカニズムに関して解析が進みつつある。目次 1 神経細胞極性とは 2 神経細胞の極性化の過程 2.1 軸索と樹状突起 2.2 培養神経細胞における極性形成 2.3 脳組織における極性形成過程 3 軸索の形成と伸長 3.1 軸索伸長におけるアクチンの役割 3.2 軸索伸長における微小管の役割

軸索：細胞の興奮を他の細胞に伝える（長さ 1mm-1m）樹状突起：他の神経細胞からの情報を受けとる脊椎動物は巨大な軸索をもたないが、運動神経の伝導速度は非常に速い：軸索はミエリンという薄い鞘（支持細胞からなる）で包まれている神経系神経細胞は複雑なネットワークを作り、受容器（情報を受け取る装置）と効果器（反応する装置）がある中枢神経系（脳と脊髄：信号を統合し、命令を伝える）と末梢神経系（中枢外の神経と神経節で、自律神経系と体性神経系）で構成自律神経系は交感神経系と副交感神経系で構成され、体性神経系は感覚神経、運動神経で構成中枢神経系大脳：情報を処理する中枢（記憶、判断など）間脳：視床は感覚神経の中継、視床下部は自律神経の中枢（体温、血圧など）

神経細胞の極性形成Top - 名古屋大学

神経細胞は1本の軸索と複数の樹状突起を有する。樹状突起は神経伝達物質受容体を介して受け取った情報を電気信号に変えて細胞体に伝え、軸索は他の細胞へ神経伝達物質を放出し情報を伝える。
