Anatomical terminology |
Striated muscle tissue is muscle tissue that has repeating sarcomeres, in contrast with smooth muscle tissue. Specifically, striated muscles are:
- Skeletal striated muscle
- Branchiomeric muscle (embryologically different from skeletal muscle)
- Cardiac muscle (heart muscle)
Contractions in striated muscles are voluntary, except for the heart muscle, in which contractions are involuntary. Cardiac muscle is often treated separately from the other striated muscles, as it has somewhat different characteristics.[1]
Sarcomer is the functional unit of Striated muscles.

- Skeletal muscle atrophy is a pathological condition characterized by the loss of strength and muscle mass, an increase in myosin heavy chain (MHC) degradation and increase in the expression of two muscle-specific ubiquitin ligases: atrogin-1 and MuRF-1. Angiotensin II (AngII) induces muscle atrophy.

- Although skeletal muscle work efficiency probably plays a key role in limiting mobility of the elderly, the physiological mechanisms responsible for this diminished function remain incompletely understood. Thus, in the quadriceps of young (n=9) and old (n=10) subjects, we measured the cost of muscle

- MEF2 plays a profound role in the regulation of transcription in cardiac and skeletal muscle lineages. To define the overlapping and unique MEF2A genomic targets, we utilized ChIP-exo analysis of cardiomyocytes and skeletal myoblasts. Of the 2783 and 1648 MEF2A binding peaks in skeletal myoblasts an

- 1. 運動神経末端に活動電位が伝わると、神経末端周辺に局在する電位依存性Ca2+チャネルが開き、神経細胞内にCa2+が流入する。
- 2. 神経細胞内のCa2+濃度が上昇すると、シナプス顆粒が開口分泌され、神経伝達物質であるアセチルコリンがシナプス間隙に放出される。
- 3. アセチルコリンはシナプス間隙を経て筋細胞膜上のアセチルコリン受容体に結合する。
- 4. アセチルコリン受容体は陽イオンチャネルであり、一時的に陽イオンを透過させ、筋細胞膜を脱分極する。
- 5. アセチルコリンはアセチルコリンエステラーゼによりコリンに分解されて、神経細胞に取り込まれる。
- 6. 筋細胞で局所的な脱分極が起こると、周辺の電位依存性Na+チャネルが開き、脱分極が筋細胞全体に広がる。
- 7. 脱分極はT細管に伝わり、T細管に存在する電位依存性のタンパク質の構造を変化させ、筋小胞体の特殊な構造である終末槽上のCa2+放出チャネルを開く。
- 8. 筋小胞体中のCa2+が細胞質に拡散する。
- 9. ここで、筋収縮に関わるアクチンフィラメントにトロポミオシンとトロポニンが結合し、収縮開始を妨げているが、Ca2+がトロポニンに結合すると、トロポミオシンがアクチンフィラメント上で場所を変える。
- 10. この結果、トロポミオシンが覆い隠していたアクチンフィラメントのミオシン結合部位が露出する。
- 11. ミオシンはATPの加水分解のエネルギーを使って、アクチンフィラメントに結合できる構造をとり、アクチンに結合する。
- 12. ミオシンがアクチンフィラメントで首振り運動をすることで筋収縮が起こる。
