💪🏾 Rotator Cuff Muscles – Your Shoulder’s Stability Squad 🦴
💪🏾 肩袖肌肉 – 肩膀的稳定性团队 🦴
The rotator cuff is a group of 4 muscles that play a key role in stabilising and moving the shoulder joint. Whether lifting weights 🏋️, throwing a ball 🎾, or reaching for that jar on the top shelf, these muscles are hard at work!
肩袖是一组 4 块肌肉，在稳定和移动肩关节中起着关键作用。无论是举重🏋️、扔球🎾还是伸手去拿最高层的罐子，这些肌肉都在努力工作！
Meet the Team:（认识团队）
1️⃣ Supraspinatus – Located at the top of the shoulder blade, it initiates arm abduction (lifting your arm out to the side) and helps with shoulder stability.
1️⃣ 冈上肌 - 位于肩胛骨顶部，它启动上臂外展（将手臂抬起至侧面）并有助于肩部稳定性。
2️⃣ Infraspinatus – Found on the back of the shoulder blade, it’s responsible for external rotation of the arm and stabilising the joint during movement.
2️⃣ 冈下肌 - 位于肩胛骨背面，负责手臂的外旋和在运动中稳定关节。
3️⃣ Teres Minor – A small but mighty muscle along the edge of the scapula. It also supports external rotation and works with the infraspinatus to keep your shoulder steady.
3️⃣ 小圆肌 - 位于肩胛边缘的一个小而强大的肌肉。它还支持外旋，并与冈下肌协同作用，以保持肩部稳定。
4️⃣ Subscapularis – Hiding on the front of the scapula, this muscle controls internal rotation and ensures your shoulder remains stable during complex movements.
4️⃣ 肩胛下肌 – 隐藏在肩胛骨前方，该肌肉控制内旋并确保在复杂运动中肩部保持稳定。
Did you know? 你知道吗？
Blood Supply: The supraspinatus tendon has a relatively poor blood supply, meaning it takes longer to heal after injury compared to other tissues.
血液供应：肩袖肌腱的血液供应相对较差，这意味着受伤后与其他组织相比，恢复时间更长。
Why does supraspinatus have a poor blood supply?
为什么肩袖上肌血供差？
🌊 Watershed Zone（分水岭区）
The area where the supraspinatus tendon attaches to the bone has what’s known as a watershed zone—a region with minimal blood supply. This lack of consistent blood flow makes it harder for the tissue to repair itself after injury or overuse.
肩袖肌腱附着于骨骼的区域有一个被称为分水岭区的区域——一个血供极少的区域。这种持续的血流不足使得组织在受伤或过度使用后更难自我修复。
Together, these muscles maintain balance between flexibility and strength, preventing injuries and ensuring smooth, pain-free movements. Keep them healthy through strengthening and mobility exercises to avoid shoulder issues! 🚀
这些肌肉共同维持柔韧性和力量之间的平衡，预防受伤并确保运动顺畅、无痛。通过加强和灵活性练习保持它们的健康，以避免肩部问题！🚀
