Hand movements are controlled by two main groups of muscles — extrinsic muscles and intrinsic muscles. Both work together to provide strength, precision, and coordination. 1️⃣ Extrinsic Muscles (Power & Force Movements) Crude or forceful hand movements are controlled by muscles that run along the forearm. These are known as the extrinsic muscles of the hand. ✔ Located in the forearm ✔ Connected to hand bones via long tendons ✔ Responsible for gripping, lifting, and strong movements As these tendons pass over the wrist joints, they are surrounded by lubricated tendon sheaths to reduce friction. They are also held in place by strong retaining bands (retinaculum) to prevent displacement during movement. 2️⃣ Intrinsic Muscles (Fine & Precise Movements) Smaller and more delicate hand movements are controlled by intrinsic muscles, which are located within the hand itself. ✔ Attach directly to the carpal and metacarpal bones ✔ Do not extend significantly beyond the knuckles ✔ Control precise finger coordination (writing, buttoning, typing) These muscles connect to the fingers via tendons and allow accurate, controlled movements. Why This Matters? Damage to tendons, nerves, or muscles due to: * Trauma * Fractures * Tendon injuries * Nerve compression (like carpal tunnel syndrome) Can affect hand strength and fine motor control. Early diagnosis and proper orthopaedic care are essential for full recovery.
