Muscles Of Hand – FAQ
The primary muscles of the hand are divided into two groups: intrinsic and extrinsic muscles. Intrinsic muscles are located within the hand itself and include the thenar, hypothenar, lumbricals, and interossei muscles. Extrinsic muscles, originating from the forearm, include the flexor and extensor muscles that control finger movements.
Intrinsic muscles of the hand enable fine motor skills and intricate movements. The thenar muscles control thumb movements, while the hypothenar muscles manage the little finger. The lumbricals help in flexing the metacarpophalangeal joints and extending the interphalangeal joints. Interossei muscles aid in finger abduction and adduction.
Extrinsic muscles are crucial for gross hand movements and grip strength. These muscles, originating from the forearm, include the flexor digitorum superficialis and profundus, which flex the fingers, and the extensor digitorum, which extends the fingers. They work in coordination with intrinsic muscles for complex hand functions.
Preventing hand muscle injuries involves regular stretching, strengthening exercises, and proper ergonomics. Warm-up routines before engaging in activities and using protective gear can also help. It’s crucial to take breaks during repetitive tasks to avoid overuse injuries.
Common conditions include carpal tunnel syndrome, tendonitis, and Dupuytren’s contracture. Carpal tunnel syndrome involves pressure on the median nerve. Tendonitis results from inflammation of the tendons, while Dupuytren’s contracture causes thickening of the tissue under the skin of the palm, leading to bent fingers. These conditions often require medical intervention for proper management.
