Regional Anatomy of the Limbs and Its Clinical Application
摘要
The four limbs, divided into upper and lower, are connected to the trunk. For humans, upright walking and labor have transformed upper limbs into organs, not only providing functional support but also mastering tools. The lower limbs mainly function to support body weight and make movements. Anatomically, the upper limbs consist of lighter bones, thinner and looser joint capsules, and more slender muscles than the lower limbs.
