Final answer:
Technically, the term 'palm' doesn't have a specific medical term, but the region is associated with the metacarpal bones, which are the long bones forming the palm, numbered 1 to 5 starting with the thumb side.
Step-by-step explanation:
The technical or medical term for the palm of your hand is not specifically designated by a single term, rather it involves the region and structures that comprise it. This includes the five metacarpal bones that form the structure of the palm.
They are located between the carpal bones of the wrist and the bones of the fingers and thumb. Each metacarpal bone is associated with one of the fingers or the thumb, and they are numbered from 1 to 5 starting on the lateral side (the side with the thumb). When discussing injuries, disorders, or surgery related to the palm, health care providers will typically reference these metacarpal bones along with associated soft tissues rather than using a separate term for the palm itself. As such, metacarpal is often the keyword used to denote issues or anatomy of the palm region.
