ARM BONES Meaning and
Definition
-
Arm bones refer to the set of long bones that form the structural framework of the upper limbs in humans and other vertebrates. In human anatomy, the arm bones specifically refer to the bones present between the shoulder and the elbow, namely the humerus, radius, and ulna.
The humerus is the largest bone in the upper arm, extending from the shoulder joint to the elbow joint. It is situated between the scapula (shoulder blade) and the radius and ulna of the forearm. The humerus provides support and offers attachment sites for various muscles that facilitate arm movement.
The radius and ulna are the bones of the forearm. The radius lies on the lateral side of the forearm and contributes to wrist joint movement, along with supporting the hand's rotation and flexion. The ulna is positioned medially and is slightly longer than the radius. It functions primarily in the flexion and extension of the forearm.
Together, these arm bones function to anchor muscles, facilitate joint movements, and provide stability and strength to the upper limbs. They also play a crucial role in supporting daily activities such as lifting, carrying, throwing, and manipulating objects.
In summary, arm bones represent the bones present in the upper limbs, specifically the humerus, radius, and ulna. These bones work together to enable various movements and provide the necessary structural support for the arms.

Etymology of ARM BONES
The term "arm bones" does not have a specific etymology because it is a combination of two common English words.
The word "arm" can be traced back to the Old English word "earm", which means "forelimb". This, in turn, derives from the Proto-Germanic word "armaz" and the prehistoric Indo-European root "h₂érgh" meaning "to rise, to be on the upper side". The term evolved over time and became "arm" in modern English.
The word "bones" is derived from the Old English word "ban", which means "bone". This word has its roots in the Proto-Germanic word "bainam" and the prehistoric Indo-European root "ost" meaning "bone". It underwent various changes over time and eventually became "bones" in present-day English.
