In a tetrapod vertebrate, the term "upper limb" includes the scapula, humerus, radius, ulna, carpals, metacarpals, and phalanges.

In formal usage, the term "arm" refers specifically to the segment between the shoulder and elbow, consisting of the humerus bone.

The term "arm" is a part of the "upper limb", which includes the entire limb from the shoulder to the fingertips.

In informal anatomy, the term "upper arm" refers to the region between the shoulder and elbow, which includes the humerus bone and surrounding soft tissues.

In the human body, the muscles of the upper limb can be classified into two groups: extrinsic muscles (originating from the torso and inserting into the upper limb) and intrinsic muscles (originating and inserting within the upper limb).
