Generality
The humerus is the even bone of the human body that makes up the skeleton of each arm.
Located between the scapula (main shoulder bone) and forearm bones (radius and ulna), it participates in the formation of two important joints of the upper limb: the shoulder joint and the elbow joint.
The proximal end is the portion closest to the scapula and with which it articulates, through a section called the head.
The body is the portion between the two epiphyses and in which various arm muscles are inserted.
Finally, the distal end is the portion adjacent to the ulna and radius, the bones with which it forms the elbow joint.
So is the humerus
The humerus is the even bone of the human body that makes up the skeleton of each arm.
The arm is the anatomical region of the upper limb between the shoulder, above, and the forearm, below.
Belonging to the category of long bones, the humerus forms two joints: one on the side of the shoulder, called the glenohumeral joint (or more simply the shoulder joint), and one on the side of the forearm, called the elbow joint.
IN THE "LOWER LIMB IT CORRESPONDS TO ...
In the lower limb, the bone corresponding to the humerus is the femur. The femur is the even bone which, alone, makes up the skeleton of each thigh.
Anatomy
Anatomical experts identify three major bony regions (or portions) in the humerus: the proximal end (or proximal epiphysis), the body (or shaft) and the distal end (or distal epiphysis).
