ANATOMY

Detailed explanation-1: -The humerus is the arm bone between your shoulder and your elbow.

Detailed explanation-2: -Etymology. The word “humerus” is derived from Latin: humerus, umerus meaning upper arm, shoulder, and is linguistically related to Gothic ams shoulder and Greek ōmos.

Detailed explanation-3: -If the capitulum is facing the right side or is present on the right side of the bone then it is the right humerus bone. If the capitulum is present on the left side of the bone then it is the left humerus bone. The location of the capitulum helps in differentiating the right and left humerus bone.

Detailed explanation-4: -The end of the humerus or upper arm bone forms the ball of the shoulder joint. An irregular shallow cavity in the scapula called the glenoid cavity forms the socket for the head of the humerus to fit in. The two bones together form the glenohumeral joint, which is the main joint of the shoulder.

Detailed explanation-5: -Most humerus fractures happen where the humerus meets the shoulder.
