The deltoid tubercle of spine of scapula is a prominence on the spine of scapula. The spine, at lateral to the root of the spine, curves down and laterally to form a lip. [1] This lip is called the deltoid tubercle.
In human anatomy, the deltoid tuberosity is a rough, triangular [1] area on the antero lateral (front-side) surface of the middle of the humerus. [2] It is a site of attachment of deltoid muscle . [ 2 ]
The clavicle, collarbone, or keybone is a slender, S-shaped long bone approximately 6 inches (15 cm) long [1] that serves as a strut between the shoulder blade and the sternum (breastbone). There are two clavicles, one on each side of the body. The clavicle is the only long bone in the body that lies horizontally. [2]
The deltoid muscle covers the shoulder joint on three sides, arising from the front upper third of the clavicle, the acromion, and the spine of the scapula, and travelling to insert on the deltoid tubercle of the humerus. [3]
The deltoid tuberosity is a roughened surface on the lateral surface of the shaft of the humerus and acts as the site of insertion of deltoideus muscle. The posterorsuperior part of the shaft has a crest, beginning just below the surgical neck of the humerus and extends till the superior tip of the deltoid tuberosity.
The deltoid muscle is the muscle [1] forming the rounded contour of the human shoulder. It is also known as the 'common shoulder muscle', particularly in other animals such as the domestic cat. Anatomically, the deltoid muscle is made up of three distinct sets of muscle fibers, namely the anterior or clavicular part (pars clavicularis)
The shoulder girdle or pectoral girdle is the set of bones in the appendicular skeleton which connects to the arm on each side. In humans, it consists of the clavicle and scapula; in those species with three bones in the shoulder, it consists of the clavicle, scapula, and coracoid.
