The size and orientation of its functionally important features, including the deltoid tubercle, greater tubercle, and medial epicondyle, are pivotal to an animal's style of locomotion and habitat. In cursorial (running) animals such as the pronghorn , the deltoid tubercle is located about a quarter of the way down the shaft, which allows for ...
The deltoid muscle covers the top of each shoulder joint. This deltoid muscles workout uses dumbbells to improve posture, mobility, strength and shoulder injury risk. 15 deltoid exercises to tone ...
Shoulder anatomy, front view Shoulder anatomy, back view The rotator cuff is an anatomical term given to the group of four muscles and their tendons that act to stabilize the shoulder. [ 3 ] These muscles are the supraspinatus , infraspinatus , teres minor and subscapularis and that hold the head of the humerus in the glenoid cavity during ...
The lateral fragment of the clavicle during a fracture is depressed by the weight of the arm and is pulled downward by the strong abductor muscles of the shoulder joint, especially the deltoid. The part of the clavicle near the center of the body is tilted upwards by the sternocleidomastoid muscle. Children and infants are particularly prone to ...
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)
Some other common shoulder injuries are fractures to any shoulder girdle bones i.e. clavicle, ligamentous sprains such as AC joint or GH ligaments, rotator cuff injuries, different labral tears, and other acute or chronic conditions related to shoulder anatomy. Shoulder girdle pain can be acute or chronic and be due to a number of causes.
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.
A bone fracture of the shoulder involves a partial or total crack through one of the three bones in the shoulder, the clavicle, the scapula, and the humerus. The break in a bone usually occurs as a result of an impact injury, such as a fall or blow to the shoulder. Fractures usually involve the clavicle or the neck (area below the ball) of the ...
