the lumbar region encompassing the lower back. the sacral region occurring at the end of the spine, directly above the buttocks. The regions of the back of the arms, from superior to inferior, include the cervical region encompassing the neck, the acromial region encompassing the shoulder, the brachial region encompassing the upper arm,
It involves an articulation between the glenoid fossa of the scapula (shoulder blade) and the head of the humerus (upper arm bone). Due to the very loose joint capsule , it gives a limited interface of the humerus and scapula, it is the most mobile joint of the human body.
The scapula (pl.: scapulae or scapulas [1]), also known as the shoulder blade, is the bone that connects the humerus (upper arm bone) with the clavicle (collar bone). Like their connected bones, the scapulae are paired, with each scapula on either side of the body being roughly a mirror image of the other.

While ...
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 intricate anatomy of the back provides support for the head and trunk of the body, strength in the trunk of the body, as well as a great deal of flexibility and movement. The upper back has the most structural support, with the ribs attached firmly to each level of the thoracic spine and very limited movement.
