THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The dorsal surface divides into two unequal parts via the scapular spine which runs across from the posterior scapula before forming the acromion. Above the spine is the supraspinous fossa and below it is the infraspinous fossa.

Detailed explanation-2: -The back of the scapula (also called the dorsal or posterior surface) is arched from above downward, and is subdivided into two unequal parts by the spine of the scapula. The portion above the spine is called the supraspinous fossa, and that below it the infraspinous fossa.

Detailed explanation-3: -Musculoskeletal practitioners commonly use contiguous bony landmarks to locate spinal levels. One such landmark is the inferior angle of the scapula (IAS), which is said to correlate with the T7, T8, or T9 spinous process or spinal level, depending on the source.
