Scapula is a large triangular flat bone situated in the dorsal part of the thorax between
A) The second and fifth ribs
B) The second and seventh ribs
C) The third and sixth ribs
D) The third and eighth ribs

Hint: Scapula is also known as shoulder bone,shoulder blade,wing bone.It is located in the upper thorax region.It connects the upper arm bone with the collar bone.

Complete Answer:
Let’s define the scapula first and find the location of the bone-
1) Scapula is the large triangular bone that helps in formation of the shoulder joint. It is present in the dorsal part of the upper thorax.
2) It is concave and is directed medially and forwards. It is marked by 3 longitudinal ridges. A thick ridge adjoins the lateral border. This part of the bone is almost rod-like and acts a lever for the action of serratus anterior in overhead abduction of the arm. Dorsal Surface-The prominent spine of the scapula divides the surface into a smaller supraspinous fossa and a larger infraspinous fossa. The depth of the supraspinous fossa is filled by the supraspinatus muscle.
3) Normally, the scapula rests at a position on the posterior thorax approximately 2 inches from the midline, between the second through seventh ribs.

Additional Information:The scapula contains 3 borders.
1) Superior Border-It is thin and shorter.
2) Lateral Border- This is thick and presents in an infraglenoid tubercle at the upper end. The lateral or axillary border runs from the inferior angle to the lateral angle of the scapula.
3) Medial Border- This is thin and extends from superior to inferior angle. With the arm resting by the side, the medial or vertebral border runs almost parallel to the spinal column.

Hence, the correct option is B (The second and seventh ribs).

Note:The scapula also articulates with the humerus at the glenohumeral joint, and with the clavicle at the acromioclavicular joint.
