The scapula is a large triangular flat bone situated in the dorsal part of the thorax between
A) Second and seventh rib
B) Third and fourth rib
C) Fifth and sixth rib
D) Second and fifth rib

Hint:The rib cage which is also known as thoracic cage in humans is the arrangement of ribs to the vertebral column and sternum in the thorax that serves as protection against the lungs and heart.

Complete answer
Rib cage comprises -24 ribs that are arranged in 12 pairs, the 12 thoracic vertebrae, the costal cartilages and the sternum and xiphoid process. Ribs are broadly classified into true ribs and false ribs. True ribs are those that are directly attached to the sternum and false ribs are those that are not directly attached to the sternum. A rib typically consists of head, neck and shaft; head is the portion which is closest to the vertebra it attaches to the neck is flattened and extends from the head and the remaining part of the rib makes up the shaft. Now coming to the scapula, it is also known as the shoulder bone and is located between the second and seventh rib and connects the upper arm bone or humerus with the collarbone or clavicle.

So the correct answer is option (A) Second and seventh rib.

Note:Scapula helps in movement through six types of actions which are- elevation, depression, retraction, protraction, upward rotation and downward rotation. These movements are brought by different muscles that are attached to the scapula, few of which are trapezius, deltoid, pectoralis minor, etc.
