Hints & Solutions
(c) $11 th$ and $12 th$ pairs of ribs are not connected ventrally and are therefore, called floating ribs. Acromion is a flat expanded process of spine of scapula. The lateral end of clavicle articulates with acromion process. Scapula is a flat triangular bone in the dorsal part of the thorax between $2 n d$ and the $7 th$ rib. Glenoid cavity of scapula articulates with head of the humerus to form the shoulder joint.
The acromion of the scapula is a large bony projection on the superior end of the scapula. It is an important landmark of the skeletal system and a muscle attachment point essential to the function of the shoulder joint. The acromion also forms the acromian clavicular (AC) joint with the clavicle.
