Question

Two halves of pectoral girdle fuse in

• A. Lateral sides
• B. Mid-dorsal sides
• C. Mid-ventral line
• D. Both dorsal and ventral lines

Answer 1

Answer: (C)

Mid-ventral line

• A pectoral girdle or shoulder girdle attach the bones of upper limb to the axial skeleton.
  
• Each pectoral girdle is formed of two halves. Each half of pectoral girdle consists of a scapula and clavicle. The Scapula articulates with the clavicle and Humerus. The clavicles or collar's bones are slender, doubly curved long bones, which articulate with the sternum.
• Two halves of pectoral girdle (left and right half) fuse in mid-ventral line.
  
• So, the correct answer is 'Mid ventral line'.
