Question

Each pectoral girdle is made of

• A. Two innominates
• B. Two clavicles and two scapula
• C. One clavicle and one scapula
• D. Two clavicles and one scapula

Answer 1

Answer: (B)

Two clavicles and two scapula

• The pectoral girdle is formed of two halves. Each half of pectoral girdle consists of a clavicle and a scapula.
  
• 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.
• Hence each pectoral girdle is made of two clavicles and two scapulae.
• So, the correct answer is 'Two clavicles and two scapulae'.
