Chapter 38: Q. 5 (page 1119)

The pectoral girdle consists of the:

  1. clavicle and sternum
  2. sternum and scapula
  3. clavicle and scapula
  4. clavicle and coccyx

Short Answer

Expert verified

The correct answer is option (c).

The pectoral girdle consists of clavicle and scapula.

Step by step solution

01

Pectoral girdle

  • Your upper limbs are attached to the bones along your body's axis by a pectoral girdle, also known as the shoulder girdle.
  • It is the group of bones that attaches the arm to the rest of the skeleton.
  • It offers support and strength so that the shoulder can move.
02

 Step: 1 Explanation for Correct answer

  • The clavicle and scapula are the two bones that make up the pectoral girdle.
  • The shoulder's rear region contains the scapula, also referred to as the shoulder blade. It facilitates articulation with the humerus bone and collarbone.
  • The clavicle, also referred to as the collarbone, is located anterior to the shoulder. Thus, the option c is correct.
03

Step: 2 Explanation for incorrect answer

  • Humans have clavicles that connect the sternum (breastbone) medially and the scapulae laterally. The scapulae are only connected to the trunk by muscles, however, therefore neither joint is clavicular. So, options a and b are wrong.
  • The coccygeal bones are the end of the five vertebrae in the vertebral column, which join to form the tailbone, or coccyx. . Hence, option d is wrong too.
