Multiple Choice

When comparing the pelvic and pectoral girdles, which statement is incorrect?

The articulation between the pectoral girdle and the axial skeleton is smaller than the articulation between the pelvic girdle and the axial skeleton.

The socket of the hip joint is much deeper than the socket of the shoulder joint.

There are more individual bones in the pectoral girdle than the pelvic girdle.

The pelvic girdle allows for a greater range of motion than the pectoral girdle.

Verified step by step guidance

Understand the basic anatomy of the pelvic and pectoral girdles. The pelvic girdle consists of the hip bones (ilium, ischium, and pubis) and connects to the axial skeleton at the sacrum. The pectoral girdle consists of the clavicles and scapulae and connects to the axial skeleton at the sternum.

Compare the articulations: The pectoral girdle has a smaller and more flexible articulation with the axial skeleton, allowing for a wide range of motion in the shoulder. In contrast, the pelvic girdle has a larger and more stable articulation with the axial skeleton, providing support for weight-bearing.

Examine the joint sockets: The hip joint (acetabulum) is a deep socket that provides stability for weight-bearing and locomotion. The shoulder joint (glenoid cavity) is shallower, allowing for greater mobility.

Count the bones: The pectoral girdle has more individual bones (two clavicles and two scapulae) compared to the pelvic girdle (two hip bones).

Evaluate the range of motion: The pectoral girdle allows for a greater range of motion due to its flexible connection to the axial skeleton and the shallow shoulder joint. The pelvic girdle, being more stable, allows for less range of motion, which makes the statement about the pelvic girdle allowing greater motion incorrect.
