Step by step solution

Pectoral Girdle Functions

The pectoral girdle consists of the clavicle and scapula and connects the upper limb (arm) to the axial skeleton (trunk). Its main functions include providing support and allowing for various movements of the upper limb. Step 2: Analyze the pelvic girdle

Pelvic Girdle Functions

The pelvic girdle is formed by the fusion of the ilium, ischium, and pubis bones and forms the base of the spine. The pelvic girdle connects the lower limb (leg) to the axial skeleton and provides support, stability, and movement for the lower limbs. Step 3: Compare the functions of the pectoral and pelvic girdles

Comparison of Functions

From the analysis of the functions of the pectoral and pelvic girdles, it can be seen that the pectoral girdle, connecting the upper limb to the axial skeleton, allows for a wide range of movements and flexibility, while the pelvic girdle, connecting the lower limb to the axial skeleton, is more specialized for weight-bearing and stability. Step 4: Determine the validity of the statement

Statement Assessment

The statement "The pectoral girdle is specialized for weight-bearing, while the pelvic girdle is specialized for flexibility of movement" is incorrect. It should be the other way around. The pectoral girdle is specialized for flexibility of movement, while the pelvic girdle is specialized for weight-bearing. Therefore, the statement is False (F).
