I just had this on my homework.
The answers for Pectoral are A. Flexibility, C. Lightweight, D. Shallow socket for limb attachment.
For Pelvic, B. Massive, E. Deep, secure socket for limb attachment, F. Weight-bearing.
Hope that helps!
The pelvic girdle and the thoracic girdle. You are familiar how a body girdle goes around the body. These are the same. They make a girdle around the chest and around the pelvis.
The extremities, such as the arms and legs, are attached to the axial portion of the body through joints. The arms are attached to the axial skeleton through the shoulders, while the legs are attached through the hips. These joints allow for movement and flexibility.
Flexibility: pectoral girdle is more flexible-less ligaments, ball and socket joint is shallower Security: pelvic girdle is more secure, deeper socket. there are more dislocated shoulders than dislocated hips ability to bear weight: pelvic girdle can bear more weight-the pelvic girdle has bones that are fused (os coxa) and a joint with the sacrum. the pectoral girdle has a little bone called the clavicle connecting it to the body wall.
The pectoral fin on a shark helps with steering and stability while swimming.
The appendicular skeleton is the component of the skeletal system that consists of the upper and lower limbs, as well as the pelvic and shoulder girdles. This part of the skeleton is involved in movement and provides stability and support to the body.

The appendicular skeleton is composed of 126 bones, including those of the upper and lower limbs as well as the pectoral and pelvic girdles. These bones are important for movement and provide connections to the axial skeleton.
The pectoral girdle is formed by the scapula, the humerus and the clavicle 3 bones in total

The weight of an amphibian's body is transferred to the limbs by using the pectoral and pelvic girdles.

The descriptive features of the humpback whale include two blowholes and notched flukes (tail). The pectoral fins are 1/3 the length of the animal and are the largest flippers of any whale.

shoulder and hip girdles
Weight-bearing is most important in the pelvic girdle. The pelvic girdle is located at the base of the spine and pelvis, and it supports the weight of the upper body and provides stability for movements such as walking and standing. In contrast, the pectoral girdle is mainly involved in supporting the arms and shoulders.
The pectoral girdle is made up of a left pectoral girdle and a right pectoral girdle. Each set of pectoral girdles has two bones, one clavicle and one scapula. The clavicle bones on both the left and right pectoral girdles are articulated with the sternum. The clavicles are also found on the anterior or front part of the skeleton. The scapula bones on both the left and right pectoral girdles are part of the posterior appendicular skeleton. The scapula bones each articulate with clavicle and the humerus. Your pectorial girdle is located at your shoulder area on your appendicular skeleton. Your upper limb bones are attached to the pectoral (shoulder) girdle. dcart45.
They dont wear girdles they wear pants
