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 pelvic girdle is a solid box of bone: maximum security and ability to bear weight. The pectoral girdle is much more flexible, but less secure, comprising just the scapula, clavicle (if present), and proximal end of humerus. As such, it is more commonly injured, with less force, than the pelvic girdle.
Pelvic:
-Deep, secure socket for limb attachment
-Lightweight
-Weight-Bearing
Pectoral:
-Shallow socket for limb attachment
-Massive
-Flexibility
The pelvic girdle must support about 2/3 of your total wight,
the pectoral girdle just has to support your arms.
Yes, much more flexible than the pelvic girdle
pector girdle is more flexible
Pectoral girdle
Pectoral girdle is flexible while Pelvic girdle is rigid
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 upper limbs are attached to the axial skeleton by the pectoral girdle (which consists of the scapula and clavicle)
The part of the skeleton that includes the pectoral girdle and the pelvic girdle and the upper and lower limbs.
The appendicular skeleton is what makes up the limbs as well as the shoulder and pelvic girdles.

An appendicular skeleton is composed of 126 bones of the appendages, and pectoral and pelvic girdles.

pelvic gridles
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 upper limbs are attached to the axial skeleton by the pectoral girdle (which consists of the scapula and clavicle)
Pelvic Girdle: Deep synovial ball and socket joint surrounded by bone structure. This gives a trade off for security, rigidity with less flexibility due to its weight bearing role of full body weight. Doesn't need muscles to hold it in place.Pectoral Girdle: Shallow synovial ball and socket joint which needs muscles to hold the head of the humerous in place. The four rotator cuff muscles perform this including Teres minor, infraspinatous, supraspinatous and subscapularis. This trade off for a shallow ball and socket joint held in by muscles allows a highest range of motion of any joint in body but there is less security and ability to bear weight. Is quite common to dislocate shoulder joint but very uncommon to dislocate your hip joint.
shoulder and hip girdles
The pectoral girdle attach the upper limbs to the axial skeleton and also provides attachment points for several muscles that move the upper limbs. The girdles are very light, therefore, allows upper limbs a greater degree of movement, however, because only the clavicle attaches to the axial skeleton, the scapula move freely across the thorax, allowing the arm to move with it. This arrangement is good for flexibility, but does not provide stability: which causes shoulder dislocation in many instance.....Anatomy & Physiology (pg.198) ..EB
