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 girdle (shoulder girdle) is more flexible than the pelvic girdle due to its greater range of motion and flexibility in various directions. The pelvic girdle is more stable and less mobile to provide support for the lower body during weight-bearing activities.
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.

What are the 2 girdles of human body?
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.
What are Descriptive terms for the pectoral girdles?
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!
How are the extremities attached to the axial portion of the body?
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.
Which component of the skeletal system is made up of the upper and lower limbs and the pelvic and shoulder girdles?
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 includes the bones of the what?
The appendicular skeleton includes the bones of the limbs (arms and legs), the shoulder girdle, and the pelvic girdle. It provides support and facilitates movement of the body.
How many bones does the pectoral girdles have?
23
What skeleton is composed of 126 bones of the appendages and pectoral and pelvic girdles?
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.
What bones are included in each of pectoral and pelvic girdles?
The pectoral girdle is formed by the scapula, the humerus and the clavicle 3 bones in total

How is the weight of an amphibian's body transferred to the limbs?
The weight of an amphibian's body is transferred to the limbs by using the pectoral and pelvic girdles.
Compare the pectoral and pelvic girdles by choosing appropriate descriptive terms from the key?
The pectoral girdle is lighter and more mobile, with less bony connection to the axial skeleton, providing greater range of motion in the upper body. The pelvic girdle, on the other hand, is heavier and more stable, designed to support the body's weight and provide a strong base for lower body movements.
How are the extremities attached to the axial portion of the body?
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.
How to Compare the pectoral and pelvic girdles in terms of flexibility range of motion allowed security and ability to bear weight?
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.
Does the pectoral girdle have secure or insecure limb attachments?
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
Where is the weight-bearing most important in pectoral or pelvic 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.
What are the two pairs of girdles in your body?
shoulder and hip girdles
