The pelvic girdle is not considered massive in terms of size or weight compared to other skeletal structures, but it is robust and sturdy. It consists of the ilium, ischium, and pubis, which form a strong bony ring that supports the weight of the upper body and allows for bipedal locomotion. Its strength is essential for bearing stresses during activities such as walking, running, and lifting. Overall, while it is designed for durability rather than mass, its structural integrity is vital for mobility and stability.
The pectoral girdle is typically lighter in weight compared to the pelvic girdle. This is because the pectoral girdle is designed for more flexibility and mobility in upper body movements, while the pelvic girdle provides support and stability to the lower body.
No, the femur does not insert into the pelvic girdle at the patella. The femur connects to the pelvic girdle at the acetabulum, which is located in the hip bone. The patella, or kneecap, is a bone that sits in front of the knee joint and provides protection and leverage for the quadriceps muscle, but it is not involved in the connection between the femur and the pelvic girdle.

True. The wider and more massive pelvic girdle in women allows for easier passage of a baby during childbirth. The distance between the iliac crests is greater in women to accommodate the increased width needed for the birth canal.
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 pelvic girdle is generally considered to be massive due to its sturdy structure and its role in supporting the weight of the upper body. Its design helps to provide stability and protection for the internal organs within the pelvic cavity.
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 does not include the sacrum and coccyx, which are part of the axial skeleton.
In comparison to a male pelvic girdle, a female pelvic girdle typically has a wider pelvic inlet and wider pubic angle, allowing for childbirth. Additionally, the female pelvic bones are generally lighter and thinner than those of a male.
