Advantages of hollow bones : Lighter Requires less calcium and phosphorous for its formation. The pectoral girdle is larger but does not bear much weight, while the pelvic girdle is lightweight but weight-bearing. Pectoral girdle Pelvic girdle: 1. Difference between Pectoral and Pelvic Girdle 1. 95, 96), that is, in the oldest known reptiles, the pectoral girdle is composed of eleven separate and distinct bones, at least in early life: the median interclavicle and a . Absence of clear articular surfaces on the clasper and girdle in the Arthrodira, along with evidence from the Ptyctodontida, suggest that these are separate structures along the body. The pelvic girdle is situated in the pelvic region of the body and joins the lower limb to the body. 2. Comparison and Differences. 1. Aquatic vertebrates have smaller pelvic girdles . rigid girdle . The pectoral girdle is a component of the appendicular skeleton, which is responsible for supporting the upper limbs of the body. The pectoral girdle is part of the appendicular skeleton . This girdle attaches the hind limb with the backbone and bears the weight of the body. with water buoyancy which held aquatic. 3. pectoral: relatively small. What is the difference between the pelvic girdle and pectoral girdle? to be able to . Pectoral girdle supports forelimbs' bones (humerus, ulna, radius, carpels, meta carpels and phalanges). Pelvic girdle has attachment with the muscles of the hips. The pelvic girdle of lobe-finned fish is composed of a crescentric pubis often connected through cartilage at the midline, . Pelvic Girdle: The pelvic girdle is also formed of two equal halves or os-innominate. Moreover, there are few comparative developmental studies.

The portion of the skeleton that consists of the bones of the pectoral girdle, the pelvic girdle, the upper limbs, and the lower limbs. and pectoral girdles compared to their body size.-This is because their body weight is supported. The pelvic girdle is situated in the pelvic region of the body and joins the lower limb to the body. The biggest differences in the pelvises of men and women are the sizes of the pelvic inlet, sciatic notch and the angle of the two pubic bones that meet at the front. Anatomists classify this bone as a flat bone . The key difference between pelvis and pelvic girdle is that the pelvis is a lower part of the trunk that composes several bones such as a pair of bones, sacrum and coccyx while the pelvic girdle is one of the two parts of the bony pelvis that composes two appendicular hip bones oriented in a ring.. Conversely, the left and right pelvic girdles unite to form a strong foundation for the upper and lower body movement. 4. Tetrapods - early ones had pectoral girdle similar to those of early bony fishes, but lost posttemporal & acquired interclavicle (which still occurs in several amniotes, e.g., alligator, birds, & monotremes) Clavicle & coracoid - one or both typically brace scapula against sternum (as in birds; below) Pectoral Girdle vs. Pelvic Girdle. 2.
