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 pectoral and pelvic girdle is formed by much expanded, ventrally, flat-lying bones (scapula, coracoid, pubis, ischium). The right and left hip bones also converge anteriorly to attach to each other. 1. Bird anatomy-Wikipedia. The pectoral girdle is larger but does not bear much weight, while the pelvic girdle is lightweight but weight-bearing.

QUE: Compare and contrast the skeletal structure of pectoral and pelvic limbs The difference between pectoral and pelvic limb is that pelvic limb is composed of two pelvic bones that attach in the back of the sacrum and these are joined in the front at the pubic symphysis, which is composed of cartilages whereas the pectoral limb is composed of scapulae and clavicles which joins the scapula . Both the halves are joined together mid-ventrally by pubic symphysis to form a stout and strong girdle situated in the pelvic region between the two hindlimbs. Pelvic girdle has attachment with the muscles of the hips. Sketch and label the pectoral girdle of humans. Also read COMPARATIVE ANATOMY: Pectoral Girdle of Fish and Frog. Pelvic girdle. This girdle looks like English letter 'V". Moreover, there are few comparative developmental studies. Various authors have proposed alternative bottlenecks during evolution for the pectoral-pelvic similarity [reviewed in (7, 23)]; these evolutionary bottlenecks represent times when pectoral and pelvic appendages showed the greatest anatomical similarity to each other (i.e., their . 2. It is composed of two bones namely clavicle or collar bone and scapula. Comparison: Vertebrate # Columba: 1. The pelvic girdle (hip girdle) is formed by a single bone, the hip bone or coxal bone (coxal = "hip"), which serves as the attachment point for each lower limb. The pectoral girdle has two equal halves which are known as 'ossa innominata'. The available data therefore support recent hypotheses that the anatomical similarities between the fore- and hindlimbs arose during the fin-to-limb transition through the derived co-option of similar developmental mechanisms, while the phylogenetically older pectoral and pelvic girdles have remained more distinct since their evolutionary origin. The most unique character of plesiosaurs is the highly derived locomotory system. 2. When the two hip bones are combined with the sacrum and coccyx of the axial skeleton, they are referred to as the pelvis.The right and left hip bones also converge anteriorly to attach to each other at the pubic symphysis (Figure 8.3.1).

The development of the tetrapod pectoral and pelvic girdles is intimately linked to the proximal segments of the fore‐ and hindlimbs. It is composed of two bones namely clavicle or collar bone and scapula. Pelvic girdle consists of innominate which are similar bones. The ability to bear weight is more important in the pelvic girdle than the pectoral girdle. This gives a trade off for security, rigidity with less flexibility due to its weight bearing role of full body weight. The development of the tetrapod pectoral and pelvic girdles is intimately linked to the proximal segments of the fore‐ and hindlimbs. 234 238) The pelvic girdle is formed by the paired os coxae (coxal bones). The pectoral girdle is a component of the appendicular skeleton, which is responsible for supporting the upper limbs of the body. What is the difference between the pelvic girdle and pectoral girdle? Note: The pectoral girdle stabilizes the upper limbs on the thorax and allows a range of mobility at the shoulder. The genetic networks controlling the formation of the pelvis and scapula also share similarities and differences, with a number of genes shaping only one or the other, while other gene products such as PBX transcription factors act as hierarchical developmental regulators of both girdle structures. 4. Bothe the halves are identical and the clavicles of the two sides fuse at their ventral ends to form the furcula. The pelvic girdle (hip girdle) is formed by a single bone, the hip bone or coxal bone (coxal = "hip"), which serves as the attachment point for each lower limb. Now the skeleton system and the presence of various bones may differ from species to species in the case of reptiles. pelvic: relatively large. 2. 3, Table 1).

It is surrounded by muscles on both its anterior (deep) and posterior (superficial) sides, and thus does not articulate with the ribs of the thoracic cage. 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.. We investigate the degree to which a common history, developmental program, and gene network are shared between the girdles relative to the rest of the appendicular skeleton. Scapula and clavicle are not further divided into any type of bone in Pectoral Girdle. Together with the sacrum and coccyx of the axial skeleton, this group of bones forms the bony pelvis. 2. 1.
