Collar bone Double curved Attaches medially to manubrium of sternum Movement in shoulder girdle. 1) only attaches at one point to axial skeleton 2) Loose attachment of scapula allows it to slide. Figure – Pectoral Girdle: The pectoral girdle consists of the clavicle and the scapula, which serve to attach the upper limb to the sternum of the axial skeleton. The scapula (shoulder blade) lies on the posterior aspect of the shoulder. It articulates with the humerus (arm bone) to form the shoulder joint (the glenohumeral joint).
-large pectoral, small pelvic-broad based fins in early forms-no dermal bone, large scapulocoracoid, connects left and right girdles-pelvic girdle connected by simple rod of cartilage-modern narrow fin base allows fin to rotate/help with maneuvering-3 basal pterygiophores in pectoral fin-2 basal pterygiophores in pelvic fin. The bony structures of the shoulder include the pectoral girdle and one arm bone. These bones have some interesting landmarks, including various bumps and projections. The shoulder and arm bones can be broken or dislocated by traumatic injuries. The pectoral girdle The two bones of the shoulder, the clavicle and the scapula, comprise the pectoral [ ].

In appearance, their bodies were sharklike, with broad, fleshy paired pectoral fins, pelvic fins and an anal fin, as well as a single dorsal fin. In many advanced arthrodires, the tail was naked, but in more primitive forms the tail was covered with scales that didn’t overlap, that were small polygonal plates of bone with an ornamentation of.

Abstract. A brief account and new restorations of the Scottish Middle Old Red Sandstone fish Rhamphodopsis are given, based largely on new material from Edderton, Ross-shire. The Edderton material is of the species Rhamphodopsis threiplandi Watson, previously known only from A chanarras, Caithness.

The pectoral girdle of sibyrhynchids consists of a pair of prominent, elongated and robust scapulocoracoids, a pair of small and thin triangular suprascapular cartilages and an unpaired intercoracoid basal plate (sc, supsc, intc, Fig.

Structural characteristics of the pectoral girdle that adapt it to a wide range of movement include a) heavy bones b) relatively weak joints c) limited range of motion at the shoulder joint d) joints stabilized by ligaments and tendons to the thoracic cage.
