Appendicular Muscles - fish. Originated as extensions of hypaxials of body wall. Chapter 9. Introduction. Transitions from water to land and from land to air have allowed for a great diversity of forms within the appendicular skeleton.. As with many other designs, form closely follows function.. 1 Appendicular Skeleton: : 4 bones --2 scapula (shoulder blade)2 clavicle (collar bone): 60 bones --2 humerus (upper arm)2 radius (rotating forearm bone) 2 ulna (stationary forearm bone)16 carpals (w Ch. 8.

Pectoral (shoulder) girdle. Clavicles (collar bones). Articulate medially with the manubrium as the only attachment to the axial skeleton. Articulates laterally with the scapula. Serves as a brace for the scapula and stabilizes the shoulder. CHAPTER 7 PART II. The . Appendicular. Skeleton.
