The pectoral girdles are to the upper limbs as the pelvic girdle is to the lower limbs; the girdles are the part of the appendicular skeleton that anchor the appendages to the axial skeleton. In humans, the only true anatomical joints between the shoulder girdle and the axial skeleton are the sternoclavicular joints on each side.
There are 126 bones in the human appendicular skeleton, includes the skeletal elements within the shoulder and pelvic girdles, upper and lower limbs, and hands and feet. [1] These bones have shared ancestry (are homologous ) to those in the forelimbs and hindlimbs of all other tetrapods , which are in turn homologous to the pectoral and pelvic ...
It refers to the fully webbed, swimming appendages of aquatic vertebrates that are not fish. In animals with two flippers, such as whales, the flipper refers solely to the forelimbs. In animals with four flippers, such as pinnipeds and sea turtles, one may distinguish fore-and hind-flippers, or pectoral flippers and pelvic flippers. [2] [3]

The epiploic appendices (or appendices epiploicae, or epiploic appendages, or appendix epiploica, or omental appendices) are small pouches of the peritoneum filled with fat and situated along the colon, but are absent in the rectum. They are chiefly appended to the transverse and sigmoid parts of the colon, however, their function is unknown.
The pectoral fascia is a thin layer of tissue over the pectoralis major, extending toward the latissimus dorsi muscle on the back. Along with the pectoralis major and pectoralis minor, the subclavius muscle forms the axilla or armpit. The subclavius moves the shoulder downward and forward. Serratus anterior is another muscle on the front of the ...
