Appendicular Skeleton Flashcards
Total of 126 bones which comprises the bones of the
upper and lower limbs, as well as the pectoral and
pelvic girdles
Appendicular skeleton
attach the limbs to the axial skeleton.
Pectoral and pelvic girdles
a place where two bones come together.
Joint
Functional classification of joints
Synanthrosis - non movable
Ampriarthrosis - slight movable
Diarthrosis - freely movable
Structural classification of joints
Fibrous
Cartilaginous
Synovial
Consist of two bones that are unified by
fibrous tissue and that exhibit little to no
movement.
Fibrous joints
Joint held together with very short, interconnecting fibers, and bone edges interlock. Found only in the skull.
Suture
Joint held tpgether by a ligament. Fibrous tissues can vary in length but is longer than in sutures.

Syndesmosis
Peg in socket fibrous joint.
Gomphosis
Holds tooth in socket
Peridontal ligament
Unite two bones by means of cartilage
and permits slight movement.
Cartilaginous joints
Bones united by hyaline cartilage
Synchondroses
Bones united by fibrocartilage
Symphyses
Freely movable joints that contain
synovial fluid in a cavity surrounding the
ends of articulating bones.
Synovial joints
the articular surface of the joint is
covered by a thin layer of
Articular cartilage
the joint cavity of synovial joints is filled with
lines the joint cavity everywhere except the
articular cartilage.
Synovial membrane
The synovial membrane may extend as a pocket or sac called
Bursa
shoulder girdle
Perctoral girdle
Pectoral girdle consist of 4 bones:
2 Scapula
2 Clavicle
attach the upper limb to the body and allows free movement of the upper limb
