Appendicular skeleton
Bones of the limbs
Functions of skeletal system
Support, protection, movement, storage, blood cell formation
4 bone shape classification
Long bones, short bones, flat bones, irregular bones
Diaphysis
Shaft, makes up most of the bones length, composed of compact bone
Epiphysis
The ends of the long bone
Epiphyseal plate
Growth plate found in young, growing bones
Articular cartilage
Covers the surface of the epiphysis
Periosteum
Covers the diaphysis with a connective tissue
Red bone marrow
For adults is found in flat bones and the epiphysis of some long bones
Yellow bone marrow
Located inside diaphysis
Storage place for adipose tissue
Firms red blood cells for infants
Ligaments
Join bone to bone
Ball and socket
Action, free movement in all directions, shoulder and hip
Hinge
Action, bending only in one direction. Elbows, knees, and between phalanges
Pivot
Action, rotating and swiveling. Neck bones, Lowe arm bones.
Plane
Action, limited movement sideways and up and down, between carpals and between tarsal bones
Synovial fluid
Fluid secreted by synovial membrane which lubricates joint surfaces and nourishes articular cartilage
Bursa
Lubricating sacs located around friction areas in joints
Synovial membrane
Membrane surrounding joints providing a smooth surface and secrete lubricating fluid creating a fluid filled cushion between moving parts
