Human Skeleton •In embryos, the skeleton is primarily hyaline cartilage •During development, much of this cartilage is replaced by bone – called ossification •Cartilage remains in isolated areas •Bridge of the nose •Parts of ribs •Joints © 2012 Pearson Education, Inc.
24.
Bone Growth (Ossification)
•Epiphyseal plates allow for lengthwise growth of long bones during childhood •New cartilage is continuously formed •Older cartilage becomes ossified •Cartilage is broken down •Enclosed cartilage is digested away, opening up a medullary cavity •Bone replaces cartilage through the action of osteoblasts © 2012 Pearson Education, Inc.
25.
Bone Growth (Ossification)
•Bones are remodeled and lengthened until growth stops •Bones are remodeled in response to two factors •Blood calcium levels •Pull of gravity and muscles on the skeleton •Bones grow in width (called appositional growth) © 2012 Pearson Education, Inc.

Types of Bone
Cells •Osteocytes—mature bone cells •Osteoblasts—bone-forming cells •Osteoclasts—giant bone-destroying cells •Break down bone matrix for remodeling and release of calcium in response to parathyroid hormone •Bone remodeling is performed by both osteoblasts and osteoclasts © 2012 Pearson Education, Inc.

Bone Fractures
•Fracture—break in a bone •Types of bone fractures •Closed (simple) fracture—break that does not penetrate the skin •Open (compound) fracture—broken bone penetrates through the skin •Bone fractures are treated by reduction and immobilization © 2012 Pearson Education, Inc.
29.
Common Types of
Fractures http://www.youtube.com/w atch?v=c5Q5GPwAS4k •Comminuted—bone breaks into many fragments Setting a bone: http://www.youtube.com/watch?v=nQVih •Compression—bone is crushed uOUQkU&feature=related •Depressed—broken bone portion is pressed inward •Impacted—broken bone ends are forced into each other •Spiral—ragged break occurs when excessive twisting forces are applied to a bone •Greenstick—bone breaks incompletely © 2012 Pearson Education, Inc.
