Flexion/extension is an example of movement in a coronal plane about an anteroposterior axis

F

Ligaments through their bone to bone connections provide dynamic stability to diarthrodial joints

F

One of the functions of articular cartilage is to seperate the diaphysis to the epiphysis

F

Osteoclasts are specialized cells that form and resorb new bone

F

The medullary canal is located at the ends of long bones

F

The shape of bones does not limit movement

F

There are approximately 552 muscles in the human body

T

Most outer bone is composed of cortical bone with cancellous bone underneath

T

Of all the movements possible in the joints of the body, flexion/extension is the most commonly occurring

T

Aging induces a progressive increase of collagen in bone that results in an increase in brittleness

F

Cancellous bone is stiffer and therefore can withstand greater stress but less strain than cortical bone

F

Cortical bone has a low degree of porosity which consists of approximately 5-30% mineralized bone

F

During the process of bone remodeling osteoblasts resorb existing bone and osteoclasts form new bone

F

Epiphyseclal plates generally close by age 18 but some may be present until age 27

F

Bone size and shape are influenced by both the direction and magnitude of applied forces

T

Bones reshape themselves based upon the stresses that are placed upon them

T

Both the size and shape of bones can limit or allow movement
