Kinesiology TEST T/F
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
F
Typical bony features include tendons, epiphysis, and articular cartilage
F
the scapula is an example of an irregular bone
F
Diarthrodial joints are also known as synovial joints
T
Longitudinal bone growth continues as long as epiphyseal planes are open
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
T
Collagen in bone provides flexibility and strength to resist tension
T
Diagonal abduction is movement by a limb through a diagonal plane away from midline of body
