Kinesiology exam 1 TRUE/FALSE
Aging induces a progressive increase in brittleness
FALSE
Cancellous bone is stiffer and therefore can withstand greater stress but less strain than cortical bone
FALSE
Cortical bone has a low degree of porosity which consists of approximately 5-30% mineralized tissue.
FALSE
Ligaments through their bone to bone connections provide dynamic stability to diarthrodial joints
FALSE
One of the functions of the articular cartilage is to separate the diaphysis and epiphysis
FALSE
Osteoclasts are specialized cells that form and resorb new bone
FALSE
The scapula is an example of an irregular bone
FALSE
The shape of bone does not limit movements
FALSE
Bone size and shape are influenced by both the direction and magnitude of applied forces
TRUE
Bones reshape themselves based upon the stresses that are placed upon them
TRUE
Both the size and shape of bones can limit or allow movement.
TRUE
Collagen in bone provides flexibility and strength to resist tension
TRUE
During the process of bone remodeling osteoblasts resorb existing bone and osteoclasts from new bone
FALSE
Epiphyseal plates generally close by the age of 18 but some may be present until age 27
FALSE
Flexion/extension is an example of movement in a coronal plane about an anteroposterior axis
FALSE
There are approximently 552 bones in the human body
FALSE
Typical boney features include tendons, epiphysis, and articular cartilage
FALSE
the medullary canal is located at the end of long bones
FALSE
Diagonal abduction is movement by a limb through a diagonal plane away from the midline of the body
TRUE
Diarthrodial joints are also known as synovial joints
TRUE
Longitudinal bone growth continues as long as epiphyseal plates are open
TRUE
Most outer bone is composed of cortical bone with cancellous bone underneath
TRUE
Of all the movements possible in the joints of the body, flexion/extension is the most commonly occurring
TRUE
