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
