Abduction is an example of movement in a coronal plane about an anteroposterior axis.

True

Bone size and shape are influence by both the direction and magnitude of forces that are habitually applied to them.

True

Bones continue to grow longitudinally as long as the epiphyseal plates are open.

True

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

True

Both the size and the shape of bones can limit or allow movements.

True

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

Flexion or extension can occur in combination with abduction, adduction, or rotation.

True

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

True

The hyaline cartilage is quite resilient because it is slightly compressible and elastic.

True

Typical bony features include diaphysis, epiphysis, and articular cartilage.

True

About 50 to 60 percent of the volume of cortical bone is porous.

False

Aging causes progressive gain of collagen and increases bone brittleness.

False

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

False

During the process of bone remodeling, osteoblasts reabsorb existing bone and osteoclasts from new bone.

False

Epiphyseal plates generally close by age 14, but some may be present until age 18.

False

Ligaments and connective tissue provide dynamic stability to joints when actively contracting.

False

One of the functions of articular cartilage is to separate the diaphysis and epiphysis.

False

The endosteum is located at the ends of long bones.

False

The scapula is an example of an irregular bone.

False

There are approximately 552 skeletal muscles in the human body.
