Exam 8: A: Skeletal Tissues

Most of the matrix in bone is composed of inorganic rather than organic material.

Calcitonin is released when the blood calcium levels are too high.

Canaliculi are small openings in the lamella where bone cells are found.

Osteoporosis occurs more often in elderly women than in males.

The fracture hematoma is the last stage in the healing of a bone.

During childhood and adolescence,ossification and bone resorption occur at equal rates.

Bone tissue is also called osseous tissue.

When cancellous bone is put under mechanical stress,it responds by remodeling its trabecula in a different direction and by increasing their diameter.

Parathyroid hormone affects not only bone cells,but also cells of the kidney.

Interstitial growth of cartilage most often occurs during adulthood.

Callus tissue binds the broken ends of a fractured bone.

Both growth hormone and the neurotransmitter serotonin can stimulate bone growth.

In an infant's or child's body,virtually all of the bones contain yellow marrow.

The inorganic salts that make up the bone matrix are equally divided between hydroxyapatite and calcium carbonate.

Because bone building and bone resorption must be balanced,there are usually an equal number of osteoblasts and osteoclasts in a bone.

Osteoclasts are large,multinucleate cells that erode bone minerals.

Both membrane and endochondral bone grow by interior expansion.

The endosteum usually surrounds yellow marrow in an adult.

Because each bone has a specific function,it is made of either all compact or all spongy bone.

The term woven bone is used to describe new bone.
