Exam 8: A: Skeletal Tissues

The periosteum is a dense,white,fibrous membrane that covers bone except at joint surfaces.

Parathyroid hormone stimulates the activity of osteoclasts in the bone.

The type of cartilage growth most prevalent in childhood and early adolescence is interstitial or endogenous growth.

Lamellae and lacunae are interchangeable terms.

Osteoblasts themselves are able to monitor extracellular calcium levels.

Due to the continuous stress on the bone,athletes and dancers tend to have less dense bones than do more sedentary people.

The layer of cancellous bone between two layers of compact bone is called diploë.

Weight-bearing exercises will tend to increase the likelihood of osteoporosis in the elderly.

The homeostasis of blood calcium is maintained by its moving into and out of bone tissue.

The strength of bone is increased by the arrangement of trabeculae.

Haversian systems are found only in compact bone.

Bone tissue consists mostly of cells dispersed in a limited amount of matrix.

Chondroitin sulfate is an important compound in ground substance.

The thyroid gland produces the parathyroid hormone,which is the major regulator of blood calcium homeostasis.

A major difference between bone tissue and cartilage is the makeup of the matrix.

Articular cartilage can be defined as a layer of elastic cartilage that covers the joint surface.

After birth,the amount of cartilage in the body increases.

Osteoblasts secrete the inorganic salts that make up the structure of bone.

Throughout life,ossification and resorption continue to occur concurrently.

Both cartilage and bone contain living cells and are vascular tissues.
