Exam 8: A: Skeletal Tissues

In endochondral ossification,the primary ossification centers are found in the epiphyses and the secondary ossification centers are found in the diaphyses.

Hydroxyapatite consists of highly specialized chemical crystals of calcium and phosphate.

The epiphyses consist mostly of compact bone,usually with yellow marrow in the center.

Transverse canals are located in the center of the osteon.

Calcitonin is a protein hormone produced by the pituitary gland that helps regulate blood calcium levels.

All the lamellae in compact bone are found to be part of the osteon.

The body contains more spongy bone than it does compact bone.

One function of cartilage is to act as a shock-absorbing pad between bones.

In an adult who is anemic or has been exposed to radiation or toxic chemicals,yellow bone marrow can become red bone marrow again.

Sesamoid bones develop in tendons near a joint.

Myeloid tissue is another name for bone marrow.

Another name for compact bone is cancellous bone.

The endosteum is necessary for bone healing and bone remodeling.

There are more than 200 bones in the human body.

The patella or kneecap is the only sesamoid bone ever found in the human body.

Because bone is connective tissue,a fractured bone will never heal and be as strong as before the fracture.

The tensile strength of bone is nearly equal to that of cast iron,but much lighter.

The growth of intramembranous bone begins with the formation of a cluster of osteoblasts called ossification centers.
