Skeletal System Flashcard

Front

What is ossification?

Back

The process of incorporating calcium and minerals into cartilage to form bone.

Front

What is the role of osteoclasts in bone growth?

Back

They secrete acid to enlarge the medullary cavity.

Front

What is the primary function of osteocytes in bone tissue?

Back

Maintenance of bone tissue.

Front

Which hormone is secreted by the thyroid gland to help regulate calcium levels?

Back

Calcitonin.

Front

Where does secondary ossification take place in bone development?

Back

In the epiphyseal plates.

Front

What are osteoblasts?

Back

Cells responsible for bone formation.

Front

What is the medullary cavity?

Back

The central cavity of bone where marrow is stored.

Front

What is the function of the periosteum?

Back

A dense layer of vascular connective tissue enveloping the bones except at the surfaces of the joints.

Front

What is the difference between compact bone and spongy bone?

Back

Compact bone is dense and forms the outer layer of bone, while spongy bone is lighter and found inside bones, containing red marrow.

Front

What is the role of parathyroid hormone in bone health?

Back

It regulates calcium levels in the blood by increasing the release of calcium from bones.
