Marieb A&P Bone Structure and Function Concepts

Front

What is the primary function of osteocytes in bone remodeling?

Back

Osteocytes respond to and communicate mechanical stimuli to osteoblasts and osteoclasts, facilitating bone remodeling.

Front

What are the two main groups into which bones are divided?

Back

Bones are divided into the axial skeleton and the appendicular skeleton.

Front

List the five major cell types found in bones.

Back

The five major cell types in bones are osteogenic cells, osteoblasts, osteocytes, bone lining cells, and osteoclasts.

Front

What type of bone are vertebrae and coxal bones classified as?

Back

Vertebrae and coxal bones are classified as irregular bones.

Front

What are the two main components of the structure of a long bone?

Back

The two main components of a long bone are the diaphysis and the epiphyses.

Front

Define osteoblasts and their role in bone tissue.

Back

Osteoblasts are bone-forming cells that synthesize and secrete the bone matrix.

Front

What is the role of osteoclasts in bone physiology?

Back

Osteoclasts are responsible for bone resorption, breaking down bone tissue.

Front

Explain the function of osteogenic cells.

Back

Osteogenic cells are stem cells that differentiate into osteoblasts and are involved in bone growth and repair.

Front

What is the significance of bone lining cells?

Back

Bone lining cells are involved in the maintenance and regulation of bone remodeling.

Front

Differentiate between the axial skeleton and the appendicular skeleton.

Back

The axial skeleton includes the skull, vertebral column, and rib cage, while the appendicular skeleton consists of the limbs and girdles.
