Bone Cells and Their Functions

Front

What are canaliculi?

Back

Tiny channels that connect lacunae in bone tissue, allowing for communication and nutrient exchange between osteocytes.

Front

What type of tissue is replaced during intramembranous ossification?

Back

Fibrous connective tissue.

Front

What is osteoporosis?

Back

A condition where excessive bone resorption outpaces bone formation, leading to weakened bones.

Front

Which bones are most affected by osteoporosis?

Back

Vertebrae and hips.

Front

What structure contains red bone marrow in adults?

Back

Epiphysis of long bones.

Front

What are osteocytes?

Back

Mature bone cells that maintain bone tissue and communicate through canaliculi.

Front

What is the role of osteoblasts?

Back

Bone-forming cells that synthesize and secrete the bone matrix.

Front

What is the function of osteoclasts?

Back

Cells that break down bone tissue, playing a crucial role in bone remodeling.

Front

What is the medullary cavity?

Back

The central cavity of bone shafts where red and yellow bone marrow is stored.

Front

What is the periosteum?

Back

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