Skeletal System (rev. 2021)

Front

What is the function of Articular Cartilage?

Back

Articular Cartilage is a shock-absorbing tissue that lines the ends of bones at synovial joints, reducing friction and allowing smooth movement.

Front

What are Bursae?

Back

Bursae are small pockets of synovial fluid found in some articulations that help reduce friction between moving parts.

Front

What is the role of Ligaments in the skeletal system?

Back

Ligaments connect bone to bone, providing stability and support to joints.

Front

What are Osteoblasts?

Back

Osteoblasts are bone-forming cells responsible for synthesizing and mineralizing bone during growth and healing.

Front

What do Osteocytes do?

Back

Osteocytes are mature bone cells that maintain bone tissue and communicate with other bone cells to regulate bone remodeling.

Front

What is the function of Osteoclasts?

Back

Osteoclasts are cells that break down bone tissue, playing a crucial role in bone resorption and remodeling.

Front

Define Synovial Fluid.

Back

Synovial fluid is a viscous fluid found in synovial joints that lubricates the joint and nourishes the cartilage.

Front

What is the Medullary Cavity?

Back

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

Front

What is the difference between the Axial and Appendicular skeleton?

Back

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

Front

What are Epiphyseal Plates?

Back

Epiphyseal Plates, or growth plates, are areas of growing tissue near the ends of long bones that allow for lengthwise growth.
