Unit 4 Skeletal System Test

Front

What are the main functions of the skeletal system?

Back

The skeletal system provides support, protects internal organs, facilitates movement, produces blood cells, and stores minerals such as calcium.

Front

What is the role of synovial fluid in joints?

Back

Synovial fluid reduces friction between the articular cartilage of synovial joints, allowing for smooth movement.

Front

What is the lacrimal bone?

Back

The lacrimal bone is a small bone located in the eye socket that helps form the structure of the orbit.

Front

What type of joint allows limited movement?

Back

Cartilaginous joints allow limited movement, such as the joints between the vertebrae.

Front

What is the zygomatic bone?

Back

The zygomatic bone, also known as the cheekbone, is located on the side of the face and contributes to the structure of the orbit.

Front

What is the function of the temporal bone?

Back

The temporal bone houses structures of the inner ear and is involved in the formation of the skull.

Front

What is the difference between fibrous and synovial joints?

Back

Fibrous joints are immovable and connected by dense connective tissue, while synovial joints are movable and contain a fluid-filled joint cavity.

Front

What is the significance of red bone marrow?

Back

Red bone marrow is responsible for the production of red blood cells, white blood cells, and platelets.

Front

What is the role of calcium in the skeletal system?

Back

Calcium is essential for maintaining bone density and strength, and it plays a critical role in muscle contraction and nerve function.

Front

What are the major components of the axial skeleton?

Back

The axial skeleton includes the skull, vertebral column, and rib cage.
