Front

What is a ball and socket joint?

Back

A type of synovial joint that allows for rotational movement in multiple directions, exemplified by the hip and shoulder joints.

Front

What is the diaphysis of a long bone?

Back

The diaphysis is the long, tubular shaft of a long bone, primarily composed of compact bone.

Front

What are synovial joints?

Back

Joints that are characterized by a fluid-filled joint cavity, allowing for a wide range of motion; examples include hinge, ball and socket, and saddle joints.

Front

What is the epiphyseal plate?

Back

A layer of cartilage located at the ends of long bones where bone growth occurs during childhood and adolescence.

Front

What is the periosteum?

Back

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

Front

What are the types of joints in the skeletal system?

Back

The main types include synovial, fibrous, and cartilaginous joints.

Front

What is the function of spongy bone?

Back

Spongy bone provides structural support and flexibility, and it houses bone marrow.

Front

What is the medullary cavity?

Back

The central cavity of long bones that contains bone marrow, which produces blood cells.

Front

What is the difference between compact bone and spongy bone?

Back

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

Front

What are cartilaginous joints?

Back

Joints where the bones are connected by cartilage, allowing for limited movement; examples include the joints between vertebrae.
