Skeletal System Review

Front

What is the periosteum?

Back

The periosteum is a dense layer of vascular connective tissue enveloping the bones except at the surfaces of the joints. It serves as a protective layer and provides a surface for muscle attachment.

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. It plays a crucial role in the production of blood cells.

Front

What is yellow marrow?

Back

Yellow marrow is a type of bone marrow that primarily stores fat and is found in the medullary cavity of long bones. It can convert to red marrow if the body needs more blood cells.

Front

What is compact bone?

Back

Compact bone is the dense, hard layer of bone tissue that provides strength and structure. It forms the outer layer of bones and is essential for weight-bearing.

Front

What is the proximal epiphysis?

Back

The proximal epiphysis is the end part of a long bone that is closest to the body's trunk. It is involved in joint formation and contains spongy bone.

Front

What is the diaphysis?

Back

The diaphysis is the long, tubular shaft of a long bone, which provides leverage and support. It is composed mainly of compact bone.

Front

What is the distal epiphysis?

Back

The distal epiphysis is the end part of a long bone that is farthest from the body's trunk. It also plays a role in joint formation.

Front

What is the epiphyseal line?

Back

The epiphyseal line is a remnant of the growth plate (epiphyseal plate) in long bones, indicating where bone growth occurred during development.

Front

What type of bone is the scapula?

Back

The scapula is classified as a flat bone, which provides protection for the underlying structures and serves as an attachment point for muscles.

Front

What type of bone is the femur?

Back

The femur is classified as a long bone, which is characterized by its length and is primarily responsible for supporting weight and facilitating movement.
