Human A and P Bone Anatomy 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.

Front

What is the proximal epiphysis?

Back

The proximal epiphysis is the end part of a long bone, opposite the distal epiphysis, which is involved in the formation of joints.

Front

What are flat bones?

Back

Flat bones are thin and flattened bones that provide protection and a surface for muscle attachment, such as the skull and ribs.

Front

What are lacunae in bone anatomy?

Back

Lacunae are small cavities in bone tissue that contain osteocytes, which are mature bone cells.

Front

Where is spongy bone primarily found?

Back

Spongy bone is primarily found in the epiphyses of long bones, providing structural support and flexibility.

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 diaphysis?

Back

The diaphysis is the long, tubular shaft of a long bone, providing leverage and support.

Front

What is the function of osteocytes?

Back

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

Front

What is the role of the periosteum in bone health?

Back

The periosteum plays a crucial role in bone growth, repair, and nutrition by providing a surface for muscle attachment and containing blood vessels.

Front

What are irregular bones?

Back

Irregular bones are bones that do not fit into the other categories (long, short, flat) due to their complex shapes, such as vertebrae.
