H1 A&P Intro Microanatomy of Bone BFHS

Front

What is a lamella?

Back

A lamella is a thin layer of bone tissue that forms part of the structure of compact bone.

Front

What are trabeculae?

Back

Trabeculae are needlelike structures in spongy bone that are arranged along stress lines to provide strength.

Front

What is the function of the epiphyseal plate?

Back

The epiphyseal plate is responsible for the lengthwise growth of long bones during development.

Front

What are osteoclasts?

Back

Osteoclasts are large, multi-nucleated cells that are responsible for the resorption of bone tissue.

Front

What is yellow marrow?

Back

Yellow marrow is a type of bone marrow that primarily functions in fat storage.

Front

What is the role of osteoblasts?

Back

Osteoblasts are cells that are responsible for the formation of new bone tissue.

Front

What are osteocytes?

Back

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

Front

What is the periosteum?

Back

The periosteum is a dense layer of vascular connective tissue that envelops the bones except at the surfaces of the joints.

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 are canaliculi?

Back

Canaliculi are small channels in bone that connect lacunae and allow for communication and nutrient exchange between osteocytes.
