Bone Anatomy

Lamellae

• Thin layers of bone matrix in compact bone.

• Thick layers of cartilage found in joints.

• Cells responsible for bone resorption.

• Fluid-filled spaces within bone tissue.

Spongy Bone

• bone that contains trabeculae and red marrow

• bone that is dense and compact

• bone that is primarily made of collagen

• bone that is found only in the skull

What is an Osteocyte?

• A type of white blood cell involved in immune response.

• Mature bone cell embedded in the bone matrix.

• A precursor cell that forms cartilage.

• A cell that breaks down bone tissue.

Osteon (Haversian System)

• Structural unit of compact bone.

• A type of muscle tissue.

• A component of the nervous system.

• A type of cartilage.

Diaphysis

• Shaft of a long bone

• End of a long bone

• Outer layer of a bone

• Cartilage covering the bone surface

Articular Cartilage

• Hyaline cartilage covers the ends of bones at joints.

• Elastic cartilage provides flexibility and support.

• Fibrocartilage is found in intervertebral discs.

• Bone tissue is responsible for blood cell production.

Red Bone Marrow

• Located in the spongy bone of certain bones.

• Responsible for the production of hormones.

• Found only in the long bones of adults.

• Involved in the storage of fat.

Osteoclast

• Large cell that breaks down bone tissue.

• Small cell that builds bone tissue.

• Cell that stores fat in the bone marrow.

• Cell that produces red blood cells.

Trabeculae

• Network of bony struts in spongy bone.

• A type of muscle tissue found in the heart.

• A layer of connective tissue surrounding bones.

• A type of cartilage found in joints.

Endosteum

• Thin, vascular membrane lining the inner surface of the medullary cavity.

• A type of bone cell responsible for bone resorption.

• The outer layer of bone that provides structural support.

• A type of cartilage found in joints.
