Bones that are longer than they are wide (e.g., femur, humerus)

Cube-shaped bones providing stability and support with limited movement (e.g., carpals, tarsals).

Thin, flattened, and usually curved bones that protect internal organs (e.g., skull, ribs).

Bones with complex, unique shapes that do not fit other categories (e.g., vertebrae, hip bones).

The main shaft or central section of a long bone.

The expanded end part of a long bone.

The remnant of the epiphyseal plate (growth plate) in an adult bone.

The narrow portion of a long bone between the epiphysis and the diaphysis.

The central cavity of bone shafts where bone marrow is stored.

Bone marrow high in fat cells, functioning primarily as energy storage.

Dense layer of vascular connective tissue enveloping the bones

Smooth, white tissue covering the ends of bones where they come together to form joints.

Porous, light inner bone tissue containing trabeculae.

Supporting bundles of fibers forming a meshwork in spongy bone.

Specialized tissue producing red blood cells, white blood cells, and platelets.

The fundamental functional unit of compact bone.

Central channel containing blood vessels and nerves in an osteon.

A mature bone cell that maintains bone tissue.

A bone-forming cell that secretes the bone matrix.

A large cell that absorbs and breaks down bone tissue during growth and healing.

Tiny microscopic canals that connect lacunae, allowing nutrients and wastes to pass between osteocytes.

Concentric rings or layers of hard, calcified matrix in bone tissue.

A thin vascular membrane lining the inner cavity and central canals of a bone.

Small cavities in bone matrix that contain individual osteocytes.

Tubular structures (arteries, veins, capillaries) that transport blood throughout the body and bone tissue.

Small branches of arteries that lead into capillaries to deliver oxygenated blood.

Small blood vessels that collect blood from capillaries and drain into veins.
