Gross Anatomy of a Long Bone Diagram | Quizlet

Distal Epiphysis

Composed of mostly spongy bone filled with connective tissue and bone marrow; covered in articular cartilage, enabling bones to move at the joints without grinding.

Diaphysis

- The shaft or central part of a long bone; composed of compact bone.

Proximal Epiphysis

End of the bone closest to the body; composed mostly of spongy tissue.

Spongy Bone

Highly vascularized and contains red bone marrow, usually located at the ends of the long bones (the epiphyses), with the harder compact bone surrounding it.

Articular Cartilage

The smooth, white tissue that covers the ends of bones where they come together to form joints.

Epiphyseal Line

Thin line of bony tissue spanning the epiphysis that looks a bit different from the rest of the bone, this is a remnant of the epiphyseal plate seen in young, growing bone.

Periosteum

A dense layer of vascular connective tissue enveloping the bones except at the surfaces of the joints.

Compact Bone

A denser material used to create much of the hard structure of the skeleton; looks smooth and homogeneous.

Medullary Cavity

The central cavity of bone shafts where red bone marrow and/or yellow bone marrow (adipose tissue) is stored.
