Anatomy of Long Bones

This set of flashcards covers key concepts related to the anatomy of long bones, including their structure, types of bone tissue, and functions.

Epiphyses

The ends of a long bone, typically covered by articular cartilage.

Diaphysis

The shaft or central part of a long bone.

Periosteum

The fibrous membrane that covers the outer surface of a long bone.

Medullary cavity

The hollow area inside the shaft of a long bone, containing bone marrow.

Articular cartilage

The type of cartilage that covers the ends of long bones, providing a smooth surface for joint movement.

Compact bone

Dense bone that forms the outer layer of the bone structure.

Spongy bone

Bone tissue that has a lattice-like structure with trabeculae, found inside the bone.

Canaliculi

Small channels in compact bone that connect osteocytes, allowing for nutrient and waste exchange.

Central (Haversian) canal

The canal that runs through the center of each osteon in compact bone.

Epiphyseal line

Remnant of the growth plate, indicating where bone elongation occurred.
