A&P I Long Bone Labeling Flashcards

Study Notes

Long Bone Structures

Articular Cartilage: Smooth tissue covering bone ends, facilitating joint movement and reducing friction.
Spongy Bone: Lightweight, porous bone tissue inside the bone, providing structural support and housing marrow.
Red Marrow: Located in the spongy bone, responsible for producing red blood cells, white blood cells, and platelets.
Endosteum: Thin membrane lining the medullary cavity, involved in bone growth, repair, and remodeling.
Compact Bone: Dense and strong outer layer of bone, providing strength and support while housing the bone's vascular systems.
Medullary Cavity: Central cavity within long bones, containing yellow marrow in adults, which stores fat and energy.
Yellow Marrow: Fatty tissue found within the medullary cavity, serving as an energy reserve.
Periosteum: Tough outer membrane covering the bone, containing blood vessels and nerves, essential for growth and repair.
Epiphyseal Plates: Growth plates located at the ends of long bones, responsible for bone lengthening during development.
Proximal Epiphysis: The end of the bone closest to the body's center, often larger to provide joint stability.
Diaphysis: The long, cylindrical shaft of the bone, responsible for length and structural integrity.
Distal Epiphysis: The far end of the bone from the body's center, connecting with adjacent bones at joints.
