Bone Shapes: Flat, Long, Short, and Irregular

Four Core Shapes: Every bone in your body fits into one of four types — long, short, flat, or irregular.
Long Bones Lead the Way: Femurs, humerus, and tibias are long bones built for support, strength, and movement.
Short and Sturdy: Carpals (wrist) and tarsals (ankle) are short bones that provide stability and absorb impact.
Flat and Protective: Skull, ribs, and shoulder blades are flat bones designed to shield organs and anchor muscles.
Irregular Originals: Vertebrae and facial bones defy easy classification — uniquely shaped for specialized jobs.
Design with Purpose: Each bone’s shape matches its function — from leverage to protection to fine movement.
Long Bones Grow Taller: Growth plates in long bones drive height increases during childhood and puberty.
Flat Bone Factories: Flat bones contain red bone marrow, producing billions of blood cells daily.
Irregular Strength: The spine’s oddly shaped vertebrae protect nerves while allowing flexibility and support.
Shape Defines Strength: Together, these four bone types create the perfect balance of mobility, stability, and protection in your skeleton.
