Vertebrae

The vertebrae are irregular bones.

The rib is a flat bone.

Humerus

The humerus is a long bone.

• Humerus = long bone

• Rib = flat bone

• Patella = sesamoid bone

• Vertebrae = irregular bone

• Carpals = short bones

•  in the human body are classified into five main types based on their shape and function:

  1. Long Bones

     • Longer than they are wide.

     • Provide strength, structure, and mobility.

     • Example: humerus, femur, tibia, radius.

  2. Short Bones

     • About equal in length, width, and thickness (cube-like).

     • Provide stability and support with little movement.

     • Example: carpals (wrist bones), tarsals (ankle bones).

  3. Flat Bones

     • Thin, flattened, often curved.

     • Provide protection and large surfaces for muscle attachment.

     • Example: ribs, sternum, scapula, skull bones.

  4. Irregular Bones

     • Complex shapes that don’t fit into the other categories.

     • Provide protection and support in special ways.

     • Example: vertebrae, hip bones (pelvis), some skull bones.

  5. Sesamoid Bones

     • Small, round bones embedded within tendons.

     • Reduce friction, modify pressure, and sometimes change the direction of muscle pull.

     • Example: patella (kneecap), and small sesamoid bones in the hands and feet.
