Which area of the body contains flat bones?

The area of the body that contains flat bones includes the skull, pelvis, and ribs. Flat bones are characterized by their thin, flattened shape and are primarily involved in protecting internal organs and providing a surface for muscle attachment.

The skull houses and protects the brain, the ribs form a protective cage around the thoracic organs, and the pelvis supports the weight of the upper body when sitting and standing while providing attachment points for muscles and protection for the reproductive organs. In contrast, the upper limbs, lower back, spine, forearm, and thigh primarily consist of long bones and irregular bones, which play different structural roles in the body. Long bones, for instance, are crucial for movement and support while irregular bones serve varied functions, such as those in the vertebral column. This anatomical differentiation is key to understanding bone types and their specific roles in the human body.
