The pelvis is classified as a flat bone. It consists of several bones that fuse together, including the ilium, ischium, and pubis. Flat bones, such as the pelvis, have a thin, flattened shape and serve various functions, including providing surface area for muscle attachment, protecting vital organs, and facilitating movement.
The pelvis plays a crucial role in the skeletal system, acting as a support structure for the weight of the upper body and forming a protective cavity for organs in the lower abdomen. Additionally, the shape and structure of the pelvis are important for bipedal locomotion as they provide balance and stability when walking or running. Its unique anatomy also allows for the attachment of the lower limbs, enabling a wide range of movements.
