Give two reasons why rib is a poor representation of a structure in the human body?

1. Ribs are not a single structure, but rather a series of individual bones that are connected to the spine. This makes it difficult to study and understand the rib as a whole structure.

2. Ribs are relatively small and thin compared to other bones in the body, such as the femur or the skull. This makes them less visually striking and less likely to be used as a representation of the human body in anatomical diagrams or models.

1. Ribs are not weight-bearing: Unlike bones such as the femur or tibia, ribs do not support the weight of the body. They are primarily involved in protecting the thoracic cavity and facilitating respiration.
2. Ribs are not rigid: Ribs are curved and flexible, allowing them to expand and contract during breathing. This flexibility limits their ability to provide structural support or stability to the body.
