Final answer:
If a person is right-handed, their right-side skeleton is typically slightly larger than their left side, due to the increased use and strength of those muscles and bones.
Step-by-step explanation:
If a person were right-handed, then his or her skeleton on the right side would be slightly larger than the skeleton on the left side. This phenomenon can be attributed to the principles of bone remodeling and muscular development which are influenced by the dominant use of one side over the other. For example, a right-handed pitcher will typically have thicker bones in his right arm compared to his left, due to the repetitive and intensive use of that arm. Similarly, handedness is reflected in cognitive development and has been studied in the evolution of the human species, as seen in the tool use and brain lateralization of Homo habilis. The anatomical dispositions followed by various bones and muscles adhere to the standard body "map," or anatomical position, to avoid confusion when describing body parts. Furthermore, while the external body appears symmetric, the internal organs, such as the heart and liver, display asymmetry, which is an essential component of biological development.
