Abstract
Bone tissue is not considered an integral part of the fascial system as per the current definition of fascia. Bodily fasciae derive from the mesoderm, while the fasciae associated with the cranial-cervical area derive from the ectoderm. Bone tissue or specialized connective tissue follows the same development process, but with a greater admixture between the two embryological sheets. Bone tissue is the largest organ capable of producing autocrine and paracrine substances, influencing its own metabolism and that of other organs. This article reviews the functions of bone, the anatomy that determines its shape, and its relationships within an organism. The objective of the article is to provide a scientific rationale for incorporating bone tissue within the definition of fascia, using the most up-to-date scientific knowledge.
