The mesoderm provides the form and contributes to the function of the apparatus, through smooth muscles, visceral striated muscles and other cells (mesenchymal cells, intestinal subepithelial myofibroblast). The gastrointestinal tract forms from the endoderm (which gives rise to the epithelium) and the mesoderm. ![]() The lateral plate mesoderm splits into parietal (somatic) and visceral (splanchnic) layers: the parietal layer forms the lateral body wall folds and the skeletal striated muscle, and the visceral mesoderm forms the walls of the gut tube. The gonads, kidney and reproductive tract are derived from intermediate mesoderm. Paraxial mesoderm gives rise to somites, blocks of tissue running along both sides of the neural tube, which form muscle and the tissues of the back, the thorax and part of the neck, including connective tissue and the dermis. The mesodermal cells are organized into three sheets: paraxial mesoderm intermediate mesoderm lateral plate mesoderm. Gastrointestinal tract mesodermal development This text continues with another article about heart embryological development, as well as muscles and collagen, concluding a scientific path to improve the definition of fascia. Our committee of the Foundation of Osteopathic Research and Clinical Endorsement (FORCE), for the definition and nomenclature of the fascial tissue, discusses in this first article the inclusion of certain other viscera in the fascial field. The article highlights the presence of smooth and visceral striated muscle cells in different organs, underlying the mesodermal origin. They are some of the viscera present in the mediastinum, in the abdomen and in the pelvic floor. Tissues consist of smooth muscle and non-voluntary striated musculature, originated from the mesoderm and with the properties described, they have never been properly considered. The fascia has the property of maintaining the shape and function of its anatomical district, but it also can adapt to mechanical-metabolic stimuli, feeding the tissue. Fascia is the epidermis, the dermis, the adipose tissue, the skeletal muscle (with its connective tissue) and its tendons and ligaments, the circulatory and lymphatic system (vessels blood and lymph), the meningeal tissue and nervous tissue, the joint capsule and bone tissue. ” According to current scientific standards, the fascia is a connective tissue derived from two separate germ layers, the mesoderm and the ectoderm (cervical tract and skull). ” This definition expands the definition of the Fascia Nomenclature Committee (2014), about what the fascia is and what it should include: “The fascial system includes adipose tissue, adventitia, neurovascular sheaths, aponeuroses, deep and superficial fasciae, dermis, epineurium, joint capsules, ligaments, membranes, meninges, myofascial expansions, periosteum, retinacula, septa, tendons (including endotendon/peritendon/epitendon/paratendon), visceral fasciae, and all the intramuscular and intermuscular connective tissues, including endomysium/perimysium/epimysium. ![]() ![]() These afferent/efferent impulses come from the fascia and the tissues that are not considered as part of the fascia in a bi-univocal mode. The continuum constantly transmits and receives mechano-metabolic information that can influence the shape and function of the entire body. The fascial continuum is the result of the evolution of the perfect synergy among different tissues, liquids and solids, capable of supporting, dividing, penetrating, feeding and connecting all the districts of the body, from the epidermis to the bone, involving all the functions and organic structures. Our Foundation of Osteopathic Research and Clinical Endorsement (FORCE) in our previous work defined the fascia as follows: “The fascia is any tissue that contains features capable of responding to mechanical stimuli.
