Mesotendon, Mesotendon

Mesotenendon (fr. Méso-tendon - “intermediate tendon”), also mesentery of the tendon, two-story tendon), is the space between the atypical zone of the inner layer of the vaginal floor of the muscular aponeurotic septum and the epiphyseal bone.

Its anatomical and histological structure resembles the connective tissue of a tendon. Partially represented by both ventral and dorsal tendon branches in the wrist area. In most cases it does not reach larger joints and has no functional significance. As a rule, it lacks perichondrium or has very little thickness. The structure and functions of mesotenedin are variable, which is reflected in a number of terminological interpretations and definitions.

- The synovial layer of mesotendin skin is rich in elastic fibers and elastic glands, so the skin here is stronger and more elastic than the skin of the legs. The skin has many sebaceous and sweat glands. - In its deep layers there are blood vessels. Passing along the tendon, they branch and are located next to the tendon fibers, providing them with nutrition. To prevent scars from forming on the skin, after surgery, sutures are sometimes placed over the tendon - catgut ligatures. The mesotenedia are innervated by peripheral nerve bundles present in the rotator cuff of the shoulder joint. Through them, the neuroanatomical branching of the suprascapular, axillary and intercostal nerves occurs, providing innervation to the subcutaneous tissue of the upper arm of the forearm, as well as the distal portions of a number of muscles, including the biceps brachii muscle. Mesoteneoinnervation occurs after surgery, allowing the viability of the rotator cuff muscles to be assessed during biopsy to determine the presence of malignancy.

Introduction

The mesotendon and mesentery of the tendon are two layers that form the synovial sheath of the tendon. The tendon, together with the mesotendon and mesentery, forms a complex system that allows the tendon to move smoothly and steadily. In this article we will look at the structure, functions and importance of these elements for human health.

Structure and composition Both elements consist of a synovial membrane - a special connective tissue that contains many blood vessels and nerves to provide nutrition and innervation to the tendons. The mesotendon consists of the outer and inner layers of the synovial sheath, while the mesentery consists of only the outer layer. Both layers also contain ligament fibers, special tissues that provide strength and stability to the tendon and joint.

Functions and Importance Tendons play an important role in joint movement due to their ability to shorten and lengthen as needed. But for the tendon to work properly, it must have reliable support and protection from external influences. The mesotendron and mesentery of the tendon perform these functions by providing support and control over the movement of the tendon. In addition, both elements are important in balancing the tension and forces generated in muscles and tendons during movement. Thus, these elements help maintain muscle tone and strengthen the joint.

Diseases and Disorders Disorders in the structure or function of the mesotendon and tendon mesenteries can lead to various joint diseases such as tendonitis
