Myotendinous junction (JMT) is the region that interacts with tendon and muscle tissue. The musculature represents approximately 50% of body weight, and basically consists of a reddish-looking belly resulting from the great vascularization of its cells, called muscle fibers. These fibers have the capacity of contraction, which allows the application of tension to the bones through the tendon enabling joint movement. The function of the JMT is predominantly related to the transfer of the force produced by the muscular tissue through these contractions, to the connective tissue that forms the tendons. These tendons consist of dense connective tissue, formed by fibroblasts and extracellular matrix, which are concentrated in fibrous proteins such as elastin and collagen, the latter representing about 86% to 95% of their wet weight. In addition to this main characteristic, the JMT is also responsible for the storage of some of the elastic energy produced in muscle contractions performed through myofibrils. The main objective of this study is to collect morphological and structural information from the JMT through bibliographic research, to identify specific organizational and interaction characteristics between muscle and tendon, as well as new information about the implications and causes of more common lesions of this structure, is still little studied in relation to others. This survey will be performed through a bibliographic review will occur through queries in databases such as PUBMED, SCIELO, GOOGLE ACADEMMICO, LILACS
