Ultrastructural study of myotendinous junction plasticity: from disuse to exercise

Effects of physical training on sarcomere lengths and muscle-tendon interface of the cervical region in an experimental model of menopause

“…For exerting the extreme ability of tissue plasticity and acting at the interface between the cells of skeletal muscle and tendinous cells, the MTJ exhibits a high level of morphological adaptations, such as an increase in the length and thickness of the sarcoplasmatic invaginations and evaginations resulting from physical exercise, aging, or development according to the function, angle, or topography of skeletal striated muscles. 27…”

Tendon injury and repair – A perspective on the basic mechanisms of tendon disease and future clinical therapy

“…This article focuses almost exclusively on the ''tendon proper", and leaves aside a detailed consideration of the highly specialized muscle-tendon [27][28][29] and tendon-bone junctions [30][31][32][33][34]. Nonetheless, the structure of tendon proper is tightly coupled to the architecture and function of the muscle to which it is attached.…”

“…At the muscle-tendon junction, tendon fibers fan out like a river delta. Although the mechanical and physiological interactions between tendon and muscle remain poorly understood [27], the junction provides a mechanically stable transition with large contact surface between both tissues.…”

Characterization of the mechanical properties of the mouse Achilles tendon enthesis by microindentation. Effects of unloading and subsequent reloading

“…The musculoskeletal system provides our body with movement. Tendons play a major role in bone segment mobility, transmitting muscle force to the bone through two interfaces: the myotendinous junction and the osteotendinous junction ( Curzi, 2016 ; Roffino et al, 2021 ). The latter, also called enthesis, is responsible for force transmission between two tissues with differing mechanical properties: the tendon (soft tissue) and the bone (hard tissue).…”
