Introduction[edit | edit source]

Myotendinous junction (MTJ) is a part of the myotendinous unit, which connects muscle and tendon, and transmits forces between them.

The MTJ has a unique morphology with a highly folded muscle membrane filled with invaginations of collagen fibrils from the tendon. This creates an increased area of force transmission between muscle and tendon and, as a result, disperses the energy of a contracting muscle decreasing focal stress[1][2].
