Introduction[edit | edit source]
Aponeuroses are sheet-like elastic tendon structures that cover a portion of the muscle belly and act as insertion sites for muscle fibers while free tendons connect muscles to bones[1]. They have a role similar to a tendon but here is how they differ:
- An aponeurosis looks quite different than a tendon. An aponeurosis is made of layers of delicate, thin sheaths. Tendons, in contrast, are tough and rope-like. An aponeurosis is made primarily of bundles of collagen fibers distributed in regular parallel patterns, which makes an aponeurosis resilient.
- Aponeurosis has a function of absorbing energy during the movement of the muscle, while Tendon has a function of stretching and contracting during muscle movements.
- It is very rare for the Aponeurosis to get injured as it is situated hidden under many layers of bones and muscles. But Tendon gets injured easily, for it is present in all the injury-prone areas.
- Aponeuroses can act as fascia. Fascia is a fibrous tissue that envelopes muscles or organs, to bind muscles together or to other tissues.[2][3].
