aponeurosis
A strong, flat sheet of fibrous connective tissue that serves as a tendon to attach muscles to bone or as fascia to bind muscles together or to other tissues at their origin or insertion
An aponeurosis is a flat, sheet-like structure composed of strong fibrous tissue that attaches muscles to bones or other structures. It serves as a connective tissue that helps to transmit the force generated by a muscle to the attachment site. Aponeuroses can be found in various locations throughout the body, including the abdomen, pelvis, and thorax.
One of the well-known aponeuroses is the palmar aponeurosis, which is located in the hand. It is a broad, flat structure that covers the palm of the hand and attaches to the bones of the fingers. This aponeurosis plays a crucial role in shaping and supporting the hand.
Another important aponeurosis is the linea alba, which is a tough, fibrous band of tissue that runs vertically down the front of the abdomen, separating the left and right rectus abdominis muscles. The linea alba helps provide support for the abdominal muscles and protects the underlying organs.
Overall, aponeuroses play a vital role in connecting muscles to their intended attachment sites and providing support, stability, and strength to the body.
