Tendon the Achilles tendon stretches as the ankle joint dorsiflexes. During the last portion of the stride, as the foot plantar-flexes (pointing the toes down), the stored elastic energy is released. Furthermore, because the tendon stretches, the muscle is able to function with less or even no change in length, allowing the muscle to generate greater force. The mechanical properties of the tendon are dependent on the collagen fiber diameter and orientation. The collagen fibrils are parallel to each other and closely packed, but show a wave-like appearance due to planar undulations, or crimps, on a scale of several micrometers. In
Tendon reflex over the entire muscle by preventing “muscle fibers connected with overstimulated tendon organs so that their contraction is more comparable to the contraction of the rest of the muscle.” Tendon reflex Tendon reflex (or T-reflex) may refer to: To test the reflex, tap on the tendon. In a healthy individual the intensity on both sides is equal. This means that the connections between the spinal cord and the muscles are undamaged. Main Spinal Nerve Roots Involved: The Golgi tendon reflex is a response to extensive tension on a tendon. It helps avoid strong muscle contractions which could tear the tendon
