The direction of the microfibrils is called microfibril angle (MFA). In the secondary cell wall of fibres of trees a low microfibril angle is found in the S2-layer, while S1 and S3-layers show a higher MFA . However, the MFA can also change depending on the loads on the tissue. It has been shown that in reaction wood the MFA in S2-layer can ...

It has a low stiffness ~0.6MPa but a high energy restoring percentage ~98%, and efficiently helps flying insects to flap wings or fleas to jump. Spider silk fibril is composed of stiff crystallized β-sheets structure, responsible for strength, and amorphous matrix surrounding, improving toughness and elongation ability. [ 16 ]
It forms the "forearm" of the horse along with the ulna. Ulna: caudal to the radius, it is fused to that bone in an adult horse. Shoulder joint (scapulohumeral joint): usually has an angle of 120-130 degrees when the horse is standing, which can extended to 145 degrees, and flexed to 80 degrees (such as when the horse is jumping an obstacle).
The horse is most suited for pleasure riding, low-impact, and low speed events * The medial supporting ligaments of the carpus will be under excess tension. May cause soundness problems in the carpals or supporting ligaments. Horse also tends to toe-out, causing those related problems.
