A tendon is made of dense regular connective tissue, whose main cellular components are special fibroblasts called tendon cells (tenocytes). [3] Tendon cells synthesize the tendon's extracellular matrix, which abounds with densely-packed collagen fibers. The collagen fibers run parallel to each other and are grouped into fascicles.
The fibers are mainly composed of type I collagen. Crowded between the collagen fibers are rows of fibroblasts, fiber-forming cells, that generate the fibers. Dense connective tissue forms strong, rope-like structures such as tendons and ligaments. Tendons attach skeletal muscles to bones; ligaments connect bones to bones at joints.
In cord arrangement, bundles of collagen and matrix are distributed in regular alternate patterns. In sheath arrangement, collagen bundles and matrix are distributed in irregular patterns, sometimes in the form of a network. It is similar to areolar tissue, but in DRCT elastic fibers are completely absent. [2]
An aponeurosis (/ ˌ æ p ə nj ʊəˈr oʊ s ɪ s /; pl.: aponeuroses) is a flattened tendon [1] by which muscle attaches to bone or fascia. [2] Aponeuroses exhibit an ordered arrangement of collagen fibres, thus attaining high tensile strength in a particular direction while being vulnerable to tensional or shear forces in other directions. [1]
Limited tests have been done on the tensile strength of the collagen fiber, but generally it has been shown to have a lower Young's modulus compared to fibrils. [55] When studying the mechanical properties of collagen, tendon is often chosen as the ideal material because it is close to a pure and aligned collagen structure. However, at the ...
Many of the muscle fibers end within the muscle and do not connect to the tendon directly, thus necessitating a force transmission pathway via the endomysium. The planar network of the collagen fibers appears to be randomly distributed at first glance, but detailed analysis has shown that the network is not truly random and that there is a ...
Endomysium combines with perimysium and epimysium to create the collagen fibers of tendons, providing the tissue connection between muscles and bones by indirect attachment. [4] It connects with perimysium using intermittent perimysial junction plates. [5] Collagen is the major protein that composes connective tissues like endomysium. [6]
Type I collagen is the most abundant collagen of the human body, consisting of around 90% of the body's total collagen in vertebrates. Due to this, it is also the most abundant protein type found in all vertebrates. Type I forms large, eosinophilic fibers known as collagen fibers, which make up most of the rope-like dense connective tissue in ...
