Tendon from Different Anatomical Positions Essay -- Anatomy, Tissues

anatomical structure of a tendon is made up of collagenous tissues, a tough protein constituted as a large portion of the organic shew substance of bone and cartilage (Nordin & Frankel, 2001). Also termed extracellular matrix (ECM) consisting of few cells, 20% of cellular material is occupied as total tissue volume, whilst 80% accounts for extracellular matrix (approximately 70% piss and 30% solids) (Nordin & Frankel, 2001). Contained within these solids is a ground give care substance with minor components of elastin. Due to the dense interrelatedness tissue of collagen it is able to sustain stability over which the mechanics of the musculoskeletal system requires. This may be in the form of fibril, whereby, collagen molecules (type 1 collagen) be synthesized and secreted by fibroblasts (France , 2010). Procollagen is formed and further condensed to tropocollagen as the basic building freeze down of collagen (France , 2010).Across the parallel network leading to the developm ent of fibril cross-links atomic number 18 formed within collagen type 1. The cross-links allow tissues to withstand strength and position under mechanical var. (Fratzl, 2008). The solids within the extracellular contain ground like substance proteogly abides (PG). PG molecules binds extracellular water of the tendons, ensuring the matrix is a hydrated-gel like material (Nordin & Frankel, 2001). Thereby the substance acts as an adhesive between microfibrils in bundles stabilizing collagenous tissue forming connective tissue fascicles (appendix, figure 1). The functionality of tendons can be expressed by its materialization primarily to transmit index from muscle to bone. During any form of movements the tendons encounter forces such as longitudinal, thwartwise and rotational (Kannus, 200... ...llagen tissue cross-links across maturation revealing the number of cross-links lessen with growth. This suggests that a state of maturation cross-links are stabilsed to a non-reduci ble form (Robins et al, 1973).When stress is placed on tendons tissue must adapt to stiffen and spike in response to the physical demands placed on them. Physical knowledge during eccentric forces has been found to increase tensile strength of the tendons (Woo et al, 1981). Long periods of inaction can disrupt the parallel structure of collagen fibers in the tendons, decrease water content, although increase collagen cross-linking (Loitz et al, 1989). The collagen turnover increases although reports suggest the amount of tendon components and overall citizenry is unchanged. Ultimately immobilization decreases tendon stiffness, failure load and strength (Matsumoto et al, 2003).
