senvävnadens

Senvävnadens refers to the connective tissue that forms tendons. Tendons are fibrous cords of collagen that attach muscles to bones, enabling movement. This tissue is characterized by its high tensile strength and limited elasticity, crucial for transmitting the force generated by muscle contractions to the skeletal system.

The primary component of senvävnadens is collagen, specifically type I collagen, which is organized into parallel bundles. These bundles are further organized into fascicles, and multiple fascicles make up the entire tendon. Fibroblasts, also known as tenocytes within the tendon, are responsible for synthesizing and maintaining the collagen matrix. A small percentage of tenocytes are found within the tendon, embedded in the extracellular matrix.

The structure of senvävnadens is highly organized to withstand mechanical stress. Blood supply to tendons is generally sparse, particularly in the mid-substance, which can affect healing processes. However, the enthesis, the area where the tendon attaches to bone, has a richer vascularization. Tendons are typically surrounded by a sheath or paratenon that facilitates gliding and reduces friction during movement.

Injuries to senvävnadens, such as tendonitis or tears, can be debilitating due to the tissue's limited capacity for repair. These injuries often result from overuse, sudden trauma, or aging. The biomechanical properties of senvävnadens are essential for efficient locomotion and overall musculoskeletal function.
