Peritendinium (Peritendineum)

Peritendinium, or peritenonium (lat. peritendineum) is a fibrous sheath surrounding the tendon.

Peritendinium is a dense connective tissue that covers the outside of the tendon and lines the inside of the tendon sheath. The main function of peritendinium is to ensure the tendon slides inside the tendon sheath during muscle contraction.

In addition, the peritendinium performs a protective function, protecting the tendon from friction against the bone and articular capsule. It is also involved in providing nutrition to the tendon, as it contains blood vessels and nerves.

Damage or inflammation of the peritendinium can lead to the development of tendinitis or tenosynovitis.

The peritendinium sheath surrounds the tendons and provides them with protection from mechanical damage and environmental influences. The peritendium consists of dense fibrous tissue that contains collagen and elastin. It forms a membrane that separates the tendon from surrounding tissue and protects it from damage.

The peritendium performs many functions, including supporting the tendon, protecting it from mechanical damage, and regulating blood supply and metabolism. In addition, the peritendium is involved in the formation of connective tissues and plays an important role in wound healing and tissue regeneration.

When tendons and ligaments are injured, the peritendium can be damaged and cause pain and limited mobility. To restore the peritendium, it is necessary to provide access to the tendon and restore the integrity of the sheath.

Thus, the peritendinium is an important component of the musculoskeletal system and plays a key role in its functioning. Damage to it can lead to serious consequences, so it is important to pay attention to its protection and restoration in case of injury and illness.
