Jäänne

Jänne is a Finnish noun meaning tendon, the fibrous connective tissue that attaches a muscle to a bone. In human anatomy, a jänne transmits the force generated by muscle fibers to the skeleton, enabling movement. Tendons are predominantly made of tightly packed collagen fibers and have a relatively limited blood supply, which can make healing after injury slow. Common injuries include tendinopathies and partial or full tears, often caused by overuse or sudden overload. Treatments range from rest and physical therapy to surgical repair in severe cases.

In Finnish medical and educational contexts, jänne is used to reference tendons as part of the musculoskeletal system. The term is typically translated into English as tendon or sinew. Finnish speakers also form compounds such as lihasjänne (the tendon of a muscle) to describe specific tendons within the body.

Etymology and usage notes: the word jänne is a native Finnish term without widespread acceptance as a loanword from another language. It appears across clinical descriptions, anatomy texts, and everyday language when people discuss the body's connective structures.

Overall, jänne denotes the biological tendon, a key component in movement and force transmission, and is a basic term in Finnish anatomy and physiology.
