Jänneväliin

Jänneväliin is a Finnish term that translates to "intertendon" or "between the tendons." It refers to the space or region located between two or more tendons. This anatomical area is often filled with connective tissue, fat, and sometimes bursae, which are small fluid-filled sacs that reduce friction. The jänneväliin plays a role in the smooth movement of muscles and their associated tendons, allowing them to glide past each other without undue resistance. Understanding the anatomy of the jänneväliin is important in fields such as medicine, particularly in orthopedics and sports medicine, as inflammation or injury in this region can lead to pain and restricted movement. For example, conditions like tenosynovitis, which is inflammation of the sheath surrounding a tendon, can affect the jänneväliin. The specific structures present within a jänneväliin can vary depending on its location in the body, but its fundamental function remains consistent: facilitating unimpeded tendon action.
