külgmiseljad

Külgmiseljad, often translated as "side saddle" or "cruralis" in anatomical contexts, refers to muscles located in the lateral or outer aspect of the thigh. These muscles play a crucial role in hip and knee movement, contributing to stability and locomotion. The primary muscles typically grouped under the külgmiseljad are the vastus lateralis and the iliotibial band.

The vastus lateralis is one of the four quadriceps muscles and is situated on the outer side of the thigh. It originates from the femur and inserts into the patella via the quadriceps tendon. Its main function is to extend the knee joint, allowing for straightening of the leg. It also contributes to maintaining posture and balance.

The iliotibial band, or IT band, is a thick, fibrous band of connective tissue that runs along the outside of the thigh, from the hip to just below the knee. While not a muscle itself, it is closely associated with the külgmiseljad, particularly the tensor fasciae latae muscle which attaches to its upper portion. The IT band helps to stabilize the hip and knee joints, particularly during walking and running, and also aids in abduction and rotation of the thigh.

Dysfunction or tightness in the külgmiseljad can lead to conditions like iliotibial band syndrome, characterized by pain on the outer side of the knee or hip, often experienced by athletes involved in repetitive leg movements.
