The iliotibial tract or iliotibial band (ITB; also known as Maissiat's band or the IT band) is a longitudinal fibrous reinforcement of the fascia lata.The action of the muscles associated with the ITB (tensor fasciae latae and some fibers of gluteus maximus) flex, extend, abduct, and laterally and medially rotate the hip.
The gluteal muscles include the gluteus maximus, gluteus medius, gluteus minimus, and tensor fasciae latae.They cover the lateral surface of the ilium.The gluteus maximus, which forms most of the muscle of the buttocks, originates primarily on the ilium and sacrum and inserts on the gluteal tuberosity of the femur as well as the iliotibial tract, a tract of strong fibrous tissue that runs ...
An A-band contains the entire length of a single thick filament. The anisotropic band contains both thick and thin filaments. Within the A-band is a paler region called the H-zone (from the German "heller", brighter). Named for their lighter appearance under a polarization microscope. H-band is the zone of the thick filaments that has no actin.
The IT band, iliotibial band, feels painful when nearby muscles are tight. Here's how to stretch the IT band effectively per a physical therapist. You Can Stretch Your IT Band Without Getting Out ...
The tensor fasciae latae (or tensor fasciæ latæ or, formerly, tensor vaginae femoris) is a muscle of the thigh. Together with the gluteus maximus, it acts on and is continuous with the iliotibial band, which attaches to the tibia. The muscle assists in keeping the balance of the pelvis while standing, walking, or running.
Iliotibial band syndrome is one of the leading causes of lateral knee pain in runners. The iliotibial band is a thick band of fascia composing the tendon of the tensor fasciae latae muscle. It is located on the lateral aspect of the knee, extending from the outside of the pelvis, over the hip and knee, and inserting just below the knee. The ...
It provides attachment for the inguinal ligament, the sartorius muscle, [1] [4] and the tensor fasciae latae muscle. [2] [3] A variety of structures lie close to the anterior superior iliac spine, including the subcostal nerve, [5] the femoral artery (which passes between it and the pubic symphysis), [4] and the iliohypogastric nerve.

In physiology, isotropic bands (better known as I bands) are the lighter bands of skeletal muscle cells (a.k.a. muscle fibers). Isotropic bands contain only actin-containing thin filaments. [1] The thin filaments are placed between 2 myosin filaments and contain only the actin filaments of neighboring sarcomeres. Bisecting the I band and ...
