Muscle Gemini Inferior

Gemini inferior muscle

Name

The muscle received its name because of its unique location: on both sides of the femur in the pelvic area lies a muscle of the same shape. Therefore, it is called the arcuate transverse major inferior muscle of the foot. However, the name is assigned to it in Latin and is used in most medical sources and clinical recommendations. The gemellus inferior muscle is abbreviated as the gemminis muscle for ease of writing.

The gemini muscle supports the pelvic joint, prevents its excessive mobility and allows free movement. The muscles of the same name have an elongated shape and occupy the entire lower surface of the joints of the hip and pelvis. The intersection line passes at the border between the first and second ribs of the pelvis.

With the help of the twin muscles, a person abducts the hip and rotates the lower limb outward. There are two types: adductor (flexes the limb) and abductor (extends the limb). As a person grows, the structure of muscles changes. Normally, the twin muscles are evenly located under the pelvic and femur bones. But it is worth considering that different parts of the muscle are used to develop various motor functions. If its proximal or apical sections are used more for abduction, then the distal ones are used for adduction of the leg.

Localization

Both types of muscles are located in the back and make the waist round. From the lateral line, this part passes at the lower border of the pelvis and goes to the first costal arches of the lumbar region. The withdrawal of the muscles ends in the front half of the thigh at a distance of 5 cm above the knee. The mobility and flexibility of the pelvis depends on the endurance and work of the twin muscles. Thus, their prevention and timely diagnosis will help prevent diseases or complications associated with joint pathologies.
