Muscle Sacrococcygeal Ventral

The ventral sacrococcygeal muscle is one of the muscles that is located in the area of ​​the sacrum and coccyx. It plays an important role in maintaining correct posture and stabilizing the spine.

The ventral sacrococcygeal muscle consists of two parts: medial and lateral. The medial part starts from the sacrum, passes through the coccyx and ends on the back of the thigh. The lateral part starts from the lateral surface of the sacrum and also ends on the thigh.

The main function of the ventral sacrococcygeal muscle is to maintain correct posture and stabilize the spine. It is also involved in leg movements such as hip flexion and extension.

To maintain health and prevent diseases, it is recommended to regularly engage in physical exercise, which includes exercises to strengthen the ventral sacrococcygeal muscles. It is also important to monitor your posture and avoid prolonged static body positions.

M. **Sacrospinous, -costal and ******-**coccal-**cyclical muscles***, ventr. - m. sacro costo-coccygeus, m. sacrotuberalis.*

A) Definition. The sacral** sacrospinous, -costal** and** -cok**cyclical* muscle* is a derivative of five embryonic folds: the first (medial) sacral fold; first (lateral) lumbar fold - **subcostal fold**; third (median) sacrolumbar fold; the second sacropelvic fold on one side and the sixth superior sacral fold on the other side. All four of these folds plunge into the mesenchyme at the beginning of the sacrum, and then gradually converge towards the coccyx

B). Branches. The *long* part of the muscle (more powerful**)** is divided into posterior (it enters the layer of the external transverse muscles of the gluteal region) and anterior branches, which give rise to connecting bundles in the layer of fascia separating the psoas major muscle from the quadratus femoris muscle, and m. tensor fasciae latae.

IN). Function. * With bilateral contraction, the sacrobrachial and sacrodorsal muscles straighten the torso, raising the pelvis. With unilateral contraction, the pelvic tilt to the side decreases. The anterior muscle attachments are involved in hip flexion. The coccygespinalis muscles, together with the part of the same name of the obturator externus muscle, raise the ischium and hip joint; the middle part of the external anal sphincter is raised and participates in peristalsis. The outer and inner parts of the lateral sacral muscles raise the pubic bone, the muscular cavity formed by its end and lower the pubic arch. Some of the fibers are involved in the formation of the tendon center of the perineum. In the area of ​​the sacrum, the coccygeal cavity of the small pelvis is straightened
