Muscles (muscular system)

Intertransverse muscles of the lower back, chest and neck

The intertransverse muscles of the lumbar, thoracic and neck (mm. intertransversarii lumborum, thoracis et cervicis) are formed by short bundles connecting the transverse processes of adjacent vertebrae and are better expressed at the level of the lumbar and cervical spine.

Suboccipital muscles

The suboccipital muscles (mm. suboccipitales) include the large posterior rectus capitis muscle, the small posterior rectus capitis muscle, the superior and inferior oblique capitis muscles.

Back muscles

The back muscles (musculi dorsi) are paired and occupy the entire dorsal side of the body, starting from the sacrum and adjacent parts of the iliac crests to the base of the skull. Arranged in layers, these muscles have complex anatomical and topographic relationships due to the peculiarities of their development and function.

Torso muscles

The muscles of the trunk are divided into the muscles of the back, chest and abdomen. The posterior regions of the trunk (regiones dorsales) cover the entire posterior surface of the trunk. The upper border of the back is the external occipital protuberance and the superior nuchal line of the occipital bone. The lower border is the level of the sacroiliac joints and the coccyx.

Muscles

Skeletal muscles, attaching to bones, set them in motion, participate in the formation of the walls of body cavities: oral, thoracic, abdominal, pelvic, are part of the walls of some internal organs (pharynx, upper part of the esophagus, larynx), are among the auxiliary organs of the eye (oculomotor muscles), have an effect on the auditory ossicles in the tympanic cavity.
