Document Summary

Muscular compartments: vertebral muscles, abdominal muscles, breathing muscles, perineum & pelvic diaphragm muscles, many muscles aid the diaphragm in breathing, majority of the oxygen utilized during exercise is used by breathing muscles. The ventral and dorsal horns together form rami. Iliocostalis: from the ilium out to the costalis, superiorly, it fans out across the ribs. Longissimus: from the ilium to all the transverse processes of the vertebral column. Spinalis: from the ilium all the way up the spine. There"s a diamond shaped fascia at the small of the back: thoracolumbar fascia. This point is a tendon where many muscles from the back attach. Intricate muscles of the spine are also innervated by dorsal rami: transversospinalis muscles: some run from one vertebrae to the next, some skip over the vertebrae, causes lateral flexion and rotation. Intertransversarius: runs from one transverse process to the next. Rotatores: running from the spinous process to the transverse process of the vertebrae below it.
