The iliocostals cervicis (cervicalis ascendens) consists of several muscle straps that originated from the angles of the upper six ribs. The muscle straps have a number of tendons, varying in different individuals, which insert in the transverse processes of the middle cervical vertebrae. The muscle is innervated by dorsal branches of the thoracic nerve and supplied by branches from the aorta. The illiocostalis consists of three subdivisions: iliocostalis lumborum, iliocostalis thoracis, and iliocostalis cervicis. These muscles are a part of the external portion of the long erector spinae muscle group. Research Iliocostalis Cervicis
The iliocostals lumborum consists of several muscle straps that link the lumbar vertebrae and sacrum with the lower six or seven ribs. The muscle straps have a number of tendons, varying in different individuals, which insert in all angles in the lower six ribs. The muscle is innervated by dorsal branches of the lumbar and thoracic nerves and supplied by branches from the aorta. Research Iliocostalis Lumborum
The iliocostals thoracis (iliocostalis dorsi) consists of several muscle straps that link the thoracic vertebrae and sacrum with the lower six or seven ribs. The muscle straps have a number of tendons, varying in different individuals, which insert in all angles in the lower six ribs. The muscle is innervated by dorsal branches of the thoracic nerve and supplied by branches from the aorta. The illiocostalis consists of three subdivisions: iliocostalis lumborum,
iliocostalis thoracis, and iliocostalis cervicis. These muscles are a part of the external portion of the long erector spinae muscle group. Research Iliocostalis Thoracis
