General information
The lateral tract is made up of a complex of long muscles. A distinction is made between the saccrospinal (M. iliocostalis and M. longissimus), spinotransversal (Mm. intertransversarii and levatores costarum) and intertransversals (Mm. intertransversarii and levatores costarum) System.
A schematic drawing of the muscles (M. iliocostalis, M. longissimus etc.) can be displayed by clicking on the respective name in the "WebViewer".
Sacrospinal System
| M. iliocostalis | M. longissimus | |
| origin | 1) M. iliocostalis lumborum: Fascia thoracolumbalis, Os sacrum, Crista iliaca 2) M. iliocostalis thoracis: 7th-12th rib 3) M. iliocostalis cervicis: 3rd-7th rib |
4) M. longissimus thoracis: spinous processes of the lumbar spine, transverse processes of the lower section of the thoracic spine, Os sacrum, Crista iliaca 5) M. longissimus cervicis: 1st-6th thoracic vertebrae (transverse processes) 6) M. longissimus capitis: 1st-3rd thoracic vertebrae (transverse processes) and 4th-7th cervical vertebrae (transverse and articular processes) |
| insertion | 1) 6th-12th rib, transverse processes of the upper lumbar spine, Fascia thoracolumbalis 2) 1st-6th rib 3) 4th-6th cervical vertebrae (transverse processes) |
4) 2th-12th rib, transverse processes of the thoracic spine, rib processes of the lumbar spine 5) 2nd-5th cervical vertebrae (transverse processes) 6) Wart process (Proc. mastoideus) of the temporal bone (Os temporale) |
| function | In case of one-sided contraction these muscles cause lateral flexion on the same side of the body (ipsilateral), in case of bilateral activation dorsal extension. | The M. longissimus additionally causes a rotation of the head to the ipsilateral side. |
| innervation | lateral branches of the Rami posteriores spinal nerves (C8-L1) | lateral branches of the Rami posteriores spinal nerves (C1-L5) |

Spinotransverse and intertransverse system
| M. splenius | Mm. intertransversarii | Mm. levatores costarum | |
| origin | 7) M. splenius cervicis: 3rd-6th thoracic vertebra (spinous processes) 8) M. splenius capitis: 3rd cervical to 3rd thoracic vertebra (spinous processes) |
9) Mm. intertransversarii medial lumborum: between adjacent Procc. mamillares of the lumbar spine 10) Mm. intertransversarii lateral lumborum: between adjacent Procc. costales of the lumbar spine 11) Mm. intertransversarii posterior cervicis: between adjacent Tubercula posteriora of the 2nd-7th cervical vertebra |
12) Mm. intertransversarii costarum breves: 7th cervical and 1st-11th thoracic vertebrae (transverse processes) 13) Mm. intertransversarii costarum longi: 7th cervical and 1st-11th thoracic vertebrae (transverse processes) |
| Ansatz | 7) 1. und 2. Halswirbel (Dornfortsätze) 8) Proc. mastoideus, obere Nackenlinie (laterale Linea nuchalis |
9) bis 11) Ansätze und Ursprünge sind deckungsgleich | 12) Rippenwinkel (Angulus costae) der darunterliegenden Rippe 13) Rippenwinkel (Angulus costae) der übernächsten Rippe |
| Funktion | Bei beidseitiger Aktivierung bewirken diese Muskeln eine Dorsalextension der Halswirbelsäule, bei einseitiger Kontraktion Rotation und ipsilaterale Lateralflexion. | Die einseitige Aktivierung dieser Muskeln führt zur Lateralflexion der Lenden- und Halswirbelsäule, die beidseitige Kontraktion zur Stabilisierung und Dorsalextension der Lenden- und Halswirbelsäule | Die beidseitige Kontraktion bewirkt eine Dorsalextension der Brustwirbelsäule, die einseitige eine ipsilaterale Flexion und kontralaterale Rotation. |
| Innervation | laterale Zweige der Rami posteriores der Spinalnerven (C1-C6) | laterale Zweige der Rami posteriores und dem entsprechenden Rückenmarkssegment | Rami posteriores der Spinalnerven |
