“…The ventral approach was applied for visualization of RDNSs, instead of the dorsal approach, just as suggested by the literature (4,6). This is because finding the origins of the spinal nerves and tracing the spreading of the branches from the ventral side of the vertebral column to the dorsal side was easy at the gross anatomical level.…”

“…Demographic data of the cadavers are given in the Table. The trunks of the cadavers were firstly divided longitudinally into 2 equal components at the medial plane. The ventral approach was chosen to dissect and reveal a detailed image of the total nerve layout at gross level, just as suggested by the literature (4,8). Having removed the vertebral bodies by sawing of the pedicles of the related side, the iliopsoas muscle, transverse process, spinal cord together with the meninges, and dorsal roots with the spinal ganglion and ventral roots were displayed.…”

“…Nowadays, the intermediate branch of the dorsal rami has been shown through applying the ventral approach for visualization of RDNSs, instead of dissecting them from the back of the body (the dorsal approach), in humans (4) and other animals including dolphins (8). These studies have reported that the intermediate branch contributes mostly to the innervations of the longissimus muscle, partly the iliocostalis muscle, and relevant skin.…”

The majority of anatomy textbooks do not describe these nerves in detail, which may be attributable to the fact that for many years they were regarded as structures of minor clinical importance. The state of knowledge on these nerves has changed within the last 30 years. Attention has been turned to their function and importance for both diagnostic practice and therapy of lower back pain.Summarising the available literature, we may conclude that the medial and lateral branches separate at the junction of the facet joint and the distal upper edge of the transverse process; that the size, course and area supplied differ between the lateral and the medial branch; and that facet joints receive multisegmental in...

Development of the epaxial muscles in the human embryo

et al. 2016

Although the intrinsic muscles of the back are defined by their embryological origin and innervation pattern, no detailed study on their development is available. Human embryos (5-10 weeks development) were studied, using Amira3D® reconstruction and Cinema4D® remodeling software for visualization. At Carnegie Stage (CS)15, the epaxial portions of the myotomes became identifiable laterally to the developing vertebrae. At CS16, these portions fused starting cranially to form a longitudinal muscle column, which became innervated by the dorsal branches of the spinal nerves. At CS17, the longitudinal muscle mass segregated into medial and lateral columns (completed at CS18). At CS18, the medial column segregated again into intermediate and medial columns (completed at CS20). The lateral and intermediate columns did not separate in the lower lumbar and sacral regions. Between CS20 and CS23, the cervical portions of the three columns segregated again from lateral to medial resulting ventrolaterally in rod-like continuations of the caudal portions of the columns and dorsomedially in spade-like portions. The observed topography identifies the iliocostalis and splenius as belonging to the lateral column, the longissimus to the intermediate column, and the (semi-)spinalis to the medial column. The medial (multifidus) group acquired its transversospinal course during closure of the vertebral arches in the early fetal period. Hence, the anatomical ontology of the epaxial muscles is determined by craniocaudal and lateromedial gradients in development. Three longitudinal muscle columns, commonly referred to as the erector spinae, form the basic architectural design of the intrinsic muscles of the back. Clin.
