This morphology in hagfishes is a clear contrast to the taut, close-fitting skins of other fishes (lampreys and cartilaginous and bony fishes) that possess firm myoseptal fiber attachments between the axial muscles
and skin (Fig.
We found out that patients who exhibited axial muscle
weakness had earlier disease onset ages than those who did not, and a study about LOPD in 54 Dutch patients  also revealed that the patients with scoliosis experienced theirfirst complaints before 21 years of age, while the mean age for all 54 patients was 28.1 [+ or -] 14.3 years.
Function of red axial muscles
of carp (Cyprinus carpio): recruitment and normalized power output during swimming in different modes.
Identified motoneurons and their innervation of axial muscles
in the zebrafish.
Sequential activation of axial muscles
during different forms of rhythmic behavior in man.
 SPS initially presents as muscle stiffness, which is progressive and usually involves rigidity of the axial muscles
, including the paraspinal thoracic, lumbar and proximal leg muscles.
