The chief pathology associated with the back muscles is pain. These muscles can develop spasms that can be debilitating. The lower back muscles are a common cause of low back pain. This entity is often mistaken for spinal stenosis and involves millions of people of all ages and gender. Patien...
The interplay between the extrinsic back muscles allows for a wide range of motions. The muscles' arrangement enables complex actions like reaching, lifting, pulling, and pushing. The specific functions of each extrinsic back muscle are explained below. The trapezius works with other muscles to move...
Back muscles The muscles of the back are a group of strong, paired muscles that lie on the posterior aspect of the trunk. They provide movements of the spine, stability to the trunk, as well as the coordination between the movements of the limbs and trunk.The back muscles are divided into...
If your back muscles are weak, they won't be able to optimally support and stabilise your spine. Chances are your body will cope with this weakness by compromising good posture. Your shoulders will slump forwards and your lower back can round, leading to stiffness and pain over time. "Think...

Hypoglossal nerve: all tongue muscles except for the palatoglossus Vagus nerveVagus nerveThe 10th cranial nerve. The vagus is a mixed nerve which contains somatic afferents (from skin in back of the ear and the external auditory meatus), visceral afferents (from the pharynx, larynx, thorax, an...
The bones of the trunk and the lower limb are so arranged in modern humans that standing upright requires a minimum of muscle activity. Some muscles, however, are essential to maintaining balance, and the extensors of the knee have been rearranged and realigned, as have the muscles of the ...
