Introduction. there are three major groups of back muscles: superficial: attached to the shoulder girdle. intermediate: attached to the posterior thorax. deep: attached to the vertebral column. the first two groups ( superficial and intermediate) are referred to as the extrinsic back muscles. the deep group is the intrinsic muscle group. There are three major groups of back muscles: superficial: attached to the shoulder girdle. intermediate: attached to the posterior thorax. deep: attached to the vertebral column. the first two groups ( superficial and intermediate ) are referred to as the extrinsic back muscles. the deep group are the intrinsic muscle group.

It is the most superficial of all the back muscles. attachments: originates from the skull, ligamentum nuchae and the spinous processes of c7 t12. the fibres attach to the clavicle, acromion and the scapula spine. innervation: motor innervation is from the accessory nerve. it also receives proprioceptor fibres from c3 and c4 spinal nerves.

There are three major groups of back muscles : superficial: attached to the shoulder girdle. intermediate: attached to the posterior thorax. deep: attached to the vertebral column, also known as the intrinsic muscle group [1] these groups serve to allow: flexion extension, rotation, and side bending of the back; movement of the limbs; locomotor. 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 extrinsic (superficial) back muscles, which lie most superficially on the back.
