Back Muscle Names Locations Muscles Of The Back Teachmeanatomy

Muscles Of The Back Teachmeanatomy The muscles of the back can be arranged into 3 categories based on their location: superficial back muscles, intermediate back muscles and intrinsic back muscles.the intrinsic muscles are named as such because their embryological development begins in the back, oppose to the superficial and intermediate back muscles which develop elsewhere and are therefore classed as extrinsic muscles. Attachments: arises from the common tendinous origin, and attaches to the spinous processes of c2, t1 t8 and the occipital bone of the skull. innervation: posterior rami of the spinal nerves. actions: acts unilaterally to laterally flex the vertebral column. acts bilaterally to extend the vertebral column and head.

Muscles Of The Back Teachmeanatomy The serratus posterior superior is a thin, rectangular shaped muscle. it lies deep to the rhomboid muscles on the upper back. attachments: originates from the lower part of the ligamentum nuchae, and the cervical and thoracic spines (usually c7 – t3). the fibres pass in an inferolateral direction, attaching to ribs 2 5. actions: elevates ribs. Intermediate muscles (2) have attachments on the ribs and help in moving the thoracic cage. they are usually included in the chest muscle group. serratus posterior (2) — serratus posterior inferior. lower back, just above the lumbar region, beneath the latissimus dorsi. the spinous processes of t11 l2 vertebrae. Semispinalis, multifidus and rotatores make up the transversospinal muscle group. semispinalis. transverse processes of c7 t12. capitis: back of skull between nuchal lines; cervicis & thoracis: spines 4 6 vertebrae above origin. extends the trunk and laterally bends the trunk, rotates the trunk to the opposite side. 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.

The Intrinsic Back Muscles Attachments Actions Teachmeanatomy Semispinalis, multifidus and rotatores make up the transversospinal muscle group. semispinalis. transverse processes of c7 t12. capitis: back of skull between nuchal lines; cervicis & thoracis: spines 4 6 vertebrae above origin. extends the trunk and laterally bends the trunk, rotates the trunk to the opposite side. 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. Back anatomy. the back is the body region between the neck and the gluteal regions. it comprises the vertebral column (spine) and two compartments of back muscles; extrinsic and intrinsic. the back functions are many, such as to house and protect the spinal cord, hold the body and head upright, and adjust the movements of the upper and lower limbs. The first subgroup consists of two superficial muscles: the trapezius and latissimus dorsi. the trapezius is a large triangular muscle that covers the posterior aspect of the neck and the superior half of the back. there are two trapezius muscles in the back, which when seen together, look like a trapezium. proximally, the trapezius originates.
