The erector spinae is not just one muscle, but a group of muscles and tendons which run more or less the length of the spine on the left and the right, from the sacrum, or sacral region, and hips to the base of the skull. They are also known as the sacrospinalis group of muscles.

The erector spinae (ES) is one of the core and paraspinal muscles, is a large and superficial muscle that lies just deep to the thoracolumbar fascia and arises from the erector spinae aponeurosis (ESA).

2023年11月3日 · Erector spinae muscles are deep muscles of the back that extend and laterally flex the spine. Learn more about their anatomy and function at Kenhub!

2024年1月10日 · The erector spinae, also known as the sacrospinalis, is a group of muscles comprising the middle or intermediate layer of the intrinsic or deep back muscles. The name literally means ‘spinal erectors,’ with the group including 3 muscles that span the entire length of the spinal column.

2020年5月24日 · Erector spinae muscles or paraspinal muscles run vertically along the spinal vertebrae and work to stabilize the back from the lower sacral to the cervical vertebrae and enable spinal flexion, extension, and rotation.

2025年1月27日 · The erector spinae muscles are a group of three vertically oriented muscles that span the length of the vertebral column. These muscles are positioned in the intermediate layer of the intrinsic back muscles and are vital for maintaining spinal structure and mobility.

Erector spinae, a deep muscle of the back; it arises from a tendon attached to the crest along the centre of the sacrum (the part of the backbone at the level of the pelvis, formed of five vertebrae fused together). When it reaches the level of the small of the back, the erector divides into three.

Three muscles are part of the erector spinae: the iliocostalis, longissimus, and spinalis. Each of these muscles is a group in an of itself, with a portion of each muscle in the low back, middle back, and neck.

Erector spinae muscles, also referred to as the sacrospinal muscle group, is one such muscle group that primarily acts as an extensor. It consists of three muscles that help in extending the vertebral column. This muscle group runs from the base of the skull to the sacrum.

2014年4月18日 · As you can see from the picture, the lower back is made up of the erector spinae muscles, also known as extensor spinae, spinal erectors, spinal extensors, and sacrospinalis. These muscles run alongside the entire length of the spinal column (from the base of the spine all the way to the neck bones).
