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).

Nov 3, 2023 · The erector spinae comprise of many muscles and a lot of attachments. Simplify your learning by focusing on the key facts using Kenhub’s muscle anatomy and reference charts! Similar to the other erector spinae groups, iliocostalis muscles are innervated by the lateral branches of the posterior rami of the cervical, thoracic and lumbar spinal ...

They are also known as the sacrospinalis group of muscles. These muscles lie on either side of the spinous processes of the vertebrae and extend throughout the lumbar, thoracic, and cervical regions. The erector spinae is covered in the lumbar and thoracic regions by the thoracolumbar fascia, and in the cervical region by the nuchal ligament.

1 day ago · Many individuals with incomplete spinal cord injury (SCI) exhibit reduced volitional control of trunk muscles, such as impaired voluntary contractions of the erector spinae (ES), due to damage to the neural pathways regulating sensorimotor function. Studies using conventional bipolar electromyography (EMG) showed alterations in the overall, or global, activation of the …

The erector spinae is most massive in the lumbar and thoracic regions. In the lumbar region, it is deep to the latissimus dorsi; in the thoracic region, it is deep to the trapezius and rhomboids. Very little erector spinae is present in the neck. The erector spinae is the principal musculature that works when we bend forward.

Jan 10, 2024 · 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.

Jul 23, 2020 · The fibres of the erector spinae muscle have a vertical orientation through the cervical, thoracic and lumbar spines and they lie in a groove lateral to the vertebral column. Depending on the region determines what the muscles are covered in, for example the erector spinae in the cervical spine are covered by nuchal ligament, while those in the ...

May 24, 2020 · The erector spinae is not a single muscle but a group that consists of the spinalis, longissimus, and iliocostalis muscles deep in the back; these are further categorized according to their position – capitis (head), cervicis (neck), thoracis (thorax), and lumborum (lower back).

Jan 27, 2025 · The erector spinae muscles are essential for supporting the spine and maintaining posture. Location. The erector spinae muscles are located on either side of the vertebral column, extending from the sacrum and pelvis to the base of the skull. They lie deep to the thoracolumbar fascia, trapezius, latissimus dorsi, and rhomboids.

Mar 1, 2017 · Grade III postero-anterior mobilisation of the thoracic spine reduces thoracic erector spinae activity in participants with non-specific thoracic spine pain. The change in muscle activity is likely to be due to the actual joint mobilisation, as a comparable amount of pain relief was observed for the placebo group.
