What muscles make up the erector spinae. Spinalis longissimus and iliocostalis.
It consists of several muscles longissimus thoracis iliocostalis multifidi rotatores and runs on and parallel to the spine.
Erector spinae muscle group. The two major functions of the erector spinae muscle group are to extend and laterally flex the spine. These muscles work on different parts of the back to allow for aerobic movements like. Erector spinae muscle Musculus erector spinae The erector spinae muscles comprise the intermediate layer of the deep intrinsic muscles of the back.
They extend on either side of the vertebral column between the base of the cranium superiorly and pelvis inferiorly. The erector spinae are divided into three groups from medial to lateral. The erector spinae muscle group consists of a number of different muscles ie.
Lumborum thoracis cervicis longissimus. Thoracis cervicis capitis spinalis. Thoracis cervicis capitis semispinalis.
Thoracis cervicis capitis multifidi rotatores. Thoracis longus thoracis brevis interspinales intertransversarii. The erector spinae muscles are really three muscles.
Spinalis longissimus and iliocostalis. To get more specific anatomists subdivide each of these three muscles into smaller muscles based on the region of the spine they are in. Spinalis comes from the Latin word spina which means thorn.
The erector spinae muscles are a group of nine different muscles located in the lower backspine area of the body. Since there are so many muscles that make up the erector. The Three Muscle Groups of Erector Spinae.
The erector spinae collectively are the muscles that support the spine keep it upright and stable and also extend and rotate. The easiest place to start is by recognizing the three main groups where they are located and what actions they each perform. Then those groups get further divided into specific functions and locations on along the spine.
The erector spinae is a group of muscles and tendons that connect your entire back from your hips and sacrum lower backlumbar to the base of your skull cervical region. The muscles of your erector spinae line both sides of your spine and they are in charge of many functions like lateral flexion and extension and side-to-side rotation. The erector spinae muscle also known as sacrospinalis and extensor spinae in some texts is from the deep muscles of the back.
It lies superficial to the transversospinales muscle group and deep to the intermediate group of back muscles serratus posterior superior and inferior. What muscles make up the erector spinae. The erector spinae muscles are a group of muscles that belong to an even broader group of muscles called the paraspinal muscles.
You can get a sense from breaking down the name where this larger group of muscles is located. Para means alongside or beside. Spinal of course refers to the spine.
The erector spinae muscle group runs the length of the spine parallel to the vertebral column occupying the intermediate layer of the back muscles. It has attachments to the skull cervical thoracic and lumbar vertebrae the ileum and the sacrum. Spinalis is the most medial of the three erector spinae muscles.
The longissimus attaches superiorly to the articular andor posterior tubercles of the transverse processes of C2 -C7 and the mastoid process of the temporal bone. The spinalis in the neck attaches from the spinous processes of C2 to the spinous process of C7. As a group the erector spinae extends laterally flexes and ipsilaterally rotates.
Three muscles essentially make up the erector spinae making it a muscle group – not a singular muscle. All of the muscles perform the same action which is to extend the spine but they do it in different areas of the back. The three columns of the erector spinae group have a common origin the sacrum the ribs and all vertebrae lumbar and thoracic.
Insertion The insertion is on the ribs the cervical and thoracic vertebrae the skull mastoid process and occipital bone. The Erector Spinae is a group of muscles Iliocostalis Longissimus Spinalis that attach from the back of pelvis torso and neck.

It consists of several muscles longissimus thoracis iliocostalis multifidi rotatores and runs on and parallel to the spine. It can be divided into two groups the lateralouter tract and the medialinner tract. The erector spinaes primary function is to extend the back in a way that makes the chest move forward and the head move posteriorly.
It keeps the spine erect and also helps laterally rotate the spine. What Is the Erector Spinae. The Erector Spinae is a group of muscles that run vertically beside the spine.
Composed of the Iliocostalis Longissimus and Spinalis this muscle group is also known as the I like standing muscles due to their function. Three main muscles compose the Erector Spinae. Erector Spinae also called the sacrospinalis muscle group the spinal erectors or the lower back muscles refers to the group of muscles and also the tendons that connect your back all the way from the hips at the Iliac Crest and Sacrum areas lower back to the base of the skull or the cervical region.
The erector spinae group runs from the sacral area and pelvis all the way up to the occipital bone Kendall et al. This creates a very long muscle group and is consequently beneficially stretched in separate segments of the lumbar thoracic and cervical areas. Stretch of the erector spinae muscle group.
