One of the newest techniques that have been described recently is the erector spinae plane (ESP) block. It was first described by Forero et al. [1] in 2016 for the treatment of chronic thoracic neuropathic pain and postoperative pain in thoracic surgery.

How is erector spinae named?

So, the word erector then refers to erect, or upright. And, the word spinae refers to the spine. The erector spinae muscles are really three muscles: spinalis, longissimus, and iliocostalis.

What is the origin and insertion of erector spinae?

It has three parts: spinalis thoracis which originates from the spinous process of L3-T10 and inserts in the spinous process of T8-T2. spinalis cervicis originates from the spinous process of T2-C6 and inserts in the spinous process of C4-C2.

What is meant by the common origin of the erector spinae?

origin: common origin. The spinalis runs from the lumbar region and attaches to the spinous proceses of the cervical region. which erector spinae muscle is able to rotate the head to the same side and why. longissimus capitis. able to do so because of its insertion into the mastoid.

What is erector spinae?

Introduction. 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).

Where are your Erectors?

The muscles and tendons of your erector spinae are located on both sides of your vertebral column (the bony points of the spine), which runs from your sacral and lumbar (lower back) to your thoracic (middle back) to your cervical region (upper back and neck).

Why are my spinal erectors so tight?

The muscles are made up of several smaller muscles, each spanning across a few spinal vertebrae providing stability from the lower back all the way to the top of the neck. When the erector spinae muscles are chronically tight it's often because of some weakness that has developed in another muscle or muscles.

Is Multifidus part of erector spinae?

Erector spinae and multifidus

The erector spinae muscles produce the extensor force needed for lifting, whereas the segmental extensors, primarily the multifidus muscle, provide stabilization of individual lumbar motion segments.

Where is the Iliocostalis Lumborum?

Iliocostalis is a dorsal muscle situated deep to the fleshy section of serratus anterior. Iliocostalis lumborum is the lower (lumbar) portion of that muscle.

Which muscle takes origin from the Sacrotuberous ligament and erector spinae aponeurosis?

Iliocostalis lumborum

It originates from the common origin of the erector spinae muscles, which includes the following: Spinous processes and supraspinous ligament of T11 through L5 (supraspinous ligament ends between L2 and L4) Median sacral crest. Sacrotuberous ligament.

What is the back muscle called?

Latissimus dorsi (lats), which helps you extend and rotate your shoulder and arm. Levator scapulae, which raises your scapula (shoulder blade). Rhomboids, two muscles (the rhomboid major and minor) that work together to pull the scapula inward toward the spine.

Where is the Semispinalis?

The semispinalis muscle is a type of transversospinalis muscle found in the human body. The transversospinalis muscle group is a very deep layer of muscles located on either side of the spine. The semispinalis muscle is the most superficial layer of this muscle group.

What are Erectors?

The erector spinae muscles are a group of muscles that belong to an even broader group of muscles called the paraspinal muscles. ... The erector spinae muscles include three main muscles which themselves can also be divided into sections. The erector spinae muscles include: iliocostalis, longissimus, and spinalis.

What are the 3 primary divisions of the erector spinae?

The erector spinae are divided into three groups, from medial to lateral: Spinalis muscles. Longissimus muscles. Iliocostalis muscles.

What Innervates Interspinales?

The interspinales muscles are innervated by the medial branches of the posterior primary divisions of spinal nerves. The interspinales muscles function to extend the spine and may act as proprioceptive organs (Bogduk, 2005).

Does Iliocostalis Lumborum move the spine?

Action. Stabilization of Spine: Iliocostalis lumborum along with multifidus contribute to support and control the orientation of lumbar spine.

What is the core muscle called?

The "core muscles," which are the muscles responsible for giving us strength and stability when bending or twisting, can essentially be broken down into seven different sets: the rectus abdominis, the external obliques, the internal obliques, the transversus abdominis, the multifidus, the quadratus lumborum and the ...

What are spinal extensors?

Extensor muscles. Attached to the back of the spine, these muscles allow us to stand and lift objects. They include the large muscles in the lower back (erector spinae), which help hold up the spine, and gluteal muscles.

How did multifidus get its name?

The name multifidus comes from two Latin words. “Multi” means many. And, “fidere” means to cleave or split into parts. From that you could get a muscle that is split into many parts.

What is Multifidi?

Anatomical terms of muscle

The multifidus (multifidus spinae : pl. multifidi ) muscle consists of a number of fleshy and tendinous fasciculi, which fill up the groove on either side of the spinous processes of the vertebrae, from the sacrum to the axis.

How do you cure erector spinae?

Stretching and strengthening these muscles will help them heal from a strain. Specific stretches that can be performed are pulling both knees to the chest while lying on the back, arching the back while on hands and knees, and then letting the back slump while on hands and knees.
