What is the function of the erector spinae?

Asked by: Amanda Barlow

The erector spinae muscles lie on each side of the vertebral column and extend alongside the lumbar, thoracic, and cervical sections of the spine. The erector spinae muscles function to straighten the back and provide for side-to-side rotation. An injury or strain to these muscles may cause back spasms and pain.

What is the function of the erector spinae quizlet?

The erector spinae muscles collectively are used to maintain posture and to stand erect.

What is the movement of the erector spinae?

Definition. 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.

What are the two actions of the erector spinae muscles?

The two major functions of the erector spinae muscle group are to extend and laterally flex the spine.

What are the erector spinae muscles What is its origin and insertion?

Since the erector spinae consist of nine separate muscles, there are many points of origin and insertion. In general, these muscles originate from the lumbar and lower thoracic regions of the body, and they insert onto the upper thoracic and cervical regions of the body.

What muscle extends and rotates the spine?

The multifidus muscles extend and rotate the vertebral column. Moving medially, we can see the multifidus muscles that originate on the sacrum and vertebrae and insert on more superior vertebrae. Due to these attachments, they extend and rotate the vertebral column.

What are the attachments of the erector spinae group quizlet?

Sacrum, spinous processes of lumbar and lower two thoracic vertebrae and their supraspinous ligaments, and the iliac crest. Angles of the lower six or seven ribs. Transverse processes of all thoracic vertebrae and just lateral to the tubercles of the lower nine or ten ribs.

What type of muscle is 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.

How do you activate erector spinae?

Right there rotate that upwards as much as possible keep rotating until you feel your lower erectors firing. Now touch the point of your sternum. Right here in the front.

Is erector spinae a core muscle?

Core Muscle Group: Erector Spinae



These core muscles, aka the back extensors, allow you to extend your trunk, such as rolling up from a forward fold or bending backward into a bridge, according to ACE. One side of the erector spinae also works with the obliques and rectus abdominis to allow for lateral trunk flexion.

What are the 4 major core muscles?

The global movers/muscles include: Rectus abdominis. External obliques. Erector spinae.

How can I strengthen my erector muscles?

The superman trains the erector spinae as an extensor by having you lift your legs and arms off of the ground by flexing your lower back and then holding this position. Your lower back will have to work to initiate the movement and stabilize to hold the top position isometrically.

What causes tight erector spinae?

The most common causes for these symptoms are inflammation, muscle strain, and muscle tear. Additionally, these muscles become tight if you live a sedentary lifestyle and your spinae erector muscles do the work to make up for weak abs, lats, and glutes.

How do you release tension from erector spinae?

Starting off in this position here three-point stance neutral pelvis we're going to tension up. We're going to drop our ass back to the heels holding that tension.

How do you stretch erector spinae?

Right between your legs. All the way down tuck your chin down to your chest. And similar thing just take some deep breaths in. And on the exhalation.

Why do my spinal erectors hurt?

An Erector spinae injury occurs when the muscles and connective tissues of the lower back become overused or stretched beyond their normal range of movement. Erector spinae pain can occasionally occur at the time of the injury, whilst playing a sport, perhaps a slip or trip.

What does a strained erector spinae feel like?

Symptoms of a strain or sprain include: Pain that gets worse when you move. Muscle cramping or spasms (sudden uncontrollable muscle contractions) Decreased function and/or range of motion of the joint (difficulty walking, bending forward or sideways, or standing straight)

How do I know if my back pain is muscle or spine?

If the pain you feel extends to your arms, forearms, and hands, the source may be your cervical spine. On the other hand, if you feel the pain radiating to your legs, it may be a problem with the lumbar spine.
