What 3 group of muscles make up the erector spinae?
Longissimus Thoracis – Physiopedia Description longissimus thoracis The longissimus muscle is a long intrinsic muscle of the back. Along with spinalis and iliocostalis, these three muscles comprise the erector spinae group.
Which muscles are in the Transversospinalis group?
The deep layer contains the transversospinalis muscle group which is made up of the semispinalis, multifidus, and rotatores muscles. These muscles lie between the spinous and transverse processes of the vertebral column, deep to the erector spinae muscles.
Where are the transversospinalis muscles located relative to the erector spinae group?
Transversospinales muscle group is a deep group of back muscles that lies deep to the Erector Spinae. It consists of 3 major subgroups: semispinalis, multifidus and rotatores.
Where are the erector spinae?
The erector spinae muscles are a group of long muscles that originate near the sacrum and extend vertically up the length of the back. The erector spinae muscles lie on each side of the vertebral column and extend alongside the lumbar, thoracic, and cervical sections of the spine.
Where is the erector spinae group?
spine
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.
Which of the following is not a group of the erector spinae muscles?
Which of the following is not a part of the erector spinae muscle group? Explanation: The main muscle groups that make up the erector spinae are the iliocostalis muscles, the longissimus muscles, and the spinalis. The trapezius is not a part of the erector spinae group.

back
The erector spinae muscles are a group of long muscles that originate near the sacrum and extend vertically up the length of the back. The erector spinae muscles lie on each side of the vertebral column and extend alongside the lumbar, thoracic, and cervical sections of the spine.
Which are Infrahyoid muscles?
The four infrahyoid muscles are the sternohyoid, omohyoid, sternothyroid, and thyrohyoid muscles.
What are Infrahyoid group of muscles?
Infrahyoid muscles are also known as “strap muscles” which connect hyoid, sternum, clavicle and scapula. They are located below the hyoid bone on the anterolateral surface of the thyroid gland and are involved in movements of the hyoid bone and thyroid cartilage during vocalization, swallowing and mastication.
What are the erector spinae muscles?
The erector spinae muscles are nine different muscles located at the back that allows various movements from stretching to aerobic back-bends. These nine muscles are divided into three different groups: iliocostalis, longissimus, and spinalis. The erector spinae muscles are often called spinal erectors.
Which posture causes the erector spinae to contract?
Poses where the erector spinae muscles contract: Postures such as shalabhasana will cause all of the erector spinae muscles to contract and lift the spine into hyperextension. In urdhva dhanurasana, we use the erector spinae muscles to concentrically contract against the resistance of both gravity and the front of the body.

What fascia covers the erector spinae?
Erector spinae are covered by the thoracolumbar fascia in the thoracic and lumbar regions. They lie deep to the serratus posterior inferiorly and rhomboids and splenius muscles superiorly. The erector spinae group is the main extensor of the vertebral column.
