What happens when the erector spinae contract concentrically?
Contraction of the erector spinae muscles can produce either unilateral flexion of the spine, or when they are used bilaterally they produce extension of the spine, which is more properly called the vertebral column.
What is the quadratus lumborum?
It has two separate actions, depending on whether both or only one is contracted. Unilateral (only one muscle) contraction gives rise to lateral flexion of the back/vertebral column. Bilateral (both sides) contractions causes depression of the thoracic rib cage (usually during respiration).

What is the name of an intended action of the primary muscle for the abdominal?
Trunk flexion & unilateral trunk flexion.
What is the vertebral movement?
Forward bending or flexion, backward bending or extension. Side to side bending or lateral flexion and rotation.
What is a contraction in which the muscle shorten and work is done?
This is muscle flexion or isotonic contraction.
What muscle does the lateral flexion of the torso involve?
Primarily quadratus lumborum, unilateral contraction of spinalis muscles (you can feel these contract in your lower-mid back on the side to which you're bending against resistance) and, to a lesser extent, oblique muscles.
What movement does contraction of the brachialis produce?
flexion of elbow
What muscle is located on the sides of the vertebral column?
Erector spinae are the muscles that move the vertebral column.It is the largest muscle mass of the back, forming a prominent bulge on either side of the vertebral column.It is the chief extensor of the vertebral column. It is also important in controlling flexion, lateral flexion and rotation of the vertebral column and in maintaining the lumbar curve, because the main mass of the muslce is in the lumbar region.Consists of: iliocostalis, longissimus and spinalis.Erector spinae are the muscles that move the vertebral column.
When your muscles shorten this is called what?
This is due to contraction of the biceps, and is known as flexion.
