Erector Spinae

The Erector Spinae Muscles work together to keep the spine erect as well as assist in bending sidewards motions and assisting the extensionthe action of moving a limb from a bent to a straight position of the Neck and face to turn

The Erector Spinae muscle actually consists of three columns of muscles, the Iliocostalis, Longissimus, and Spinalis, each  running parallel on either outer side of the Thoracicthe part of the body of a mammal between the neck and the abdomen, including the cavity enclosed by the ribs, breastbone, and dorsalof, on, or relating to the upper side or back of an animal, plant, or organ vertebrae, and containing the chief organs of circulation and respiration; the chest. Vertebraeach of the series of small bones forming the backbone, having several projections for articulation and muscle attachment, and a hole through which the spinal cord passes and extending from the lower back of the skull all the way down to the Pelvis. The Erector Spinae provides resistance that assists in the control action of bending forward at the waist as well as acting as powerful extensorsthe action of moving a limb from a bent to a straight position to promote the return of the back to the erect position. During full flexiona. The act of bending a joint or limb in the body by the action of flexorsa. The act of bending a joint or limb in the body by the action of flexors. b.

(i.e., when touching fingertips to floor), the Erector Spinae Muscles are relaxed and strain is borne entirely by ligaments of back, however on the reversal of the movement, the Erector Spinae in conjunction with the  Hamstring muscles and Gluteus Maximus muscles (buttockseither of the two round fleshy parts that form the lower rear area of a human trunk) is primarily responsible for the extensionthe action of moving a limb from a bent to a straight position of the back (straighten the spine) as well as more specific movements such as the extensionthe action of moving a limb from a bent to a straight position of the neck Vertebraeeach of the series of small bones forming the backbone, having several projections for articulation and muscle attachment, and a hole through which the spinal cord passes and sidewards movement of the headthe end of a muscle at the site of its attachment (originthe source or beginning of anything, especially the more fixed end or attachment of a muscle) to a bone or other fixed structure..

Muscles that make up the Erector Spinae

ILIOCOSTAL MUSCLES

Vertebraeach of the series of small bones forming the backbone, having several projections for articulation and muscle attachment, and a hole through which the spinal cord passes of all the Erector Spinae muscles the Iliocostalis muscle is chiefly responsible with assisting extensionthe action of moving a limb from a bent to a straight position and laterally flex of the vertebral column, maintaining erect posture as well as bending the vertebral column to the same side.  The Iliocostalis Muscles originthe source or beginning of anything, especially the more fixed end or attachment of a muscle attachment point is the Lumbosacral Fasciaa thin sheath of fibrous tissue enclosing a muscle or other organtendinous mass covering the sacruma triangular bone in the lower back formed from fused vertebraeeach of the series of small bones forming the backbone, having several projections for articulation and muscle attachment, and a hole through which the spinal cord passes and situated between the two hipbones of the pelvis, the inferiorlow or lower in 6 ribs (thoracis) and ribs 3 to 6 (cervicis). The insertionthe source or beginning of anything, especially the more fixed end or attachment of a muscle attachment points are the  angles of ribs 7 to 12 (lumborum and thoracis); transversesituated or extending across something processes of cervicalof or relating to the neck vertebraeeach of the series of small bones forming the backbone, having several projections for articulation and muscle attachment, and a hole through which the spinal cord passes C6–C4 (cervicis).

The Iliocostalis Muscle is one of three muscles which make up the Erector Spinae Muscles

THE LONGISSIMUS DORSI MUSCLES

The Longissimus Dorsi Muscle  the longest of the back and is made up of 3 distinct parts, the Capitis, the Cervicis and the Thoracis.

1.  The Capitis Muscles are used to hold the headthe end of a muscle at the site of its attachment (originthe source or beginning of anything, especially the more fixed end or attachment of a muscle) to a bone or other fixed structure. erect as well as rotating toward the same side of the muscle that is contracting.

The Longissimus Dorsi Muscle is considered to be one of the longest muscles in the human body.

THE SPINALIS MUSCLES

The Spinalis muscles are the closest to the thoracicthe part of the body of a mammal between the neck and the abdomen, including the cavity enclosed by the ribs, breastbone, and dorsalof, on, or relating to the upper side or back of an animal, plant, or organ vertebrae, and containing the chief organs of circulation and respiration; the chest. Vertebraeach of the series of small bones forming the backbone, having several projections for articulation and muscle attachment, and a hole through which the spinal cord passes of all the Erector Spinae muscles and consists of two muscles, the Cervicis and the Thoracis.

1. The Spinalis Cervicis originthe source or beginning of anything, especially the more fixed end or attachment of a muscle points are from the lower ligamentum nuchaefiborous membrane in the neck: spinous processes of C6 or C7 and the insertionthe source or beginning of anything, especially the more fixed end or attachment of a muscle point of attachment is the spinous process of the axis. The Spinalis Cervicis Muscles work closely with the Spinalis Thoracis muscle to extend and laterally flex vertebral column such as when you try to stand tall to increase your height by extending the gap between your vertebraeeach of the series of small bones forming the backbone, having several projections for articulation and muscle attachment, and a hole through which the spinal cord passes.
2. The Spinalis Thoracis originthe source or beginning of anything, especially the more fixed end or attachment of a muscle points are from the inner portion of the Lumbosacral Fasciaa thin sheath of fibrous tissue enclosing a muscle or other organtendinous mass covering the sacruma triangular bone in the lower back formed from fused vertebraeeach of the series of small bones forming the backbone, having several projections for articulation and muscle attachment, and a hole through which the spinal cord passes and situated between the two hipbones of the pelvis as well as from the spinous processes of T11 to L2. It’s insertionthe source or beginning of anything, especially the more fixed end or attachment of a muscle points are most if not all of the spinous processes of the upper thoracicthe part of the body of a mammal between the neck and the abdomen, including the cavity enclosed by the ribs, breastbone, and dorsalof, on, or relating to the upper side or back of an animal, plant, or organ vertebrae, and containing the chief organs of circulation and respiration; the chest. vertebraeeach of the series of small bones forming the backbone, having several projections for articulation and muscle attachment, and a hole through which the spinal cord passes from T2 to T8.
