MTB 113
The posterior scalene inserts here.
The Second Rib.
"Play my PS2 till 1AM."
These intercostals depress the ribcage to magnify exhalation.
The Internal Intercostals.
"INternals cause EXhalation. EXternals cause INhalation."
These two groups of muscles make up the larger paraspinal muscle group.
The Transversospinalis and the Erector Spinae.
You know you have reached the deepest layer of the transversospinalis muscle group when you reach these muscles.
The Rotatores.
*I love spaghetti with RED MEAT SAUCE.*
(Deep to Superficial)
Your book lists this as the "hip hike" muscle.
Quadratus Lumborum.
Quadratus = square shaped
Lumborum = Lumbar.
This is the origin of Serratus Posterior Inferior.
The Spinous Processes of T11 - L2.
"Sera Posts on Instagram, Several Processes from 11:00 pm till 2:00 am."
The rectus sheath covers these four muscles.
The Rectus Abdominis, The Obliques, and the Transverse Abdominis.
These groups of muscles combine to form the erector spinae group.
The Illiocostalis, The Longissimus, and the Spinalis.
*I LOVE SPAGHETTI with red meat sauce.*
(Lateral to Medial.)
Your book lists this as the "six pack" muscle.
Rectus Abdominis.
This is the insertion of the Serratus Posterior Inferior.
Ribs 9 - 12.
"Serra Posts on Instagram, all-you-can-eat Ribs from 9:00 am - 12:00 pm."
This is the most superficial muscle of the transversospinalis group.
The Semispinalis.
*I love spaghetti with RED MEAT SAUCE.*
(Deep to Superficial)
Call on this "Sarah", along with the intercostals, to depress the ribcage during exhalation.
The Serratus Posterior Inferior.
This muscle's appearance is unique because it includes tendinous intersections throughout the muscle belly.
The Rectus Abdominis.
These intercostals perform elevation of the ribcage to maximize space during inhalation.
The External Intercostals.
"Externals INhale. INternals EXhale."
This is the intermediate muscle in the transversospinalis muscle group.
The Multifidus.
*I love spaghetti with RED MEAT SAUCE.*
(Deep to Superficial)
The abdominal diaphragm performs these two functions during inhalation. One in the chest cavity. The other in the abdominal cavity.
Increase Thoracic Cavity Volume and Increase Intraabdominal Pressure.
The "white line" between the left and right rectus abdominis muscles.
Linea Alba.
The diaphragm muscle inserts at this tendon.
The Central Tendon.
The obliques perform this action, regardless of how deep they live.
Rotation of the Vertebral Column.
Rotation of the Trunk.
This is the primary muscle of inhalation in the body.
The Diaphragm.
The Suboccipitials.
Sub = Deep / Beneath
Occipital = Most Posterior Cranial Bone.
The most medial muscle group of the erector spinae muscle group.
The Spinalis.
*I LOVE SPAGHETTI with red meat sauce.*
(Lateral to Medial.)
These muscle groups make up the transversospinalis group of the back.
The Rotatores, The Multifidus, and The Semispinalis.
*I love spaghetti with RED MEAT SAUCE.*
(Deep to Superficial)
When their powers combine, the erector spinae group perform this action.
Extension of the Vertebral Column.
This is the origin of the quadratus lumborum muscle.
The Posterior Illiac Crest.
Quadratus = square shaped
Lumborum = Lumbar.
