Some Pilates Anatomy
Pilates works with a stabilization and a mobilization systems.(deep muscles closest to the skeletal and respiratory system)
For Pain management one should generally learn to stabilize before mobility is involved
Primarily Responsible for the stability of the lumbar-pelvic-hip complex muscles( the hip flexors) , shoulder girdle, neck and around the muscles closest to respiratory system.
Pilates works with deep muscles ( the muscles closest to the bone structure.)
Muscles and muscle systems that make up the stabilization- mobilization include but are not limmited to;
· Transverse Abdominus
· Lumbar Multifidus
· Transverse Spinalis
· Serratus /Intercostal/Diaphragm
· Rectus Abdominus
· Pelvic Floor Muscles
· Latissimus Dorsi/Rhomboids/all musceles around the shoulder girdle
· Erector Spinae
· Hamstrings Complex
· Hip Adductor Complex / Hip Abductor Complex
Transverse Abdominus
The transversus abdominis, so called for the direction of its fibers, is the innermost of the flat muscles of the abdomen, being placed immediately beneath the internal oblique muscle.
It arises, as fleshy fibers, from the lateral third of the inguinal ligament, from the anterior three-fourths of the inner lip of the iliac crest, from the inner surfaces of the cartilages of the lower six ribs, interdigitating with the diaphragm, and from the lumbodorsal fascia.
The muscle ends anteriorly in a broad aponeurosis, the lower fibers of which curve inferomedially (medially and downward), and are inserted, together with those of the internal oblique muscle, into the crest of the pubis and pectineal line, forming the inguinal aponeurotic falx, also called the conjoint tendon. In layperson’s terminology, the muscle ends in the middle line of a person’s abdomen.
Throughout the rest of its extent the aponeurosis passes horizontally to the middle line, and is inserted into the linea alba; its upper three-fourths lie behind the rectus muscle and blend with the posterior lamella of the aponeurosis of the internal oblique; its lower fourth is in front of the rectus abdominis.
Lumbar Multifidus
The multifidus (multifidus spinae : pl. multifidi ) muscle consists of a number of fleshy and tendinous fasciculi, which fill up the groove on either side of the spinous processes of the vertebrae, from the sacrum to the axis. The multifidus is a very thin muscle.
Deep in the spine, it spans three joint segments, and works to stabilize the joints at each segmental level.
The stiffness and stability makes each vertebra work more effectively, and reduces the degeneration of the joint structures.
These fasciculi arise:
    • in the cervical region: from the articular processes of the lower four vertebrae.
Each fasciculus, passing obliquely upward and medialward, is inserted into the whole length of the spinous process of one of the vertebræ above.
These fasciculi vary in length: the most superficial, the longest, pass from one vertebra to the third or fourth above; those next in order run from one vertebra to the second or third above; while the deepest connect two contiguous vertebrae.
Transverse Spinalis
Its fibers run perpendicular to the external oblique muscle, beginning in the thoracolumbar fascia of the lower back, the anterior 2/3 of the iliac crest (upper part of hip bone) and the lateral half of the inguinal ligament. The muscle fibers run from these point superiomedially (up and towards midline) to the muscle’s insertions on the inferior borders of the 10th through 12th ribs and the linea alba (abdominal midline seam).
The internal oblique is innervated by the lower intercostal nerves, as well as the iliohypogastric nerve and the ilioinguinal nerve.
The internal oblique performs two major functions. First, it acts as an antagonist (opponent) to the diaphragm, helping to reduce the volume of the thoracic (chest) cavity during exhalation. When the diaphragm contracts, it pulls the lower wall of the chest cavity down, increasing the volume of the lungs which then fill with air. Conversely, when the internal obliques contract they compress the organs of the abdomen, pushing them up into the diaphragm which intrudes back into the chest cavity reducing the volume of the air filled lungs, producing an exhalation.
Secondly, its contraction rotates and side-bends the trunk by pulling the rib cage and midline towards the hip and lower back, of the same side. It acts with the external oblique muscle of the opposite side to achieve this torsional movement of the trunk. For example, the right internal oblique and the left external oblique contract as the torso flexes and rotates to bring the left shoulder towards the right hip. For this reason, the internal obliques are referred to as “same side rotators.”
Rectus Abdominus
The rectus abdominis is an important postural muscle. It is responsible for flexing the lumbar spine, as when doing a “crunch“. The rib cage is brought up to where the pelvis is when the pelvis is fixed, or the pelvis can be brought towards the rib cage (posterior pelvic tilt) when the rib cage is fixed, such as in a leg-hip raise. The two can also be brought together simultaneously when neither is fixed in space.
The rectus abdominis assists with breathing and plays an important role in respiration in the event the patient is short of breath.[clarification needed] It also helps in keeping the internal organs intact and in creating intra-abdominal pressure, such as when exercising or lifting heavy weights, during forceful defecation or parturition (childbirth).
Blood supply
The rectus abdominis has several sources of arterial blood supply. In reconstructive surgery terms, it is a Mathes and Nahai[1] Type III muscle with 2 dominant pedicles. First, the inferior epigastric artery and vein (or veins) run superiorly on the posterior surface of the rectus abdominis, enter the rectus fascia at the arcuate line, and serve the lower part of the muscle. Second, the superior epigastric artery, a terminal branch of the internal thoracic artery, supplies blood to the upper portion. Finally, numerous small segmental contributions come from the lower six intercostal arteries as well.
The muscles are innervated by thoracoabdominal nerves, which pierce the anterior layer of the rectus sheath.
The rectus abdominis is a long flat muscle, which extends along the whole length of the front of the abdomen, and is separated from its fellow of the opposite side by the linea alba. The muscle is inserted by three portions of unequal size into the cartilages of the fifth, sixth, and seventh ribs. The upper portion, attached principally to the cartilage of the fifth rib, usually has some fibers of insertion into the anterior extremity of the rib itself.
Some fibers are occasionally connected with the costoxiphoid ligaments, and the side of the xiphoid process.
Pelvic Floor Muscles
The pelvic floor or pelvic diaphragm is composed of muscle fibers of the levator ani, the coccygeus, and associated connective tissue which span the area underneath the pelvis. The pelvic diaphragm is a muscular partition formed by the levatores ani and coccygei, with which may be included the parietal pelvic fascia on their upper and lower aspects. The pelvic floor separates the pelvic cavity above from the perineal region (including perineum) below.
The right and left levator ani lie almost horizontally in the floor of the pelvis, separated by a narrow gap that transmits the urethra, vagina, and anal canal. The levator ani is usually considered in three parts: pubococcygeus, puborectalis, and iliococcygeus. The pubococcygeus, the main part of the levator, runs backward from the body of the pubis toward the coccyx and may be damaged during parturition. Some fibers are inserted into the prostate, urethra, and vagina. The right and left puborectalis unite behind the anorectal junction to form a muscular sling . Some regard them as a part of the sphincter ani externus. The iliococcygeus, the most posterior part of the levator ani, is often poorly developed.
The coccygeus, situated behind the levator ani and frequently tendinous as much as muscular, extends from the ischial spine to the lateral margin of the sacrum and coccyx.
The pelvic cavity of the true pelvis has the pelvic floor as its inferior border (and the pelvic brim as its superior border.) The perineum has the pelvic floor as its superior border.
Some sources do not consider “pelvic floor” and “pelvic diaphragm” to be identical, with the “diaphragm” consisting of only the levator ani and coccygeus, while the “floor” also includes the perineal membrane and deep perineal pouch.[2] However, other sources include the fascia as part of the diaphragm.[3] In practice, the two terms are often used interchangeably.
Posteriorly, the pelvic floor extends into the anal triangle.
3)Movement System
v Responsible for movement of the core
4) Muscles that make up the movement system
Latissimus Dorsi
into the anterior extremity of t he rib itself.
Some fibers are occasionally connected with the costoxiphoid ligaments, and the side of the xiphoid process.
Erector Spinae
Illio Psoas Complex
the hip flexors are a group of skeletal muscles that act to flex the femur (thigh bone) onto the lumbo-pelvic complex, i.e., pull the knee upward.
The hip flexors are (in descending order of importance to the action of flexing the hip joint):[1]
  • · Hamstrings   Complex
  • Hip Adductor Complex / Hip Abductor Complex
