Nutrition
for the Latissimus Dorsi?
- Organ:* Pancreas
- Meridian:* Spleen
- NL Anterior:* 7th Intercostal space on the left at rib cartilage junction
- NL Posterior:* between T7-T8 at lamina on the left
- NV:* posterior to external auditory meatus superior to temporal suture
- Nutrition:* Vitsmin A, Vitamin F, Betaine HCl, pancreas protomorphogen, zinc, liver chelate, trace minerals, B12, selenium
What is the Origin and Insertion of the
Latissimus Dorsi?
Origin: arises from the crest of the olium, the scarum, the lumbar vertebrae and the lower six thoracic vertebrae. It also arises from the last 3 or 4 ribs.
Insertion: along with the fibres of the teres major and the pectoralis into the intertubercular groove of the humerus.
What is the Action of the Latissimus Dorsi?
Depresses the shoulder and extends the humerus.
Contraction of the latissimus will also adduct and aid in internal rotation of the humerus.
The upper fibres of the muscle will retract the scapula.
Bilateral contraction of the muscle causes extension of the thoracic spine.
What is the nerve supply of the Latissimus Dorsi?
ThoracoDorsal Nerve from Brachial Plexus
C6, C7 & C8
Synergists to the Latissimus Dorsi are?
Humerus Adduction: teres major, long head of triceps.
Scapula Depression: lower trapezius, abdominal external oblique.
Antagonists to the Latissimus Dorsi are?
Humerus Adduction: supraspinatus, deltoids.
Scapula Depression: upper trapezius, levator scapulae.
What are the signs of Inhibition of the
Latissimus Dorsi?
In standing posture, the shoulder will appear to be elevated and rotated anterior on the side of weakness
Bilateral weakness will contribute to an increased kyphotic curve of the thoracic spine.

Nutrition
for the Piriformis?
- Organ:* Reproductive Organs
- Meridian:* Circulation Sex
- NL Anterior:* Upper Symphasis Pubis
- NL Posterior:* Between L5 spinous and PSIS
- NV:* Posterior Parietal Eminence
- Nutrition:* Vitamin E, male/female organ;gland concentrate or nucleoprotein extract, saw palmetto
What is the Origin and Insertion of the Piriformis?
Origin: Arises from the anterior surface of the sacrum from between the first and second sacral foramina to between the third and fourth sacral foramina, the sacroiliac joint capsule and the sacrospinous ligament.
Insertion: Inserts into the medial, superior surface of the greater trochanter of the femur.
What is the Action of the Piriformis?
Controls pelvic rotation on heel strike and during the initial stages of stance.
It aids in stabilizing the femur head in the acetabulum.
It functions as a lateral rotator of the femur when the femur is flexed less than 90 degrees.
Above 90 degrees, the muscle changes to a medial rotator. The lower fibers cause anterior movement of the ipsilat-eral sacral base and posterior motion of the sacral apex.
What is the Nerve supply of the Piriformis?
Sacral Plexus
L5, S1 and S2
Synergists to the Piriformis are?
Thigh Lateral Rotation: Gluteus maximus, long head of the Biceps femoris, posterior fibers of the gluteus medius, sartorius and psoas.
Sacroiliac Stability:Gluteus Maximus
Antagonists to the Piriformis are?
Thigh Lateral Rotation: Semimembranosus, semitendinosus, Tensor fascia lata,
pectineus, anterior fibers of the gluteus medius, adductor longus and adductor medius.
What are the signs of inhibition of the Piriformis?
Medial rotation of the femur, this is especially evident when observing the patient walking. The patella will be rotated during the swing phase of gait. Depending on the function of other thigh rotators this same rotation will be present in the standing posture.

What is the Origin and Insertion of the Teres Minor?
Origin: Arises from the medial one third of the axillary border of the scapula on the dorsal surface.
Insertion: Into the most inferior aspect of the greater tuberosity of the humerus.
What is the Action of the Teres Minor?
Contraction of the Teres Minor causes external rotation of the humerus in the glenoid cavity.
The muscle also aids in the stabilization of the head of the humerus in the glenoid cavity. In this regard, the muscle contracts throughout the stages of arm.
What is the Nerve supply of the Teres Minor?
Axillary Nerve
C4, C5, C6
