Revision of yesterday
Tailbone is sacrum and coccyx

The movements
The bones- T7 base of scapula. L3/ L4 is where hips are,
Joints- SC joint is the sternum clavicle joint, sternum that joins the ribs is cartilage. 8
carpal bones. Elbow is a hinge joint – synovial, between radius and ulna is pivot joint,
shoulder is ball and socket joint (synovial joint) patella embedded in tendon, lower leg
fibula on the outside, tarsal bones before metatarsals.
Muscles and tendons
Respiration and back muscles levator scapulae lifts shoulder blade
SCM sternocleidomastoid from anterior thoracic muscle.
Homeostasis body in balance
Anterior thorax and abdominal wall
Pectoralis
Deltoid attaches to humor bone on the deltoid promiris
Rectus abdominus – not for core stability
Stabilizing Muscles are: External obliques on top, then internal obliques, Transverse abdominuslike a corset or a belt
These stabilizing muscles work with little muscle in the spine
Rotatores are the back tiny muscles between vertebrae and rotate the segments
Concept of core







External oblique
Internal oblique
Transverse abdominus
Psoas
Diaphragm
Pelvic floor
All these help stabilize the pelvis.
Jennifer Wathall Yoga TT 2009
Throat muscle is sternocleidomastoid SCM
Pectoralis allows shoulder blade to glide up and forwards and adduct and abduct from body
Psoas number 12 psoas minor amd 13 psoas major near lumbar thin muscle attaches on inside
of hip in the groin. Flexion of hip and stabilizes core. Very important in pregnancy helps track
baby goes through the pelvic rim.
Number 14 iliacus
Ilio psoas tendon is 12,13,14. ALL 5 LUMBARS ATTACHED TO PSOAS
It goes inside of hip bone attaches on the proximal part of the medial aspect of the femur.
Number 4 on the diaphragm and psoas is continuous in terms of fascia.
Number 11 is quadratus lumborum QL not part of the core stability. It allows side bending 2-D
movement
Psoas is responsible for…
Diaphragm is the pump of life. Correct way to breathe move the diaphragm in and out to
massage organs- pumping action suck up lumph and pump around the system.
Movement : Arteries, veins, Lymph
Lymph is your immune system, drops off toxins. Lymph is fluid retention
Lymph and fascia and cerebral fluid is send act as one
Summary so far
Diaphragm is respiration, allows for lymph and digestion etc
Good core stability - obliques and TA, good diaphragm, psoas, rotators and pelvic floor.
Diaphragm refer to diagram
Pelvic floor – need to stabilize this.
Levator ani is a muscle elevates the anus – like a sling sphincter contract and relax rectum.
Works with TA and psoas, diaphragm, etc.
Review of muscles
Trapezius,
Deltoid
Jennifer Wathall Yoga TT 2009
Obliques internal external
Lattisismus dorsi used to is adductor and internal rotator of shoulder attaches to trapezius
Gluteus
ITB fascia down to knee
Limbs

Shoulder girdle
Made of three bones clavicle, scapula and humorous.
Supraspinatus muscle sits on top of scapula causes rotator cuff problems- tears easily.
Bursa gets inflamed as well- prevents friction of muscle and bone. Bursa can inflame and
leak!
The lady lies between the majors
Pectoralis major
Lattisimus dorsi
Terres major – muscle inside of humorous
These three help internal rotation
Shoulder has got muscles to internal, external rotation. External rotation are rotator
cuffs- the muscles are supraspinatus, infraspinatus, terres minor .
Rotator cuff has 4 muscles- 3 external one internal.
Supraspinatus, infraspinatnus and terres minor externally rotate the shoulder.



Subscapularis only rotator cuff which internally rotates the shoulder
Shoulder blade
Supra on top
Sub under
Infra
Name bones in shoulder girdle
Name all 4 rotator cuffs and their action
Name 6 major muscles responsible for activating the core TA, External. Internal
obliques, levator ani, psoas, diaphragm
Yes or no –Are scalene muscles are they primary muscles of respiration?
They are Accessory muscles
All movements of the spine – what happens in C, T and L sections- primary movements?
Cervical spine is the most mobile- rotation
Thoracic spine = side bending/ rotation
Lumbars = flexion/ extension
