8. The Superficial Back Arm Line

     The Superficial Back Arm Line is the fascial connection from spine to fingers.  It controls arm movements behind our lateral midline (ex. A backhand tennis shot) but, for the most part, limits and contains the work of the Superficial FRONT Arm Line.  The SBAL also maintains control during abduction (lifting away from the body's midline) of the shoulder and arm; this can cause the line to get overworked when the rib cage or spine moves out of alignment with the shoulder girdle.

Next week, I'll start The Functional Lines with The Back Functional Line.

 

Stretch, hydrate, breathe deeply, and as always -

Be good to yourselves. <3

 

7. The Deep Back Arm Line

    

     The Deep Back Arm Line is similar to the Lateral Line in the leg.  It works with the Deep Front Arm Line to adjust the angle of the elbow, as well as limit or allow side-to-side movement of the upper body when in a crawl position, and provide stability from the lateral edge of the hand to the posterior shoulder.


Muscles of the DBAL:
Rhomboids
Rotator cuff muscles:
     Supraspinatus
     Infraspinatus
     Teres minor
     Subscapularis
Triceps brachii
Hypnothenar muscles:
     Abductor digiti minimi
     Flexor digiti minimi brevis
     Opponens digiti minimi

 

Connective tissues of the DBAL:
Fascia along ulnar periosteum
Ulnar collateral ligaments

Bony landmarks of the DBAL:Spinous process of lower cervical and thoracic vertebrae
C1-4 Transverse processes
Medial border of the scapula
Head of the humerus
Olecranon of the ulna
Triquetrum, hamate
Outside of the little finger

Stretches for the DBAL:

Tricep stretch

 

Ulnar nerve stretch

Take care of yourselves. <3

 

 

 

6. The Superficial Front Arm Line

     The Superficial Front Arm Line controls the positioning of the arm in its lateral and anterior movements.  The larger muscles of the SFAL (the pectoralis major and latissimus dorsi) aid in the force for addiction and extension, movements used in activities like swimming or tennis.  Through the fingers and wrists, the SFAL assists the DFAL in grip.

Muscles of the SFAL:
Pectorals major
Latissimus dorsi (not completely pictured below)
Flexor group

Connective tissue of the SFAL:
Medial intermuscular septum
Carpal tunnel

Bony landmarks of the SFAL:
Medial third of clavicle
Coastal cartilage
Lower ribs
Thoracolumbar fascia
Iliac crest
Medial humeral line
Medial humeral epicondyle
Palmar surface of the fingers

 

Common postural deviations associated with the SFAL:
Carpal tunnel impingement
Protracted or rounded shoulders
Finger/hand pain

Stretches for the SFAL:

 

This is a really good representation of how to properly do Downward Facing Dog.

Sorry I missed a week, guys; Austin's allergies had it in for me, but thanks to lots of sleep and NetiPot, I'm back online.  I hope you are well!

 

I'll be back next week with the Deep Back Arm Line.

 

Be good to yourselves. <3
