The Axial and Appendicular Skeleton

Appendicular SkeletonSkeleton Yoga

The axial skeleton consists of the spinal column, cranium (skull), and rib cage. The spinal column surrounds and protects the spinal cord, which is the central energy channel, or sushumna nadi. Itis the axis around which the poses of yoga revolve. The appendicular skeleton connects us with the world. The lower extremities form our connection to the earth. The upper extremities, in association with our senses, connect us with each other.

The Shoulder Girdle

The shoulder girdle is the yoke that connects the upper extremities with the axial skeleton. It is the seat of the brachial plexus, a collection of nerves that in association with the heart forms the basis for the fourth and fifth chakras. The shoulder girdle is comprised of the following structures:

• Scapula (shoulder blade)

• Scapulothoracicjoint

• Sternoclavicular and Acromioclavicular joints

• Glenohumeraljoint

The Pelvic Girdle

The pelvic girdle is the yoke that connects the lower extremities to the axial skeleton. It is the seat of the sacral plexus, a collection of nerves that forms the basis for the first and second chakras. The pelvic girdle is comprised of the following structures:

• Sacroiliacjoint

Connecting the Appendicular and Axial Skeleton

Eka pada viparita dandasana demonstrates connecting the upper and lower appendicular skeletons to create movement in the axial skeleton. Note the inset image demonstrating stimulation of the spinal nerves in this back bend.

The Vertebral Column cervical thoracic lumbar sacrum coccyx

We determine the spinal curves by viewing them from the side. Kyphosis is a convex curve and lordosis is a concave curve.

This illustration demonstrates the four normal curves in the spine:

1) cervical lordosis

2) thoracic kyphosis

3) lumbar lordosis

4) sacral kyphosis

Scoliosis

Cervical Scoliosis

When the magnitude of the scoliotic curve progresses beyond 20 degrees, there is a risk of continued progression after skeletal maturity. Very large scoliotic curves can impact respiration by restricting the ribcage.

Movement Muscles Scoliosis

When the magnitude of the scoliotic curve progresses beyond 20 degrees, there is a risk of continued progression after skeletal maturity. Very large scoliotic curves can impact respiration by restricting the ribcage.

Scoliosis also affects the pelvic and shoulder girdles, as illustrated here. For example, tilting the pelvic girdle creates a perception of limb length discrepancy (one leg shorter than the other). Similarly, one arm may appear shorter than the other.

Scoliosis affects the bone, cartilage and muscles of the spine. Muscles on the concave side of a curve become chronically shortened when compared with those on the convex side. Yoga postures aid to counteract this process by stretching the shortened muscles.

Scoliosis is a lateral deviation and rotational deformity of the spine. The most common form of scoliosis is called "idiopathic", meaning without an identifiable cause. Other forms include congenital and neuromuscular scoliosis. Studies have suggested that idiopathic scoliosis is related to hormonal factors including the level of melatonin produced. This form of scoliosis also has a hereditary component.
