I. A Non-Judgmental Comparison of Yoga to Other Forms of Body Movement
A. Yoga and yoga-based movement -- Inner (intrinsic) movement
B. Exercise, sport and physical therapy -- Outer (extrinsic) movement
II. How Yoga Works
A. Law: Uniform or constant fact or principle
1. Davis Law: If muscle ends are brought closer together, the pull on tonus is increased, which shortens the muscle (may even cause hypertrophy); and if muscle ends are separated beyond normal, tonus is lessened or lost (thus the muscle becomes "weak"
2. Arndt-Schultz Law: Weak stimuli activate physiological processes; very strong stimuli inhibit them
3. Pflugers's Laws:
a. Law of Unilaterality: If a mild irritation be applied to one or more sensory nerves, the movement will take place usually on one side only, and that side which is irritated
b. Law of Symmetry: If the stimulation be sufficiently increased, motor reaction is manifested, not only by the irritated side, but also in similar muscles on the opposite side of the body
c. Law of Intensity: Reflex movements are usually more intense on the side of irritation; at times the movements of the opposite side equal them in intensity, but they are usually less pronounced
d. Law of Radiation: If the excitation continues to increase, it is propagated upward and reactions take place through centrifugal nerves coming up form the cord segments higher up
e. Law of Generalization: When the irritation becomes very intense, it is propagated in the medulla oblongata, which becomes a focus from which stimuli radiate to all parts of the cord, causing a general contraction of all muscles of the body
4. Law of Facilitation: When an impulse has passed once through a certain set of neurons to the exclusion of others, it will tend to take the same course on future occasions, and each time it traverses this path, the resistance will be smaller
5. Hilton's Law: A nerve trunk which supplies a joint also supplies the muscles of the joint and the skin over the insertions of such muscles (must also pass through fascia)
B. Application of Bachin Charts to yoga

Yoga Terminology
As a way of developing continuity across different yoga, exercise and medical platforms, it may be helpful to have an awareness of Kinesiology and Anatomical terminology. Accordingly, the following lists represent a basic vocabulary relevant to yoga.
Kinesiology and Anatomy of Yoga
Abduction
Movement of a body part away from center
Adduction
Movement of a body part toward center
Agonist
The muscle directly engaged in contraction as distinguished from antagonist
Antagonist
Muscles that have to relax to allow the Agonist to contract
Circumduction
Moves a part so its distal end describes a circle and the rest of the part describes a cone
Depression
The state of drawing the shoulder blades downward
Dorsiflexion
Drawing the foot upward toward the ankle
Elevation
The state of pulling the shoulder blades upward
Extension
A bending motion of a joint that lengthens its angle
Fibrillation
Abnormal muscle contraction where Individual fibers contract asynchronously
Flexion
A bending motion of a joint that shortens its angle
Hyperextension
To over straighten or bending motion of a joint that stretches beyond anatomical position
Isometric Contraction (Strengthen)
Where length remains constant but tension increases
Isotonic Contraction (Strengthen)
Contraction where tone or tension remains constant but muscle shortens (as in weight lifting)
Lateral
Refers to a body part further away from center than another body part
Medial
Refers to a body part closer to center than another body part
Plantarflexion
Moving the toes away from the ankle
PNF Stretching
Isometric contraction of antagonist muscle, then a stretching of the Agonist muscle
Pronation
Movement of the hand palm down
Proprioception
The awareness of posture, movement, and changes in weight and resistance in relation to the body
Protraction
The state of broadening or moving the shoulder blades outward
Proximal
Location of a body part toward center away from end
Relaxation
Stimulates production of neurotransmitters such as endorphins (inhibits pain conduction) and norepinephrine (involved in mood regulation as well as pleasure or reward emotions)
Relaxation Response
The ability to create relaxation at will. (The opposite of a willful neuromuscular action or response)
Retraction
The state of drawing the shoulder blades toward center
ROM
Range of Movement
Stretch:
Elongates muscle tissue matrix
Supinate
Movement of the hand palm up-- Subtly opens chest during supine breath management and relaxation
Tonus
Partial contraction in relays — important for maintaining proper posture:
Flaccidity=weak tonus
Spasticity=Overactive tonus
Anatomy of Yoga - 7th Cervical Vertebrae
