What's Wrong with Dumbing Down Anatomy

The human body is an incredible, living, adaptive, self-communicating, always evolving machine that surpasses even our most advanced technological wonders.  Unfortunately, this is not how standard anatomy classes are taught.  With in the medical educational system we are taught more about separate parts rather than totally integrated systems. Essentially we tend to compartmentalize everything as if they were somehow not part of a complete system. Essentially our education system "Dumbs Down" the human body to make it easier to teach students. (Drawing of the upper extremity by Michelangelo).  

My specialization is the treatment of musculoskeletal conditions. Over 20 years ago when I first began my practice, I also looked at the body from this very limited perspective. Fortunately for my patients, my perspective has changed radically. 

You could say that three fundamental areas of knowledge have given me a personal epiphany on how our entire body works as one synergetic interconnected system. These are the myofascial system, the body's kinetic web, and  the concept of tensegrity.

About The Myofascial System

The prefix 'Myo’' refers to muscle, whereas  fascia’ refers to the connective tissue that permeates the entire human body. Fascia is everywhere in the body, weaving through, and connecting every component of the body. Fascia forms a seamless web of connective tissue, which connects, holds, and infuses the tendons, organs, muscles, tissues, and skeletal structures.

To get a better understanding of how interconnected we really are, it is essential that we first understand the significance of fascia.  New discoveries over the last few decades have shown that fascia plays a very important role beyond that of simply serving as a packing material around muscles and organs. Fascia is intimately involved in controlling both the movement patterns and the neurological control mechanisms of the entire body. It is an integral component of a body-wide signalling system. Interestingly, it has been shown that fascia is full of neurological receptors (even more so than muscle tissue). This is rather astounding, especially when of realizes that most physicians do not consider how fascia plays such a key role.

Consider the image to the right, this is a dissection of the elbow (proximal lateral elbow region). What  makes this dissection unique is that the muscles are dissected away from the body instead of the fascia. The strands you see show the convergence of this connective tissue to link all the structures surrounding the lateral elbow (lateral epicondlye).   This is a great example of how convergence of multiple strands of connective tissue can form a interconnected functional matrix.  If we did the same type of dissection technique in other areas of the body (shoulders, hips, knees etc.) we would discover a very similar pattern. Multiple stands of connective tissue, in complete continuity, with no visible separation from each other.

Text book anatomy looks nothing like this. The anatomist's scalpel has removed all the fascia leaving the impression of  individual muscles, all by themselves, each performing their own separate actions. Standard anatomy is actaully an anatomical fantasy, and a rather dumbed-down one at that!

Muscle Contraction - How Things Really Work

Standard texts for anatomy and biomechanics teach us that motion is created by the contraction of muscles. These muscles have tendons at each end that insert directly into bone. When a muscle contracts, the two ends of the muscle (origin and insertion) are pulled towards each other to create motion.

Although this description is quite true, it is also a reductionist perspective about what is really happening in the body. Let me explain how an understanding of fascia can help us develop a new, more holistic perspective about how the body performs its actions. This will give us a better understanding about why looking at the bigger anatomical picture can help us to better resolve many complex musculoskeletal conditions. 

First, consider the fact that the muscle fibers actually originate from, and insert into, both the surrounding fascial fibers as well as the bone. These fascial fibers, in turn, insert into multiple regions of other bones, and even into other adjacent muscles. These additional points of contact provide muscles the ability to generate force in multiple directions (a three-dimensional model of movement).

Learning about these multiple points of fascial attachment – all working across three-dimensions – completely changed my understanding of the biomechanics of muscle action, and also provides me with a much more functional understanding of muscle contraction. Now, when I look at, and analyze muscle contraction, I realize that only certain sections of the muscle contract to perform an action (not the entire muscle).

In actuality, groups of muscles usually work together as functional units to execute any action. For example, some muscles may act as the primary movers (agonists) to perform an action, while other muscles act as antagonists; while yet others act as synergists and others as stabilizers. In all these activities fascia is the key component that allows these muscles to work together as functional units by aiding in coordinating their actions across multiple joints.

Depending on the degree of motion, and the amount of force that is needed, each muscle will then contract very specific areas of the muscle, rather than the entire muscle. These very specific motions are largely coordinated by the neurological receptors embedded in the fascia, and are not controlled by the brain alone.

The Kinetic Web 

Your body is made up of a remarkable series of kinetically linked systems which, when working efficiently, store and release impressive amounts of energy without injury!

Essentially, each body acts as a single large three-dimensional Kinetic Web, in which force or tension from one area directly affects multiple structures in both localized areas, and structures far from the site of tension.

The Kinetic Web can be thought of as a linked series of kinetic chains. Each kinetic chain is made up of individual links (the various components of your musculoskeletal system, nervous system, and cardiovascular system) which are connected to each other to form a three-dimensional Kinetic Web. When you have changes in one area of your body, there will be cascading effects throughout the entire body, and thus multiple structures in your kinetic web will be affected.

Any weak link in this chain not only generates its own set of problems, but also creates problems and compensations somewhere else in the body. For example, when a structure in your hip, groin, or pelvis is injured or restricted, it becomes unable to effectively perform its normal functions such as walking, climbing up stairs, or even being intimate with your significant other.

Kinetic Lines

Kinetic Lines (whole body fascial interconnections) are actual physical structures that have been mapped out and dissected. These are actual physical structures that connect our bodies together. Researchers and clinicians such as Thomas Myers (Anatomy Trains), Luigi, Carla and Antonio Stecco (Fascial Manipulation) have spent decades researching these interconnections.

Think of these Kinetic Lines as vectors for force transmission, they are not only connections, but are also a continuous line of tension. In the case of Thomas Myers, he has mapped out seven primary lines of fascial connection throughout the body. These are the:
  • Superficial Back Line (SBL).
  • Superficial Front Line (SFL).
  •  Lateral Line (LL).
  • Spiral Line (SL).
  • Arm Lines.
  • Functional Lines.
  • Deep Front Line (DFL).
Other researches have mapped out slightly different connections, but the general concepts remain very similar.  For example let us consider the Superficial Back Line (SBL)

 SBL Dissection
Click image to view a video of the dissection of the Superficial Back Line (SBL).  As you view this video, consider how the fascia on the bottom of the foot connects directly into the calf muscles, hamstrings, low back, into the neck, and even to the top of the head. In fact, they are all inter-connected and inter-dependant.

Most standard anatomy texts are just starting to acknowledge the importance of these connections

Tensegrity – Tension Plus Integrity

A key concept in understanding your body as an interconnected kinetic web is known as Tensegrity. Tensegrity is a structural principle that describes the integrity of a structure based on the balance of tensional forces rather than just its compressive nature.

First a little history; the term 'Tensegrity' was made popular in the 1960’s by a neo-futuristic architect by the name of Richard Buckminister “Bucky” Fuller (1895-1983). Fuller came up with this term when examining the highly creative sculptures of Kenneth Snelson. Snelson’s sculptural works are composed of both flexible and rigid components. Snelson uses the term ‘floating compression’ instead of ‘tensegrity’ to describe his sculptures.

The geodesic dome is a superb example of an architectural structure that uses the concepts of tensegrity. Due to its structure, the geodesic dome is an incredibly stable building due to all the pressure being distributed throughout the entire framework. I remember my sense of awe and wonder when I saw my first geodesic dome as a child at the 1967 World's Fair in Montreal (The Biosphere). Even then, I and many other, knew that we were looking at something special!

With regards to how tensegrity relates to the human body, I will refer to an analogy used by Thomas Myers of Anatomy Trains. Standard anatomical perspectives teach that our skeleton provides a strong stable framework to support the array of soft tissue structures that are attach to it.  This is a concept of ‘continuous compression’ in which the osseous structure of the body provides structural integrity.

This is the same concept we use when building skyscrapers, where each layer of the building provides support for the next layer, and is built on a strong base of stability (a Linear Model). The problem when applying this concept to our human body is that this is a static model (not reality).  Yes “continuous compression” works well in building construction, but not so well in explaining the structural integrity of dynamic human bodies that are in continual motion. 

Think about this, without the muscles, ligaments, tendons, and connective tissue, the framework (our skeleton) would simply collapse. Thomas Meyers uses the analogy of a sailboat to describe this concept. He compares the mast of the boat to our skeletal system and its rigging to our myofascial system. When the wind catches the sail of a boat it directs an incredible force into the mast, yet the mast does not come toppling down because of the tensional balance of its rigging. When one side of the rigging becomes tight and contracted, while the rigging on the other side of the boat becomes loose and movable. That is, until the wind changes and the sail is then pushing in another direction which requires the line of tension to shift to the other side. This describes a dynamic system where a rigid structure (the mast) can take on dynamic qualities because of it tensional system (its rigging).

In the same way, our skeletal system maintains its integrity due to the balance of tensional forces provided by our myofascial system. We can run, jump, move, take our bodies into a thousand contorted positions, and return to a state of balance all because of this concept of tensegrity.

Tensegrity and Injury Resolution

The greatest thing about understanding how our body is totally connected is the how this information helps resolve even some of the most chronic injuries.  Consider this analogy. 

Consider how a soft pliable ball reacts to compressive forces. An interesting thing occurs when we take a ball that is about seven inches in diameter (like the ones we use for myofascial release of the abdomen), and compress it with our hands. 

When we grasp the ball and squeeze hard, the area that we are squeezing contracts while the rest of the ball expands.  If we then take some type of mechanical device and squeeze even harder until the ball bursts, we would find the area of rupture in the ball is the weakest part of the material. Interestingly, the point of rupture is often located far from the point of applied force.

The same thing occurs in the human body.   Previous injuries, muscle imbalances, lack of exercise, mental stress (anxiety), poor nutrition, and a host of other problems all create weak links in your body’s kinetic chain.  These are areas where the body is most susceptible to injury. When increased stress is applied to the body, the entire body tries to compensate.   If the weakest link cannot withstand this additional stress, then an injury occurs at that link.
This tells us that we not only have to consider where the body has developed weak links, but we also have to consider the non-symptomatic areas that are creating this increased stress. Often, these are areas where the patient is not even aware that there is any problem.

The Critical Key

Tensegrity is the key to resolving most chronic musculoskeletal injuries. We must “Look local and Look global”. If there is a problem, we must address both local and global areas. Treatments that only address the symptomatic region (the area of pain) are really an equation for failure.

Bottom line, we are so much more than what appears on the two dimensional pages of an anatomy text (the dumbed-down version). We are complex three-dimensional beings that work as one synergistic organism.  Recognizing this gives us the path to true healing, ignoring this leads us down the path to ongoing dysfunction.
