Proprioception:

"The ability to sense stimuli arising within the body regarding position, motion, and equilibrium."

The basic idea:

Various 'sensors' located throughout the body generate information that is sent to the brain for 'interpretation'. Sensory feedback concerning position, motion and balance is processed for the sense of proprioception.

The brain uses this information to send signals around the body to maintain a 'functional posture' - a program running in the background to move the body as 'required'.

Conscious proprioception.

When we can consciously sense/feel/see:

The relative position of the parts of our body.
The motion of our body.
Our equilibrium - whether we are balanced or not.

Knowing the physiology of proprioception is not necessary to increase awareness of this sense, so I will not go into further details here although I feel it fair to say that the different mechanisms and various proprioceptors ('sensors') involved are not fully understood.

Increased awareness of the body's positioning, balance and state of alignment comes with focusing on the right anatomy and working from the body's Base-Line.

According to:

Base-Line Hypothesis of Human Health and Movement. (part 2)

(BLH part 1)

Position, Motion, Equilibrium.

To describe the position of something you need a reference.
→ The position of the rest of your body is relative to your Base-Line.

To describe a motion (a change in position) a reference is also needed.

→ All movement should originate from your Base-Line muscles.

Equilibrium comes when the body has a full range of movement and is dynamically aligned and balanced.
→ The linea alba being our primary guide for body alignment and balance.

The Body Map in Our Mind.

I believe we have the innate knowledge of what the body is capable when functioning at optimal. Of where our full range of natural movement should take us.

Imagine a 3-D representation of the body, demonstrating movement through innumerable positions, a flow, within the largest possible body bubble - the body extended.
