Is it yours of mine? (3)

Receptors in the joints, ligaments, muscles and tendons respond to the stimulation that occurs when we move a joint.  Some monitor the rate of movements and the tension of muscles.  Others, signal our position in space.  Still others measure pressure changes… when you turn the steering wheel, then relax your grip, or when a quarterback reaches for the ball, then takes it… and continually tell the brain what is going on.  These messages travel very fast and produce varying degrees of coordination.

Few of us go through the day giving close attention to what each part of our body is doing and where it is.  Yet we are aware, subliminally, and continually process information from proprioceptors, consciously using it to direct action.  Look around at people you know.  One may be a piano player, another a roller skater, another a champion runner.

Proprioceptors are at work here, as they are in the performance of daily chores like washing dishes and driving the car.

Is it yours or mine?

Can you touch your fingertips to each other behind your back?  Can you close your eyes and find your feet?  Can you walk in a straight line?  You probably can.  The reason the that our bodies possess a sense sometimes called kinesthetic (from the Greek for “perception of motion”), and are served by proprioceptors.  (Proprio comes from Latin “for one’s own”).

 

The information that some of the proprioceptors send to the brain creates some of the most fundamental components of our sense of self.  It is the innate intelligence of your body that does the creating of your sense of self.  Without a sense of self, you could not survive in this world.

Why do we say ouch? (2)

Inside the spinal cord, millions of nerve cell bodies in the grey matter process sensory and motor input and handle automatic reflex actions.  Touch a hot stove, and your hand jerks back instantly because of a spinal cord command.  Conscious reactions occur when the spinal cord relays messages to and from the brain via nerve fibers in the white matter.  You feel pain and know you have burned your fingers because a report was sent to your brain by way of the spinal cord as the spinal cord mediated a reflex action in your muscles.

Why do we say ouch!!!

About seventeen inches long, up to three-quarter on an inch thick, and as flexible as a rubber hose, your spinal cord provides the main link between your brain and the rest of your body.  Thirty-one pairs of spinal nerves containing hundreds of thousands of individual nerve fibers emerge through holes in the spinal cord’s bony protector, the spinal column.  Thousands more fibers project from the bottom of the spinal cord in a cluster called the cauda equina or horse’s tail before they, too, exit through the spinal column.

Does it hurt? (3)

The simplest response is a sharp reflex that travels only to the spinal cord, an even speedier means of protection, when it is necessary to snatch back one’s hand from a frying pan.

Our sensory apparatus, with the autonomic nervous system, monitors functions inside the body.  Digestion proceeds, blood circulates, lungs expand and contract.  We are seldom conscious of theses messages.  Yet your innate intelligence is constantly controlling the many trillions cells of your body ALL of the time.

So, make sure to visit your chiropractor weekly in order for your body to have a full nerve supply!

A signal of burning pain or of an ache travels more slowly than a prickling sensation, no more than about six and half feet per second; originate deeper in the skin; or seems to come from a more diffused, generalized area, such as the neck or back.  Thus, we feel a sharp prickling pain first (from a wasp sting for instance), then the slow burn.
