Starting in the spinal cord, trace a motor pathway to the adductor.

The following are the Spinal cord pathway, both sensory and motor.

peripheral nerve -> sensory pathway --> posterior root -> posterior horn -> anterior horn -> anterior root -> motor pathway

This is also the ascending and descending fiber pathways

* ascending / incoming / afferent / sensory pathways:
- sensory impulses carry different "feeling" (light touch, hot, cold) 
Fiber pathways from specific area of body
* outgoing / efferent / descending / motor pathways:
- cause muscles to act
- in white matter of spinal cord
- cross over from one side of body to another in different levels (what
effects in phenomenon of left-sided stroke affecting the right side of
the body)

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
