"You may think that a sensory or motor neuron is like one long wire running through your body. Not so! In fact, neurons are more like small noodles, lined up in a row but not actually connected."
The linked page has numerous analogies that help to describe a motor neuron.
"Refined motor skills are like "autopilot." Even in light of fatigue, you'll know how to correct your form. "
"So if motor skills are like natural language, then maybe we can apply things we know about the latter to the former. "Natural" motor skills: their fluidity, robustness to perturbation, and extremely precise yet very compliant control, are hard for robots perhaps the same way language is hard for computers."
There is a commonality in terms of energy conversion. Windmills convert wind energy into mechanical energy. The energy generated is used to do something useful like turn an electrical generator or run a water pump. Motor proteins do something like this in that they take the chemical energy from ATP and convert it into the mechanical motion of muscle proteins such as myosin.
"We wondered if bassoon motor skills are like batting practice, but performing music is more like the design of a play or a strategy."
"the primary motor association area is like a map of the body as it contains neurons that control contractions of muscles in different parts of the body. adjacent muscles are controlled
by adjacent neurons."

METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
