Why are some neck muscles called the scalenes?

The anterior and middle scalene muscles lift the first rib and bend the neck to the same side; the posterior scalene lifts the second rib and tilts the neck to the same side. The muscles are named from Ancient Greek σκαληνός (skalenos) 'uneven'.

because health skills are tools and strategies and also practical skills are also something you need to learn (like tools and strategies) and put it in reality.
