trochlea
This term is used exclusively within medical and anatomical contexts to describe structures that function like pulleys. It carries a neutral, technical tone and is typically employed by surgeons, anatomists, and physical therapists to specify the exact point of articulation or tendon guidance in a joint.
Because it is derived from Latin and Greek, the word follows a specific morphological pattern. While it is a countable noun, the plural form is irregular, changing the final vowel to reflect its classical roots.
