A muscle or anatomical structure that pulls or lifts a body part upward.
From Latin ascendere (to climb) with the suffix -or (one who does). Medieval Latin anatomists used this term to name muscles that perform upward movements.
Your levator scapulae and deltoids are ascensors—anatomy uses Latin action words to name every muscle by what it does, creating a kind of 'anatomical verb dictionary' that doctors across all languages can understand.
