- Levator anguli orisThe levator anguli oris is a deep facial muscle running from the maxilla's canine fossa to the mouth's corner, which it raises.
- Levator labii superiorisThe levator labii superioris is a flat facial muscle running from the lower orbital rim into the upper lip, which it lifts.
- Levator nasolabialisLevator labii superioris alaeque nasi: a narrow muscle beside the nose that lifts both the upper lip and the wing of the nostril.
- Levator palpebrae superiorisThe levator palpebrae superioris is the thin muscle in the roof of the orbit that raises the upper eyelid and keeps the eye open.

- Levatores breves costarumThe levatores breves costarum are small fan-shaped muscles at the back of the thorax, each running from a vertebra to the rib just below.
- Levatores longi costarumThe levatores longi costarum are slender slips beside the thoracic spine that pass from a vertebra over one rib to the next.
