What’s in a name:
- levator (n.) from medical latin levator “a lifter,” from Latin levatus, past participle of levare “to raise” (see lever).(Etymology Online)
- scapula (n.) “shoulder blade,” 1570s, Modern Latin, from Late Latin scapula “shoulder,” from Latin scapulae (plural) “shoulders, shoulder blades,” perhaps originally “spades, shovels,” on notion of similar shape, but animal shoulder blades might have been used as scraping tools in primitive times, from PIE *skap-, variant of *skep- “to cut, scrape” (see scabies).(Etymology Online)
- A lifter of the scapulae

Origin: Transverse process of the first four cervical vertebrae (posterior tubercles of C3 and C4 transverse processes) (8, 11).
Insertion: Medial border of the scapula from pointed edge close to origin of the spine of the superior angle of the scapula (11, 19)
Nerve: Primarily innervated by cervical nerves 3 and 4, via the cervical plexus, originating from cervical roots 3 and 4. Additional innervation from the dorsal scapular nerve and the C5 trunk of the brachial plexus (with communicating nerves from cervical nerve 4), which continues on to innervate the rhomboids (8, 11, 20).
