What is another word for erector spinae?
Pronunciation: [ɪɹˈɛktə spˈɪniː] (IPA) 
The erector spinae muscles, located in the back, are an essential component of human physical support and movement. These muscles are responsible for the extension of the vertebral column and allow for lateral movements of the trunk. There are a few synonyms for the erector spinae muscles, including the sacrospinalis, iliocostalis, and longissimus muscles. These are all names for different portions of the muscles, which extend along the spine from the sacrum to the skull. While each muscle has a slightly different function, they work together to keep the spine strong and stable during movement and exercise. Proper strengthening of the erector spinae muscles can help prevent common back injuries.
