@atomedgeanatomy: Did you know the longissimus as in the name is the longest muscle in your body? Try see if you can spot it... It runs from your lower back all the way up to the base of your skull, helping you stand tall, bend backward, and keep your spine stable. Next time you sit up straight, thank your longissimus ... it’s got your back, literally! #AnatomyFacts #Longissimus #PosturePower #muscle #musclesystem #learnsomethingnew #medstudentlife #anatomy #humanbody #3danatomy #medicaleducation #medicalanimation
