@instituteofhumananatomy: Your spine isn't one bone — it's 33 individual bones organized into 5 distinct regions. 🦴 Starting at the top, the cervical region runs from C1 to C7 and makes up your neck. Below that, the thoracic region spans T1 to T12, forming the backbone of your chest. Then the lumbar region — the lower back that takes the most punishment in daily life. The sacral region is where things get interesting. What started as five individual bones begins fusing around age 14-16 and completes by around age 30 into one solid structure called the sacrum. And finally the coccygeal region — most people have four individual bones that fuse together into what we commonly call the tailbone or coccyx. Your spine literally grows up as you do.
