Spine Anatomy

Description

Centered in the midline, the vertebral column is highlighted from the atlas and axis in the upper cervical region down through the thoracic and lumbar vertebrae to the sacrum and coccyx, framed laterally by the ribs and the paired hip bones. Vertebral bodies align inferiorly beneath the skull, with the thoracic segment lying posterior to the sternum and costal cartilages while the lumbar spine descends into the pelvic inlet. Cervical lordosis, thoracic kyphosis, and lumbar lordosis can be appreciated as a continuous sagittal contour even when presented in a frontal, upright stance. Alignment matters. An anterior, full-skeleton perspective is the working view for many baseline teaching and clinical measurements: spinal midline relative to the sternum and pubic symphysis, rib symmetry, and pelvic tilt give fast cues to coronal balance. This is the orientation used when screening idiopathic scoliosis on standing AP radiographs, where vertebral rotation, rib hump correlation, and compensatory lumbar curves are judged alongside shoulder and iliac crest height. It also supports discussion of sex-linked pelvic morphology, including a broader pelvic inlet and subpubic angle that influence lumbosacral alignment and load transfer at L5 to S1. Use this asset in gross anatomy courses covering the axial skeleton, kinesiology modules on posture and spinal curvature, and radiology or orthopedic teaching files introducing AP spine and scoliosis concepts. It also fits patient-facing education for back pain, osteoporosis-related vertebral compression fractures, and posture counseling when you need a neutral, anterior reference with clear regional segmentation.
