-
Spinal Cord (Cervical Portion):
Runs within the vertebral column (backbone). -

Various muscles supporting head movement and posture.
Thoracic Region (Upper Back)

-
Spinal Cord (Thoracic Portion):
Runs within the vertebral column. -
Rib Cage (Posterior Portion):
Protecting the lungs and heart. -
Lungs (Posterior portions):
Thelungs extend primarily to the back. -
Spinal Cord (Thoracic Portion):
Runs within the vertebral column. -
Various muscles:
Including the trapezius, rhomboids, and latissimus dorsi.
Lumbar Region (Lower Back)
The lower back, extending from the bottom of the rib cage to the sacrum (bony plate at the base of the spine).
-
Spinal Cord (Lumbar Portion):
Runs within the vertebral column. -
Kidneys (Posterior portions):
Located on either side of the lumbar spine, somewhat protected by the lower ribs. -
Muscles of the Lower Back:
The erector spinae muscles are important for posture and movement.
Sacral Region (Base of Spine)
The triangular bone (sacrum) forming the base of the spine.
-
Sacrum:
A fused bone forming the posterior pelvic girdle. -
Coccyx (Tailbone):
Located inferior to the sacrum.
