Curves in the spine

primary: Thoracic and sacral curves are concave (present at birth) -Secondary: cervical and lumbar appear after birth convex appear when a kid is learning how to walk

Difference between a women and a man pelvis

Male: large, heavier, and more narrow. Public arch angle greater then 90 Female: is rounder has a flared iliac crest, eider pelvic opening, public arch angle less then 90 degrees
