The Vertebrate Anatomy

Vertebral Column About 70 cm long in adult 5 major divisions (cervival, thoracic, lumbar, sacrum, coccyx)

Intervertebral Discs Act as shock absorbers Allow spine to flex and extend 25% of spine

Disc Damage Herniated disc Rupture of annulus fibrosus Protrusion of spongy nucleus pulposus Treatment: moderate exercise, massage, heat therapy, painkillers, removal

Cervical Vertebrate Seven (C1-C7) C3-C7 have same characteristics C1-C2 special

Thoracic Vertebrate 12 of them  T1-T12 Body is heart shaped

Lumbar Vertebrate Receives the most stress L1-L5

Secrum S1-S5

Coccyx Tailbone Useless bone (slight support of pelvic organs)

Vertebral Column Scoliosis Kyphosis Lordosis Curvature in thoracic region Kyphosis Hunchback Lordosis Swayback, in order to keep balance bend back backwards
