Agenda:

Page 2: Bones of the Axial Skeleton Continued Agenda:. Double curvature of the spine - adaptation for upright posture Vertebral Column C1 = atlas C2 = axis C1

Double curvature of the spine -adaptation for upright posture

Vertebral Column

C1 = atlasC2 = axisC1 – C7 = cervical vertebrae

T1 – T12 = thoracic vertebrae

L1 – L5 = lumbar vertebrae

Page 219 – Draw and label a vertebra

Please know:•Superior articular process•Inferior articular process•Vertebral body•Spinous process•Transverse process

How to distinguish between vertebrae types

Cervical Thoracic Lumbar

smaller, more larger, U body, largest, doesflexible, bifid shape, rigid, not articulateprocess, narrow articulates with with ribs, largenerve passage, the ribs, medium nerve passage,no rib articulation, nerve passage circular body oval body shape shape (oval)

Thoracic Cage True ribs (pairs 1 – 7)False ribs (pairs 8 – 12)Floating ribs (pairs 11 – 12)
