Question 5

Vertebral column (and its disorders)

Answer 5

Four major curvatures in adults
Cervical: anterior
Thoracic: posterior
Lumbar: anterior
Sacral and coccygeal: posterior

At birth, column is C shaped
When head is raised, cervical curve appears
When sitting and walking begin, lumbar curve develops

Abnormal curvatures
Lordosis. Exaggeration of lumbar
Kyphosis. Exaggeration of thoracic
Scoliosis. Lateral, often accompanied by kyphosis

Question 6

Atlas

Answer 6

Atlas: first cervical vertebra
Articulates with skull and allows “yes” movement
No body and no spinous process

Question 7

Axis

Answer 7

Axis: second cervical vertebra
Dens: a process of the axis that extends superiorly into the vertebral foramen of the atlas
Allows rotation of the atlas on the axis, the “no” movement
