1

Kyphosis

convex curvature of spine
thoracic and sacral
excessive: hunchback

2

Lordosis

concave curvature of spine
cervical and lumbar
excessive: swayback/hollow back

3

Scoliosis

abnormal lateral curvature of spine

4

Vertebral foramen sizes

largest: cervical
middle: lumbar
smallest: thoracic
*to accomodate cervical and lumbar enlargements of spinal cord

5

Primary curvatures of spine

develop during fetal period and remain throughout life
thoracic and sacral kyphosis

6

Secondary curvatures of spine

not obvious until infancy
cervical and lumbar lordosis

Functions of vertebral column (4)

muscle attachment/movement
restriction of movement (stability)
protection of spinal cord
support of body weight

15

Parts of Vertebrae (5)

body
arch
vertebral foramen
vertebral notches
processes (spinous, transverse, and articular)

16

Vertebral arch

formed from pedicles and laminae

17

Vertebral foramen

forms the vertebral canal (central canal)
contains spinal cord, meninges, fat, nerve roots, blood supply

18

Vertebral notch

notches form IV foramina (lateral recess)
houses spinal nerve roots

19

Vertebral processes

1 spinous process
2 transverse processes
4 articular processes

20

Function of spinous/transverse processes

muscle attachment and movement

21

Function of articular processes

restriction of movement

22

Function of vertebral notch

protection of spinal cord

23

Function of vertebral body

support of body weight
