1

Forms the central axis of the skeleton
Centered in the midsagittal plane of the posterior part of the trunk
Upper limbs supported indirectly via the ribs which articulate with the sternum which articulates with the shoulder girdle
Articulates with each hip bone at the SI joints
Fibrocartilage disks interposed between
Held together by ligaments and is jointed and curved so that is has considerable flexibility and resilience

Vertebral column/spine

2

4 functions of the vertebral column

Encloses and protects the spinal cord
Acts as a support for the trunk
Supports the skull superiorly
Provides attachment for the deep muscles of the back and the ribs laterally

3

Small segments of bone that compose the vertebral column

Vertebrae

4

In early life the vertebral column usually consists of 33 small, irregularly shaped bones divided into 5 groups named according to the region they occupy

Cervical
Thoracic
Lumbar
Sacral
Coccygeal

5

7 superior most vertebrae occupy the region of the neck

Cervical

6

Succeeding 12 bones lie in the dorsal/posterior portion of the thorax

Thoracic

7

5 vertebrae occupying the region of the loin

Lumbar

8

Next 5 vertebrae located in the pelvic region

Sacral

9

Terminal vertebrae in the pelvic region vary from 3-5 in number in adults

Coccygeal

10

24 vertebral segments in the upper 3 regions that remain distinct throughout life

True/moveable vertebrae

11

The pelvic segments in the 2 lower regions; undergo a change in adults where the sacral segments usually fuse into one bone called the sacrum & the coccygeal segments (coccyx) also fuse into one bone

False/fixed vertebrae
