5, as in “Dinner at 5”
Where are INTERVERTEBRAL DICS located?
Between VERTEBRAE
What do INTERVERTEBRAL DISCS consist of?
An inner gelatinous NUCLEUS PULPOSUS surrounded by a collar of collagen fibers and cartilage, the ANULUS FIBROSUS (comprised mostly of fibrocartilage)
What is a HERNIATED DICS
the rupture of the ANULUS FIBROSUS and protrusion of the NUCLEUS PULPOSUS

What allows the nodding motion of the head?
The ATLAS
What allows for side-to-side motion of the head?
The AXIS
Which type of VERTEBRA has TRANSVERSE FORAMINA?
CERVICAL
What passes through the TRANSVERSE FORAMINA?
Blood vessels
What do the THORACIC VERTEBRAE articulate with?
The RIBS
What do the DEMIFACETS articulate with?
The HEAD of the RIB
What do the TRANSVERSE COSTAL FACETS articulate with?
The TUBERCLE of the RIB
Why are LUMBAR VERTEBRAE larger than the others?
They support more weight
What BONE is made up of 5 fused VERTEBRAE?
The SACRUM
What BONE does the AURICLE of the SACRUM articulate with?
The ILIAC BONE
How many fused VERTEBRAE is the COCCYX made of?
3-5, usually 4
What is the main purpose of the STERNUM?
To protect the HEART
What 2 NOTCHES can be found on the MANUBRIUM of the STERNUM?
The CLAVICULAR NOTCH and the JUGULAR NOTCH
Why would you want to avoid the XIPHOID PROCESS during CPR
Because it is easily broken off of the STERNUM
What is a TRUE RIB and how many of them are there?
A RIB that is attached directly to the STERNUM, 7
What is a FALSE RIB and how many of them are there?
A RIB that is attached indirectly to the STERNUM, 5
What is unique about RIBS 11 and 12?
They are FLOATING RIBS, not attached to the STERNUM
What type of CARTILAGE is COSTAL CARTILAGE?
HYALINE
