1

WHAT IS THE DIRECTION OF THE EXTERNAL INTERCOSTAL MUSCLES

MOVE DOWN AND FORWARDS

2

WHAT IS THE FUNCTION OF THE EXTERNAL INTERCOSTAL MUSCLES

MOVING THE RIB CAGE

3

AT WHAT ANGLE DO THE INTERNALS LIE TO THE EXTERNALS

90 DEGREES

4

THE INNERMOST INTERNAL INTERCOSTAL MUSCLES LIE IN THE SAME ...................... BUT A LITTLE MORE ...................

ORIENTATION
HORIZONTALLY

5

WHERE DOES THE INTERCOSTAL BUNDLE SIT

IN THE INTERCOSTAL GROOVE

6

WHAT DOES THE INTERCOSTAL BUNDLE CONSIST OF

THE INTERCOSTAL VEIN, ARTERY AND NERVE

7

THE THORACIC CAGE CONSISTS OF ........... PAIRS OF RIBS THAT ARTICULATE .................... WITH THE .................... COLUMN

12
POSTERIORLY
VERTEBRAL

8

WHAT IS THE ROLE OF THE THORACIC CAGE

PLAYS A PART IN RESPIRATION
PROTECTS THORACIC ORGANS AND ORGANS OF THE UPPER ABDOMEN

9

HOW MANY PAIRS OF RIBS ARTICULATE WITH THE STERNUM

10

10

WHAT IS THE BLOOD SUPPLY TO THE THORACIC CAGE

ANTERIORLY - THE INTERNAL THORACIC ARTERY SPLITS INTO 12 INTERCOSTAL ARTERIES SUPPLYING EACH RIB
POSTERIORLY THE AORTA BRANCHES INTO 12 POSTERIOR INTERCOSTAL ARTERIES
THESE ANASTAMOSE

11

WHERE DO THE INTERNAL THORACIC ARTERIES ORIGINATE FROM

SUBCLAVIAN ARTERIES

12

WHAT MUSCLES DOES QUIET INSPIRATION USE

CONTRACTION OF EXTERNAL INTERCOSTAL MUCLES

13

WHAT MUSCLES DOES FORCED INSPIRATION USE

CONTRACTION OF EXTERNAL INTERCOSTAL MUCLES BUT ADDITIONALLY THE SECONDARY MUSCLES AROUND NECK AND BACK

14

WHAT MUSCLES DOES FORCED EXPIRATION USE

CONTRACTION OF INTERAL INTERCOSTAL MUSCLES

15

WHAT MUSCLES DOES QUIET EXPIRATION USE

IT IS A PASSIVE PROCESS SO ONLY RELAXATION OF EXTERNALS

16

WHAT IS CONSIDERED AN ATYPICAL RIB

EITHER ONE ARTICULATION, DIFFERENCE IN MORPHOLOGY OR A FLOATING RIB

17

WHY IS RIB 1 CONSIDERED AN ATYPICAL RIB

RIB 1 IS FLAT, SHORT AND HAS ONLY 1 ARTICULATION

18

WHY IS RIB 2 CONSIDERED AN ATYPICAL RIB

RIB 2 HAS A DIFFERENT MORPHOLOGY AND A ROUGH AREA WHERE SERRATUS ANTERIOR ATTACHES

19

WHY IS RIB 10 CONSIDERED AN ATYPICAL RIB

RIB 10 HAS ONLY ONE ARTICULATION

20

WHY IS RIB 11 CONSIDERED AN ATYPICAL RIB

RIB 11 IS A FLOATING RIB

21

WHY IS RIB 12 CONSIDERED AN ATYPICAL RIB

RIB 12 IS FLOATING RIB

22

WHAT IS CONSIDERED TO BE A TRUE RIB

IF THE RIB IS INDIVIDUALLY ATTACHED TO ITS OWN CARTILAGE

23

WHY ARE RIBS 8-12 CONSIDERED FALSE RIBS

8-10 ATTACH TO THE COSTAL CARTILAGE SUPERIOR TO THEM
11 - 12 ARE FLOATING

24

WHAT ARE THE TWO MECHANISMS OF RESPIRATION

PUMP HANDLE - MOVEMENT OF STERNUM
BUCKET HANDLE - MOVEMENT OF THE RIBS

25

T1 VERTEBRA ARTICULATES WITH WHAT RIB

RIB 1

26

WHAT ARE THE FEATURES OF T VERTEBRAE

SPINOUS PROCESS
TWO TRANSVERSE PROCESSES
VETEBRAL BODY IS HEART SHAPED
PRESENCE OF DEMI FACETS - FOR ARTICULATION OF HEADS OF RIBS
PRESENCE OF COSTAL FACETS - FOR ARTICULATION OF TUBERCLES OF RIBS

27

NORMAL RIBS HAVE HOW MANY ARTICULAR FACETS AND WHERE DO THEY ARTICULATE

2, ONE ARTICULATING WITH THE DEMI FACET OF THE VERTEBRA ABOVE AND ONE ARTICULATING WITH THE CORRESPONDING VERTEBRA

28

THE STERNUM IS MADE UP OF

MANUBRIUM
BODY
XIPHOID PROCESS

29

THE SUPERIOR ASPECT OF THE MANUBRIUM HAS A DEPRESSION CALLED THE

JUGULAR NOTCH

30

WHAT IS EITHER SIDE OF THE JUGULAR NOTCH

THE STERNOCLAVICULAR JOINTS WHERE THE MANUBRIUM MEETS THE MEDIAL END OF THE CLAVICLES
