CHEST AND LUNGS Flashcards
WHAT IS THE DIRECTION OF THE EXTERNAL INTERCOSTAL MUSCLES
MOVE DOWN AND FORWARDS
WHAT IS THE FUNCTION OF THE EXTERNAL INTERCOSTAL MUSCLES
MOVING THE RIB CAGE
AT WHAT ANGLE DO THE INTERNALS LIE TO THE EXTERNALS
90 DEGREES
THE INNERMOST INTERNAL INTERCOSTAL MUSCLES LIE IN THE SAME …………………. BUT A LITTLE MORE ……………….
ORIENTATION
HORIZONTALLY
WHERE DOES THE INTERCOSTAL BUNDLE SIT
IN THE INTERCOSTAL GROOVE
WHAT DOES THE INTERCOSTAL BUNDLE CONSIST OF
THE INTERCOSTAL VEIN, ARTERY AND NERVE
THE THORACIC CAGE CONSISTS OF ……….. PAIRS OF RIBS THAT ARTICULATE ……………….. WITH THE ……………….. COLUMN
12
POSTERIORLY
VERTEBRAL
WHAT IS THE ROLE OF THE THORACIC CAGE
PLAYS A PART IN RESPIRATION
PROTECTS THORACIC ORGANS AND ORGANS OF THE UPPER ABDOMEN
HOW MANY PAIRS OF RIBS ARTICULATE WITH THE STERNUM
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
WHERE DO THE INTERNAL THORACIC ARTERIES ORIGINATE FROM
SUBCLAVIAN ARTERIES
WHAT MUSCLES DOES QUIET INSPIRATION USE
CONTRACTION OF EXTERNAL INTERCOSTAL MUCLES
WHAT MUSCLES DOES FORCED INSPIRATION USE
CONTRACTION OF EXTERNAL INTERCOSTAL MUCLES BUT ADDITIONALLY THE SECONDARY MUSCLES AROUND NECK AND BACK
WHAT MUSCLES DOES FORCED EXPIRATION USE
CONTRACTION OF INTERAL INTERCOSTAL MUSCLES
WHAT MUSCLES DOES QUIET EXPIRATION USE
IT IS A PASSIVE PROCESS SO ONLY RELAXATION OF EXTERNALS
WHAT IS CONSIDERED AN ATYPICAL RIB
EITHER ONE ARTICULATION, DIFFERENCE IN MORPHOLOGY OR A FLOATING RIB
WHY IS RIB 1 CONSIDERED AN ATYPICAL RIB
RIB 1 IS FLAT, SHORT AND HAS ONLY 1 ARTICULATION
WHY IS RIB 2 CONSIDERED AN ATYPICAL RIB
RIB 2 HAS A DIFFERENT MORPHOLOGY AND A ROUGH AREA WHERE SERRATUS ANTERIOR ATTACHES
WHY IS RIB 10 CONSIDERED AN ATYPICAL RIB
RIB 10 HAS ONLY ONE ARTICULATION
WHY IS RIB 11 CONSIDERED AN ATYPICAL RIB
RIB 11 IS A FLOATING RIB
WHY IS RIB 12 CONSIDERED AN ATYPICAL RIB
RIB 12 IS FLOATING RIB
WHAT IS CONSIDERED TO BE A TRUE RIB
IF THE RIB IS INDIVIDUALLY ATTACHED TO ITS OWN CARTILAGE
WHY ARE RIBS 8-12 CONSIDERED FALSE RIBS
8-10 ATTACH TO THE COSTAL CARTILAGE SUPERIOR TO THEM
11 - 12 ARE FLOATING
WHAT ARE THE TWO MECHANISMS OF RESPIRATION
PUMP HANDLE - MOVEMENT OF STERNUM
BUCKET HANDLE - MOVEMENT OF THE RIBS
T1 VERTEBRA ARTICULATES WITH WHAT RIB
RIB 1
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
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
