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
31
WHERE THE MANUBRIUM ARTICULATES WITH THE BODY IS CALLED
THE STERNAL ANGLE
32
THE STERNAL ANGLE OCCURS AT THE LEVEL OF
THE SECOND COSTAL CARTILAGE / VERTEBRATE T4-T5
33
THE STERNAL ANGLE IS IMPORTANT FOR
ORIENTATING RIBS IS WHERE THE ARCH OF THE AORTA IS WHERE THE TRACHEA BIFURCATES
34
THE BODY HAS MANY FACETS FOR ARTICULATIONS WITH COSTAL CARTILAGE OF RIBS WHAT NUMBERS
RIBS 3 - 6

HORIZONTAL
51
THE TRACHEA AND BRONCHUS ARE MADE OF
CARTILAGE
52
THE BRONCHIOLES ARE MADE OF
SMOOTH MUSCLE

59
PASSING ANTERIOR TO THE HILUM OF THE LUNGS IS THE .............. NERVE THIS PASSES THROUGH THE ............. ALONGSIDE THE .................. VENA CAVA
PHRENIC DIAPHRAGM INFERIOR
60
BLOOD ENTERS THE LUNGS VIA THE TWO
PULMONARY ARTERIES
61
BLOOD LEAVES THE LUNGS VIA THE FOUR
PULMONARY VEINS
62
THE SUPPORTING STRUCTURES OF THE LUNGS REQUIRE THEIR OWN BLOOD SUPPLY; WHAT IS IT
THE BRONCHIAL ARTERIES/SUPPLIES
63
THE DIAPHRAGM HAS ........... DOMES, ............. AND ..................
2 LEFT RIGHT
64
THE DIAPHRAGM ATTACHES TO ..................... ........................ 7-10 AND DIRECTLY TO RIBS ...... AND 12
COSTAL CARTILAGES | 11
65

JUGULAR AND SUBCLAVIAN VEINS
66
THE TRACHEA AND OESOPHAGUS LIE ...................... TO THE GREAT VESSELS
POSTERIOR
67
THE TRACHEA LIES ............................ TO THE OESOPHAGUS
ANTERIOR
68
THE LEFT VAGUS NERVE RUNS OVER THE ................... .................... BEFORE BRANCHING OFF TO SUPPLY THE .................... TREE AND THE HEART. THE VAGUS NERVE SPLITS AT THE POINT OF THE ...................................... ARTERIOSUM INTO OTHER BRANCHES, THE VAGUS ITSELF CONTINUING DOWN THE ............................ INTO THE BOWEL
