pulmonary embolism - Correct Answers -clot from leg to lung causing respiratory
distress
aspirated foreign body more likely in - Correct Answers -right main bronchus because it
is more vertical, wider and shorter
adeonpathy at supraclavicular - Correct Answers -indicates bronchiogeic carcinoma if
on right side expected in thorax if on the left expected in thorax, abdomen or pelvis

azygos v drains to SVC
costal cartilage of rib 2 meets sternum
xiphisternal junction - Correct Answers -central tendon of diaphragm
T9 if supineT9-T10 if standing
,pericarditis - Correct Answers -fluid in pericardial cavity that can cause cardiac
tamponade (impaired venous flow causing impaired cardiac output
transverse pericardial sinus - Correct Answers -posterior to aorta and pulmonary trunk,
allows for clamping of the vessels together
pericardial BS - Correct Answers -pericardiacophrenic (major) musculophrenic, int
thoracic, inf phrenic, thoracic aorta
pericardium innervation - Correct Answers -phrenic n (C3-C5)[same as diaphragm]
causing referred pain to lateral neck and shoulder
vagus n
sympathetic trunk
rough muscle in atrium vs ventricle - Correct Answers -pectinate in atrium
trabeculae carne in ventricle
RV vs LV valves - Correct Answers -right tricuspid left bicuspid with thinner but more
chordae tendinae(try before you buy)
fossa ovalis - Correct Answers -in RA
coronary, SVC and IVC drain to - Correct Answers -RA
crista terminales - Correct Answers -separates smooth and rough in the RA
correlates with suculus terminales exteriorly
septomarginal trabeculae - Correct Answers -in RV, has a moderator band which is an
extension of the conducting system of the heart
LV vs RV - Correct Answers -right is thinner because pumps to lung
diastole vs systole - Correct Answers -dilation and filling of the heart, systole is the
ventricular contraction
aortic valve - Correct Answers -has semilunar cusps, coronary arteries open to right and
left When aortic valve closes it allows for blood to be pushed through coronary arteries
and the body
CABG or triple coronary artery bypass graft - Correct Answers -uses greater saphenous
v or int thoracic a
innervation of heart - Correct Answers -cardiac plexus:
symp T1-T4 or 5: norepinephrine, inc HR and contraction
parasymp: cholinergic, dec HR and contraction force
, SA node location
AV node location - Correct Answers -SVC and crista terminalis
posterior inf interatrial septum near coronary sinus
AV node blood supply - Correct Answers -right and left coronary a
bundle of his blood supply - Correct Answers -left coronary a
epithelium of nasal cavity vestibule - Correct Answers -SSE with hair (the nare)
nasal cavity respiratory epithelium - Correct Answers -pseudostratified colmnar with
cillia and goblet cells
lamina propria of respiratory portion of nasal cavity - Correct Answers -warms air and
can cause congestion if engorged by allergies or infection (mucus glands with serous
demilunes that secrete lysozyme)
olfactory epithelium of nasal cavity - Correct Answers -pseudostratified columnar
cells of olfactory portion of nasal cavity - Correct Answers -olfactory cells: bipolar and
span olfactory epithelium, sensory cillia on apical end and axons on basal end that join
olfactory n (CN1) and synapse at olfactory bulb, are able to regenerate
supportive (sustentacular) cells: similar to glial
basal cells: renew sensory and supportive cells
brush cells: sense touch, innervated by trigeminal n (CNV)
