Heart

Question 1

pericardium

Answer 1

unyielding dense CT, mesothelium, produce serous fluid to decrease friction, innervated by PHRENIC

Question 2

cardiac tamponade

Answer 2

acute pericardial effusion, Becks triad

Question 3

becks triad

Answer 3

JVD, muffled heart sounds, decreased arterial pressure

Question 4

surfaces of heart

Answer 4

auricles, inter ventricular sulcus, pericardial reflection, ligament arteriousum, coronary sulcus

Question 5

what is coronary sulcus

Answer 5

where most of the veins empty, then empties into RA

Question 6

coronary sulci

Answer 6

grooves/fissures for vessels to avoid pressure/friction

Question 7

thesbian veins

Answer 7

in myocardium, empty direct into chambers

Question 8

RCA brances

Answer 8

posterior descending, R marginal

Question 9

LCA branches

Answer 9

l circumflex, anterior inter ventricular (decending)

Question 10

CAD

Answer 10

cholesterol deposits damage coronary arteries, thick tunica intima

Question 11

body compensation fro CAD

Answer 11

collateral growth, reverse flow (thespian), endow bypass via vasa vsorum or CABG

RA

Answer 12

gets venous blood, pectinate muscle, lumbus/fossa ovalis

Question 13

fossa ovalis

Answer 13

patent in 20-25%, tricuspid valve

Question 14

RV

Answer 14

conus arteries, pap muscle, chord tend, trabecular carnea, semilunar pulm valve, moderator band

Question 15

coronary artery perfuson

Answer 15

during diastole, relaxed myocardium,

Question 16

mitral valve is in

Answer 16

left atrium

Question 17

heart sympathetic

Answer 17

T1-T4

Question 18

heart parap

Answer 18

vagus (long pregang)

Question 19

blunt trauma to sternum will injure which chamber?

Answer 19

right ventricle

Question 20

where is oblique pericardial sinus

Answer 20

inside pericardial sac, between pulmonary veins. between left atrium and esophagus.

Question 21

where is transverse pericardial sinus

Answer 21

behind ascending aorta and pulm trunk

Question 22

what does transverse pericardial sinus allow

Answer 22

expansion of great vessels during systole

Question 23

what does oblique sinus allow for

Answer 23

expansion of left atrium during inhalation

Question 24

what heart issues can compress esphagus

Answer 24

left atrial enlargement, mitral valve issues

Question 25

what is in moderator band

Answer 25

right branch of atrioventricular bundle

Question 26

right coronary artery supplies what

Answer 26

right ventricle, right atrium, posterior 1/3 of IV septum

Question 27

what artery branch supple SA/AV nodes

Answer 27

atrial and SA nodal branches, off of right coronary… issues can lead to heart block

Question 28

what artery supplies the inter ventricular septum

Answer 28

anterior inter ventricular- branch of Left coronary

Question 29

perkinje fiber achilles

Answer 29

conduction is in endocardium, blood is in epicardium..perkinje perfused last so die first and mess up conduction

right posterior decending runs with

Answer 31

middle cardiac vein

Question 32

Answer 32

small cardiac

Question 33

what vein runs with right circumflec

Answer 33

small cardiac

Question 34

what valves make S1 sound

Answer 34

tricuspid and mitral

Question 35

atropine effect

Answer 35

increase heart rate (block parasympathetic)

water bottle sign

Answer 36

pericardial effusion/pericardidits

Question 37

Answer 37

diastole
