1

what 2 things make up the pericardium

1. fiberous (non elastic)
2. Serous pericardium

2

where is the pericardial cavity located

between the visceral and parietal layer

3

what are the 2 pericardial sinuses

transverse sinus and oblique sinus

4

where is the transverse sinus located

between the arterial and venus end of the heart

5

what is located behind the transverse sinus

SVC

6

What is located in front of the transverse sinus

ascending aorta and the pulmonary trunk

7

where is the left atrium located

behind the left atrium

8

in bypass arteries are clamped thru what sinus

transverse pericardial sinus

9

a surgeon can stick their hands thru what sinus

transverse pericardial sinus

10

inflammation of the pericardium is known as

pericarditis

11

what is a pericardial effusion

collection of fluid in the sac

12

what is a cardiac tamponade and what are 2 symptoms associated with it

when blood collects in the pericardial cavity and compresses the heart . increased heart rate- to compensate for the pressure . and engorged veins in the veins and neck

13

how is cardiac tamponade treated? Where does the needle go specifically

pericardiocentesis - done at the LEFT 5th ICS near the sternum or thru the LEFT infrasternal angle

14

t/f the heart is behind the sternum and the rib cage

true

15

where do the grooves aka sulci of the heart meet

at the crux

16

where is the apex of the heart

LEFT 5th ICS

17

what chamber is found at the apex of the heart

Left ventricle

18

what 2 structures makes up the right border of the heart and what is the majority of it

SVC, right atrium --> right atrium is the majority of the right border of the heart

19

what 4 structures make up the L border of the heart

Left atrium, L ventricle , aortic arch, pulmonary arch

20

what makes up the inferior border of the heart

right ventricle

21

what makes up the superior border of the heart

left atrium

22

a person is stabbed in the sternocostal aka anterior surface of the heart what is most likely to be injured

right ventricle

23

what makes up the majority of the anterior surface of the heart

right ventricle

24

what chamber makes up the base of the heart

left atrium

25

what sulci is located on the right atrium

sulcus terminalis

26

in which chamber is the SA node located

in the right atrium

27

are pectinate muscles found in the atrium or the ventricles

pectinate = atrium

28

are trabeculae muscles found in the atrium or the venttricles

trabeculae carne = ventricles

29

what are the 3 kinds of trabeculae that are found in the right ventricle

1. ridges- fixed
2. bridges- connect ridges
3. papillary -concial projections

30

what band is found in the right ventricle and what happens if you cut it

septomarginal band - it containts the right branch of the bundle of his , if you cut in the right ventricle cant contract
