Auricles

RIGHT and LEFT
fatty tissue covering atriums

2

Fossa Ovalis

located in right atrium, remembrance of fetal circulation

3

Coronary Sulcus

deep groove between right atrium and ventricle

4

Anterior Interventricular Sulcus

front outside of heart, separates right and left ventricles

5

Posterior Interventricular Sulcus

back (t-shape) outside of heart, separates right and left ventricles

6

Interatrial Septum

inside of heart separates atriums

7

Interventricular Septum

inside of heart separates ventricles

8

Pectinate Muscles

muscles inside of atrium

9

Trabeculae Carneae

muscles inside of ventricles

10

Ligamentum Arteriosum

joins together the pulmonary truck and aorta; remembrance of fetus ductus

11

Chordae Tendeae

chords of the cuspid valves that attached at the papillary muscles of the ventricles, help prevent back flow into atriums

12

Papillary muscles

where the chordae tendeae attaches in ventricles, helps to close atrioventricular valves

13

Sulcus

dividing section outside of heart

14

Septum

dividing section inside of heart

15

Vessels of the heart

Aorta, pulmonary trunk, inferior/superior vena cava, pulmonary veins

16

Epicardium

outermost layer surrounding heart
-visceral pericardium

17

Myocardium

cardiac muscle tissue
-striated uninucleated
-intercalated disc

18

Endocardium

lines inner chamber of heart
-endothelium

19

Parietal/Visceral Pericardium

PERICARDIUM
layers surround body cavity and heart

20

Coronary Sinus

stimulates deoxygenated blood posterior vein from aorta

21

Great Cardiac Vein

follows along anterior interventricular sulcus

22

Small Cardiac Vein

drain upper right area of heart

23

Middle Cardiac Vein

drain myocardium from posterior interventricular artery

24

Posterior Cardiac Vein

drains myocardium from circumflex artery

25

Characteristics of Cardiac Muscle

Intercalated Discs
Striations
Branched
Centrally Located Nucleus

26

Cononary Artery

supplies blood to right atrium, parts located in both ventricles gives rise to
-Marginal artery
-Posterior interventicular artery

27

Pericardium

serous membrane containing serious fluid to reduce friction

28

Mesothelium

simple epithelium tissue lines pericardial cavity and secretes serous fluid

29

Pericardial Cavity

cavity that surrounds heart

30

Fibrous layer

supports heart & vessels in mediastinum located in parietal pericardium
