12

name the muscles of the anterior thoracic wall from superior to inferior

Deltoid muscles; pectoralis major; pectoralis minor; subclavius muscle; serratus anterior muscle

13

the groove cleft between the shoulder and the chest

Deltopectoral groove (cephalic vein is here)

14

describe the branches off of the thoracoacramial trunk of the axial artery

Pectoral; Deltoid; Acromial; Clavicular.

15

Name the intercostal muscles from the superior to the inferior

External intercostal muscles and membrane (diagnal towards the belly button); Internal intercostal muscles and membrane (towards the chin). Innermost intercostal muscles.

16

what three structures occupy the intercostal groove?

Intercostal vein; Intercostal artery; Intercostal nerve.

17

attach the posterior surface of the sternum to the costal cartilages of the mid to lower true ribs and functions to depress the costal ends of the ribs.

Transversus thoracis muscles

18

arise from the lower ribs near the angles and ascend 2-3 ribs to insert again near the angle of the rib. They are thin slips of muscles deep to the intercostal vessels and nerve and blend with the innermost intercostal muscles. They are more prominent in the lower aspect of the rib cage and assist in pulling the ribs downward.

subcostal muscles

19

name the layers of the pericardial sac from the external to the internal:

Fibrous paricardium; Pariatal paricardium; Visceral paricardium. The pariatal and visceral paricardium together are serous pericardium.

20

Serous-lined space located posterior to the ascending aorta and pulmonary trunk, anterior to the superior vena cava, and superior to the left atrium. As the heart tube folds on itself during development, the transverse sinus marks the separation between the venous end and the arterial end of the heart tube.

Transverse pericardial sinus

21

Serous-lined blind cul-de-sac bordered by the 4 pulmonary veins and the inferior vena cava. The posterior wall of the oblique sinus is the parietal pericardium lining the posterior aspect of the fibrous sac, and the anterior wall of the sinus is the visceral pericardium covering the posterior surface of the heart.

Oblique pericardial sinus

22

anterior descending branch of cervical plexus; arise: C3-C5; enters mediastinum & thorax on route to lung; supplies diaphragm

phrenic nerve

23

drain blood from pericardium; course with phrenic n. & pericardiacophrenic a. lateral to heart; drain into internal thoracic v.

pericardiacophrenic vessels

24

arise: right aortic sinus; runs: coronary sulcus; supplies r. atrium, ventricles/intervent. septum (parts), SA/AV nodes; terminates as PDA

right coronary artery

25

branch of RCA; supplies SA node, part of pulmonary trunk & right atrium; in some cases SA node is supplied by LCA

Sinuatrial artery

26

branch of right coronary a.; near inferior margin of heart; supplies apex & right ventricle of heart

Right marginal artery

27

arise: left aortic sinus; supplies left atrium, part of both ventricles, ant. part of interventricular septum, AV node; br. into LAD & LCX

Left Coronary artery

28

terminal br. of RCA; travels in posterior interventricular groove to apex; supplies both ventricles; may form an anastomosis with LAD

Left anterior descending artery (LAD; anteror interventricular)

29

branch of LCA; supplies left atrium & left ventricle; courses left & then posterior in coronary sulcus to diaphragmatic surface

left circumflex artery (LCX)

30

between left atrium & ventricle (in coronary sulcus); termination of great cardiac v.

Coronary Sinus

31

follows LAD: apex to coronary sulcus; follows LCX; joins coronary sinus; drains ventricles & left atrium via tributaries & left marginal v.

Great cardiac vein

32

begins at apex of heart; follows post. interventricular a. (PDA) in post. interventricular sulcus; drains into coronary sinus

Middle cardiac vein

33

drains blood from regions superior to diaphragm into right atrium

SVC

34

IVC

35

right upper part of the heart

Right Atrium

36

myocardial wall separating left and right atria; contains fossa ovalis

Interatrial septum

37

depression located in interatrial septum; superior to IVC; remnant of fetal fossa ovale, which shunted blood from right atrium to left atrium
