Question 1 of 5

Concerning the borders and surfaces of the heart:

 

 

(Select all that apply)
A

the right heart border is made up entirely of the right atrium

B

the inferior border of the heart is made up largely of the left ventricle

C

the left ventricle makes up half of the ventral surface of the heart

D

the right ventricle makes up more than half of the inferior (diaphragmatic) surface of the heart.

E

the coronary sulcus forms the boundary between the right and left ventricles

Question 2 of 5

The fibrous pericardium

 

(Select all that apply)
A

is attached to the sternum

B

forms the anterior boundary of the posterior mediastinum

C

derives its sensory innervation from the phrenic nerves

D

is firmly attached to the central tendon of the diaphragm

E

is separated from the parietal layer of serous pericardium by the pericardial cavity

Question 3 of 5

Concerning the external features of the heart

(Select all that apply)
A

both the right and left ventricles contribute to the diaphragmatic (inferior) surface of the heart

B

the root of the pulmonary trunk lies anterior to the aortic root

C

the left atrium, typically, receives three pulmonary veins

D

no part of the left atrium is evident on the anterior aspect of the heart

E

the right atrial appendage overlaps the coronary sulcus

Question 4 of 5

The cardiac apex:

 

(Select all that apply)
A

is formed by the left ventricle alone

B

coincides with the apex beat

C

may be represented on the surface as a point in the left 4th intercostal space in the mid-clavicular line

D

may be represented on the surface as a point in the left 5th intercostal space in the anterior axillary line

E

points forwards and to the left

Question 5 of 5

Concerning the external features of the heart

(Select all that apply)
A

running in relation to the posterior interventricular sulcus is the great cardiac vein

B

running in relation to the anterior interventricular sulcus is the middle cardiac vein

C

the superior vena cava enters the right atrium at the level of the righ first costal cartilage

D

the superior vena cava enters the right atrium at the level of the right third costal cartilage

E

the marginal branch of the right coronary artery runs in relation to the inferior border of the heart
