Pleura

Question 1

Pericardium

Answer 1

fibroserous covering of the heart; thin but strong, 3 inseparable parts (serous/fibrous/pericardial mediastinal pleura)

Question 2

Parietal fibrous layer (heart)

Answer 2

layer directly underneath the pericardial mediastinal pleura; fibrous; inseparable from the serous, external to serous

Question 3

Parietal serous layer (heart)

Answer 3

closed sac, envelopes most of the heart; shiny, internal to fibrous layer, inseparable

Question 4

Visceral (epicardium)

Answer 4

pleura that is tightly adhered to the heart; separated from the parietal pleura by the pericardial cavity

Question 5

Phrenicopericardial ligament

Answer 5

continuation of the fibrous pericardium to the sternum and the diaphragm; located in the ventral mediastinum along with a variable amount of fat

Question 6

Pleurae

Answer 6

serous membranes that cover the lungs and line the walls of the thorax; form left and right sacs that enclose the parietal cavities; each consists of visceral and parietal parts

Question 7

Parietal pleura

Answer 7

attached to the thoracic wall by the endothoracic fascia; divided into costal, diaphragmatic, mediastinal

Question 8

Costal pleura

Answer 8

covers the inner surface of the ribs and their associated intercostal and transversus thoracis muscles

Question 9

Mediastinal pleura

Answer 9

layers that covers the sides of the partition between the two pleural cavities

Question 10

Mediastinum

Answer 10

includes 2 mediastinal pleura and the space between them; enclosed within are the thymus, lymph nodes, heart, aorta, trachea, esophagus, vagus nerves and other nerves/vessels; divided into 3 parts

Question 11

Diaphragmatic pleura

Answer 11

covers the cranial surface of the diaphragm

Question 12

Visceral (pulmonary) pleura

Answer 12

closely attaches to the surfaces of the lungs

Question 13

Plica vena cavae

Answer 13

loose fold of pleura derived from the right caudal mediastinal portion of the pleural sac that surrounds the caudal vena cava

Question 14

Root of the lung

Answer 14

composed of pleura and bronchi, vessels, nerves entering the lung; here mediastinal parietal pleura is continuous with pulmonary pleura

Question 15

Pulmonary ligament

Answer 15

caudal to the hilus, connection of mediastinal parietal pleura and pulmonary pleura forms a free border; between the caudal lobe of the lung and mediastinum at the level of the esophagus

Question 16

Cranial mediastinum

Answer 16

cranial to heart

Question 17

Middle mediastinum

Answer 17

contains the heart

Question 18

Caudal mediastinum

Answer 18

caudal to heart, ends at diaphragm

Question 19

Pericardial mediastinal pleura

Answer 19

portion covering the heart
