1

Named pleura

costal, diaphragmatic, mediastinal, visceral

2

costal pleura

lines ribs

3

diaphragmatic

lines diaphragm

4

mediastinal pleura

lines mediastinum

5

visceral pleura

touches lungs

6

pericardium

Mediastinal parietal pleura, fibrous pericardium, parietal pericardium, visceral pericardium

7

surgeons pericardium

aka the pericardium: parietal pericardium, fibrous pericardium, mediastinal parietal pleura

8

cupula pleura

on both sides of cr mediastinum; where costal pleura reflects back and becomes mediastinal pleura; extends cr to 1st rib on R side

9

clinical significance cupula pleura

extends beyond 1st rib on R side so if horse injures itself here then it can -> pneumothorax

10

costodiaphragmatic recess

cd to basal border of lung where costal and diaphragmatic pleura rest against each other

11

clinical significance costal diaphragmatic recess

try to enter abdominal cavity during expiration where this space is bigger

12

Lobation of equine lung

less distinct than dogs but R and L cr and cd lobes and R accessory lobe around cd vc; lobes connected by CT after tracheal bifurcation at 5th rib or IC space

13

location of cardiac notch

divides lung lobes crly and cdly

14

L cardiac notch

between 3rd and 6th rib

15

R cardiac notch

between 3rd and 4th IC space

16

Line of pleural reflection

divides pleural and peritoneal cavity; represents where costal parietal pleura reflects back to become diaphragmatic parietal pleura; closely follows attachements of diaphragm

17

line of pleural reflection landmarsk

starts 8-9th costal cartilage, curves dorsocaudally along rib cage to 18th rib; reflects cranially to end at 17th IC space

18

boundaries of basal border of the lung

triangle shape
1. one side dorsal along back v to epaxial muscles
2. one side line drawn from olecranon to junction scapular cartilage with scapula
3. 6, 11 ,16: 6th costochondral junction, middle 11th rib, dorsal extend 16th rib

19

where to auscult lung field in relation to basal border of lung

3-4cm cr to this line

20

chambers of the heart

L atria, L ventricle, R atria, R ventricle; separated by AV valves

21

papillary muscles

muscles located in ventricles heart attach to cusps of AV valves via chord tendinae and contract preventing inversion or prolapse of these valves on systole

22

chordae tendinae

attach papillary muscles to AV vales

23

septomarginal bands

help transmit electrical signals down purkinje fibers

24

atrial surface of the heart

R side, subsinusosal IV groove

25

Subsinusosal IV groove

on atrial surface (R side) of heart; contains R coronary artery, middle cardiac vein

26

Auricular surface of the heart

L side; Paraconal IV groove

27

paraconal IV groove

on auricular surface (L side) of heart; contains L coronary artery and great cardiac vein

28

sternopericardiac ligament

v large in horse; anchors fibrous pericardium to sternum

29

Cardiac embryonic remnants

ligamentum arteriosum and fossa ovalis

30

ligamentum arteriosum

remnant of ductus arterioles; L recurrent laryngeal nerve wrap around ligament arteriosum
