1

What are the two major parts of a typical vertebra?

Body and arch

2

What is an intervertebral foramen?

Opening between adjacent vertebrae allowing passage of the spinal nn.

3

How do ribs articulate with the thoracic vertebrae?

Head articulates with bodies of contiguous vertebrae and the tubercle articulates with the transverse process of same numbered

4

What is the name of the space between two adjacent ribs?

Intercostal space (ICS)

5

What do the costal cartilages of the last sternal and all asternal ribs form?

Costal arch

6

What are the first and last sternebrae?

Manubrium and xiphoid, respectively

7

What caps the xiphoid process?

Xiphoid cartilage

8

what thoracic vertebrae usually has the most vertically oriented spine?

Anticlinal vertebrae, usually T11 in dog

9

How is inspiration accomplished?

Increased size of thorax decreases pressure = air rushes in

10

What is the main respiratory muscle?

Diaphragm

11

Name the 2 muscles extending between adjacent ribs.

External and internal intercostal mm.

12

What is the opening into the thorax?

Thoracic inlet

13

What forms the thoracic inlet?

1st thoracic vertebra, right and left 1st ribs and sternum

14

What palpable structure is formed by the costal cartilages of the false ribs?

Costal arch

15

What divides the thorax into two spaces?

Mediastinum

16

Where is the heart located in the thoracic cavity?

(2nd) 3rd to (5th) 6th intercostal space (ICS) in the bottom 2/3rds of the cavity

17

Which side of the aorta does the thoracic esophagus normally cross?

Right side of the aortic arch

18

What covers the trachea in the cranial neck?

Only strap muscles (sternohyoideus and sternothyroideus mm)

19

What part of the trachea splits into right and left primary bronchi?

Tracheal biforcation

20

What separates lobes of the lungs?

Interlobar fissures

21

What is the opening between the lobes of the lung where the surgeon's pericardium comes in contact with the thoracic wall?

Cardiac notch

22

What do radiologists call the pulmonary trunk?

Main pulmonary artery/segment, MPA

23

What is the mediastinum?

Space or wall (depending on text read, wall makes parietal work for the pleura) separating the thoracic cavity into 2 cavities and thus, separating the 2 pleural cavities

24

What are the divisions of the mediastinum?

Cranial, middle (contains heart), and caudal (all divided into dorsal and ventral parts)

25

List the parts of the pericardium.

Fibrous pericardium, serous pericardium (visceral and parietal parts)

26

What is located in the pericardial cavity?

scant amount of serous fluid only

27

which side of the heart is part of the pulmonary circulation?

Right side: pulmonary side

28

The left side of the heart is part of what circulation and why?

Systemic circulation, pumps blood to body

29

What side of the heart is the right ventricle on? Left ventricle?

Right: cranial (right, cranial, and left sides); left: caudal

30

What is the vestigial, fetal connection form the pulmonary trunk to the aorta?

Ligamentum arteriosum
