Q

Ligaments btwn sucessive vertebral arches

A

Interarcuate ligament

18
Q

Ligaments btwn sucessive spinous processes

A

Interspinous ligaments

19
Q

Ligaments btwn the heads of ribs

A

Intercapital ligaments

20
Q

Ligaments btwn transverse processes

A

Intertransverse ligaments

21
Q

State the position of intercapital ligaments in regards to vertebral disc and longitudinal discs

A

Above intervertebral discs and under the dorsal longitudinal ligament

22
Q

Group of muscles that lie above transverse processes

State its movement on the spine

A

Epaxial muscles; extend the spine

23
Q

Group of muscles that lie under transverse processes

State its movement on the spine

A

Hypaxial muscles; flex the spine

24
Q

Name the three groups of epaxial muscles

A

Transversospinalis, longissimus, and iliocostalis groups

25
Q

Joints btwn the ribs and cranial part of respective vertebral bodies

A

Costovertebral articulations

26
Q

State how costovertebral articulations are formed

A

The head of rib connects the cranial costal facet of its respective vertebra but also the caudal costal facet of the previous vertebra.

27
Q

Joints btwn the ribs and transverse processes

A

Costotransverse articulations

28
Q

State how costotransverse articulations are formed

A

The tubercle of rib articulates with the transverse processes

29
Q

States the five structures of ribs

A

head, tubercle, neck, angle, and body

30
Q

Connection btwn. ribs and costal cartilage

A

Costochondral junction

31
Q

Give an example of muscle that attaches to the angle of ribs

A

Iliocostalis muscle

32
Q

Give an example of muscle that attaches to the shaft of ribs

A

Intercostal muscle

33
Q

State how the shape of rib’s shaft may be different btwn. carnivores and ruminants

A

Carnivores - more cylindrical

Ruminants - more flattened

34
Q

Vascular bundle lies on which side of rib

A

Caudal surface

35
Q

What are “true” ribs?

A

Ribs articulate directly with the sternum at intersternebral cartilage

36
Q

What are “false” ribs?

A

Ribs joins the cartilage of the next most cranial rib

37
Q

What is a “floating” rib?

A

Rib is unconnected to the sternum

38
Q

An arrangement formed by “false” ribs

A

Costal arch

39
Q

State the function of intercapital ligaments

A

They help to prevent disc prolapse/ extruded material

40
Q

States the three main structures of ribs

A

Manubrium (cranial), body (sternebrae and intersternebral cartilages), and xiphoid

41
Q

How can xiphoid help to support the cranial abdominal floor?

A

It forms an attachment with linea alba

42
Q

State the interspecies variation of sternum (dogs & cats, herbivores, horse, and ruminants)

A

Dogs and cats - rodlike manubrium; cylindrical sterebrae
Herbivores - latterally compressed manubrium
Horse - extensive cartilage
Ruminants - wide and flat sternum
