Q

The thoracic limb is connected to the body via

A

extrinsic muscles (synsarcosis)

2
Q

Two phase of locomotion

A
  • Stance phase

- Swing phase

3
Q

Stance phase

A

Time the foot contacts the ground

  • Braking
  • propulsion
  • weight bearing
4
Q

Swing phase

A

time limb is propelled through the air

5
Q

What is the major extensor of the elbow

A

triceps brachii

6
Q

____% of the weight of the animals is transferred to the thoracic limb during the stance phase

A

60

7
Q

The weight of the head, neck, and cranial aspect of the trunk is transferred to the thoracic limb via

A

serratus ventralis

Pectoral mm

8
Q

Intrinsic muscles of the thoracic limb

A

Muscles within the limb itself; both attachments of the muscle will be to bones of the thoracic limb

9
Q

The tendon of the deep digital flexor muscle is within

A

the carpal canal

10
Q

Boundaries of the carpal canal

A

doral border - palmar carpal ligament
lateral border - accessory carpal bone
palmar border - flexor retinaculum

11
Q

Knuckling over of carpus

A
  • Animal is having trouble extending the carpus
  • Extensors of the carpus must be affected
  • Extensor muscles of the carpus are supplied by the radial nerve
12
Q

Rigid extension of the elbow

A

-Overstimulation of the triceps brachii muscle must be occurring (localized tatnus)
