Q

insertion of cunean tendon

A

T1&2

1
Q

medial branch of the tendon of tibialis cranialis is known as:

A

cunean tendon

2
Q

under what clinical circumstance is cunean tendon cut?

A

to relieve a chronic bursitis

3
Q

what is the “reciprocal mechanism”?

A

Mechanism by which stifle and hock joints work in unison, with both joints either flexed or extended at the same time. The superficial digital flexor and peroneus tertius act as a parallelogram over the stifle and hock joints and dictate that the stifle and hock work in unison.

4
Q

Components of the common calcanean tendon

A

Tendons of:

  • gastrocnemius
  • superficial digital flexor
  • gracilis
  • semitendinosus
  • caudal division of biceps femoris
5
Q

where do gastrocnemius tendons insert?

A

tuber calcaneus

6
Q

What structures pass through the flexor canal?

A

1) Deep digital flexor
2) medial and lateral plantar nerves
3) saphenous artery

The flexor canal is analogous to the carpal canal in the forelimb

7
Q

what is the tarsal sheath? What is its function?

A

a synovial sheath surrounding the deep digital flexor. Protects m. from damage during physical movement

8
Q

origin and insertion of accessory (check) ligament

A

O: tarsal joint capsule
I: deep flexor tendon

9
Q

Why is the interosseus/suspensory ligament important?

A

Important part of the stay apparatus. It is a muscle developmentally, but is entirely tendinous in the adult.

10
Q

name the 4 tarsal joints of the hock

A

1) tibiotarsal
2) proximal intertarsal
3) distal intertarsal
4) tarsometatarsal

11
Q

tibiotarsal joint is between:

A

tibia and trochlea of the talus

12
Q

proximal intertarsal joint is between:

A

talus/calcanues and central/4th tarsal bones

13
Q

distal intertarsal joint is between:

A

central tarsal bone and T1&2/T3

14
Q

tarsometatarsal joint is between:

A

distal row of tarsal bones and metatarsal bones

15
Q

Which joint cavities communicate with eachother in the tarsus?

A

tarsocrural and proximal intertarsal joint cavities

16
Q

Which joint cavities do NOT communicate with each other in the tarsus?

A

distal intertarsal and tarsometatarsal joints

17
Q

what is a pouch? How can they be used clinically?

A

an extension of a joint capsule into a region mostly bounded by soft tissue. They are useful sites of injection of a substance into a joint via a pouch.

18
Q

T or F: all 3 joint pouches in the hindlimb communicate with each other and with the tarsocrural joint space

A

True

19
Q

Name the 3 pouches of the hindlimb

A

1) dorsal pouch of the tarsocrural joint
2) medioplantar pouch of the tarsocrural joint
3) lateroplantar pouch of the tarsocrural joint

20
Q

origin and insertion of long plantar ligament

A

O: calcaneus
I: fourth tarsal and metatarsal bones

21
Q

where is dorsal pouch of the tarsocrural joint located?

A

between peroneus tertius and medial malleolus of the tibia

22
Q

Where is the medioplantar pouch of the tarsocrural joint located?

A

on medial side between the tibia and tarsal sheath just proximal to the sustentaculum

23
Q

where is the lateroplantar pouch of the tarsocrural joint located?

A

between the lateral malleolus and calcaneus.

24
Q

In which joint does most of the motion of the hock occur in?

A

tibiotarsal joint

25
Q

OCD stands for

A

osteochondrotis
