Lab 13: Fresh hindlimb

Question 0

insertion of cunean tendon

Answer 0

T1&2

Question 1

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

Answer 1

cunean tendon

Question 2

under what clinical circumstance is cunean tendon cut?

Answer 2

to relieve a chronic bursitis

Question 3

what is the “reciprocal mechanism”?

Answer 3

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.

Question 4

Components of the common calcanean tendon

Answer 4

Tendons of:

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

Question 5

where do gastrocnemius tendons insert?

Answer 5

tuber calcaneus

Question 6

What structures pass through the flexor canal?

Answer 6

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

Question 7

what is the tarsal sheath? What is its function?

Answer 7

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

Question 8

origin and insertion of accessory (check) ligament

Answer 8

O: tarsal joint capsule
I: deep flexor tendon

Question 9

Why is the interosseus/suspensory ligament important?

Answer 9

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

Question 10

name the 4 tarsal joints of the hock

Answer 10

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

Question 11

tibiotarsal joint is between:

Answer 11

tibia and trochlea of the talus

Question 12

proximal intertarsal joint is between:

Answer 12

talus/calcanues and central/4th tarsal bones

Question 13

distal intertarsal joint is between:

Answer 13

central tarsal bone and T1&2/T3

Question 14

tarsometatarsal joint is between:

Answer 14

distal row of tarsal bones and metatarsal bones

Question 15

Which joint cavities communicate with eachother in the tarsus?

Answer 15

tarsocrural and proximal intertarsal joint cavities

Question 16

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

Answer 16

distal intertarsal and tarsometatarsal joints

Question 17

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

Answer 17

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.

Question 18

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

Answer 18

True

Question 19

Name the 3 pouches of the hindlimb

Answer 19

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

Question 20

origin and insertion of long plantar ligament

Answer 20

O: calcaneus
I: fourth tarsal and metatarsal bones

Question 21

where is dorsal pouch of the tarsocrural joint located?

Answer 21

between peroneus tertius and medial malleolus of the tibia

Question 22

Where is the medioplantar pouch of the tarsocrural joint located?

Answer 22

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

Question 23

where is the lateroplantar pouch of the tarsocrural joint located?

Answer 23

between the lateral malleolus and calcaneus.

Question 24

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

Answer 24

tibiotarsal joint

Question 25

OCD stands for

Answer 25

osteochondrotis
