Lab 13: Fresh hindlimb Flashcards
insertion of cunean tendon
T1&2
medial branch of the tendon of tibialis cranialis is known as:
cunean tendon
under what clinical circumstance is cunean tendon cut?
to relieve a chronic bursitis
what is the “reciprocal mechanism”?
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.
Components of the common calcanean tendon
Tendons of:
- gastrocnemius
- superficial digital flexor
- gracilis
- semitendinosus
- caudal division of biceps femoris
where do gastrocnemius tendons insert?
tuber calcaneus
What structures pass through the flexor canal?
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
what is the tarsal sheath? What is its function?
a synovial sheath surrounding the deep digital flexor. Protects m. from damage during physical movement
origin and insertion of accessory (check) ligament
O: tarsal joint capsule
I: deep flexor tendon
Why is the interosseus/suspensory ligament important?
Important part of the stay apparatus. It is a muscle developmentally, but is entirely tendinous in the adult.
name the 4 tarsal joints of the hock
1) tibiotarsal
2) proximal intertarsal
3) distal intertarsal
4) tarsometatarsal
tibiotarsal joint is between:
tibia and trochlea of the talus
proximal intertarsal joint is between:
talus/calcanues and central/4th tarsal bones
distal intertarsal joint is between:
central tarsal bone and T1&2/T3
tarsometatarsal joint is between:
distal row of tarsal bones and metatarsal bones
Which joint cavities communicate with eachother in the tarsus?
tarsocrural and proximal intertarsal joint cavities
Which joint cavities do NOT communicate with each other in the tarsus?
distal intertarsal and tarsometatarsal joints
what is a pouch? How can they be used clinically?
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.
T or F: all 3 joint pouches in the hindlimb communicate with each other and with the tarsocrural joint space
True
Name the 3 pouches of the hindlimb
1) dorsal pouch of the tarsocrural joint
2) medioplantar pouch of the tarsocrural joint
3) lateroplantar pouch of the tarsocrural joint
origin and insertion of long plantar ligament
O: calcaneus
I: fourth tarsal and metatarsal bones
where is dorsal pouch of the tarsocrural joint located?
between peroneus tertius and medial malleolus of the tibia
Where is the medioplantar pouch of the tarsocrural joint located?
on medial side between the tibia and tarsal sheath just proximal to the sustentaculum
where is the lateroplantar pouch of the tarsocrural joint located?
between the lateral malleolus and calcaneus.
In which joint does most of the motion of the hock occur in?
tibiotarsal joint
OCD stands for
osteochondrotis
