Pelvic Limb (Canine, Feline, Equine, Ox) Flashcards
What are the components of the reciprocal apparatus in equine? Where are they located?
- Peroneus tertius (cranial aspect of metatarsal III)
- Superficial digital flexor (caudal aspect of metatarsal (III)
- Gastrocnemius (caudal aspect of metatarsal III)
What are the components of the Suspensory Apparatus or Passive Stay Apparatus?
- Interosseus (suspensory ligament)
- Extensor branches of interosseus
- Proximal sesamoid bones
- Sesamoidean ligaments (straight, oblique, cruciate)
- Superficial digital Flexor with flexor manica
- Deep digital Flexor
The _________ is located between the DDF and navicular bone in the equine?
Navicular bursa
What two joints in the equine move in unison (flex or extend) as part of the reciprocal apparatus?
Stifle and hock (tibiotarsal or tarsocrural joint)
Which joint in the equine pelvic limb has the most movement and the largest synovial cavity?
Tibiotarsal or tarsocrural joint
Which joint may connect with the tarsometatarsal joint in the equine?
Distal intertarsal joint
The proximal intertarsal joint in the equine is continuous with the __________ joint.
Tibiotarsal
Which two synovial spaces are interconnected in the equine stifle joint? Why is this important to consider?
The femoropatellar and medial femorotibial spaces; infection and injections will spread between the two
The lateral femorotibial synovial space is connected to the medial femorotibial space in the equine. T or F?
False: it is separate from all spaces
What are the trochanter on the femur of the equine called and which muscles attach to them?
Greater trochanter (cranial and caudal parts)- Middle and Deep gluteal Lesser trochanter- Iliopsoas m. Third trochanter-Superficial gluteal
Which three muscles insert on the trochanteric fossa of the femur?
Gemelli
External obturator
Internal obturator
The gemelli, quadratus femoris, external obturator, and internal obturator muscles do what to the pelvic limb?
Rotate it laterally
Which muscle rotates the pelvic limb medially?
Middle Gluteal m.
Whirlbone/whirlbone is caused by the inflammation of what in the equine? What can this result in?
Trochanteric bursa; Lameness
Where is the trochanteric bursa located on the equine?
Between the tendon of the middle gluteal m. and cranial part of greater trochanter
Which ligament in the equine prevents it from kicking to the side? What is this ligament deep to?
Accessory ligament of the femoral head; transverse acetabular ligament
Which tendon gives rise to the accessory ligament of the femoral head in the equine?
The prepubic tendon
Which trochanter of the femur is absent in ruminants?
Third Trochanter
The ______________ is on the tibia of horse, but on the fibula of ruminants and carnivores.
Lateral malleolus
The ___________ passes over the sustentaculum tali bone and its tendon meets with the ________ on the proximal caudal aspect of the metatarsal III bone.
lateral DDF m; medial DDF tendon
What is the suspensory apparatus preventing in the equine?
Hyperextension of the fetlock joint
Which part of the femur in the equine serves as the locking part of the patellar locking mechanism?
Medial trochlear ridge
Which muscls is most commonly used in the equine for an intramuscular injection?
Semimembranosus
What is located between the superficial digital flexor tendon and point of the hock?
Subtendinous calcaneal bursa
Which muscle is responsible for flexing the stifle extending the tarsus, and flexing the digits? What about just extending the tarsus and flexing the digits?
Superficial digital flexor
Deep digital flexor
The popliteus muscle has a tendon that originates from the _________ and contains a __________. What does this muscle do?
lateral condyle of femur; popliteal sesamoid bone; flex stifle
