Lecture 28 - Pelvic Limb 5 Flashcards

1
Q

What are the comparative differences in the fibula for horses, pigs, and ruminants

A

horses have great variation as it is vestigial
pigs have a complete separate fibula
ruminants have a distal fibula that forms separate lateral malleolus

Q

why are the dorsomedial and plantarolateral tarsocrural joint pouches commonly used for injection sites

A

they are easily accessed and communicate freely with all pouches

15
Q

the fibularis longus m. is absent in this species

16
Q

this species has one patella ligament

17
Q

the fibularis tertius is part of the

A

reciprocal apparatus

18
Q

stringhalt involves abnormal function of this muscle

A

lateral digital extensor m.

19
Q

the cunean tendon is the dorsomedial insertion of this muscle

A

cranial tibial

20
Q

the patella locks over this trochlear ridge of the femur

21
Q

the meniscofemoral ligament connects this meniscus to the femur

22
Q

why may the fibular be incorrectly classified as fractured on radiographs

A

proximal part is not ossified

23
what is the action of the craniolateral crus muscles
flex tarsus and extend digits
24
T/F: there is a union of the lateral digital extensor and long digital extensor in the mid-crus
TRUE
25
list the crus muscle groups caudally
popliteus SDFT DDFT gastrocnemius
26
the cunean bursa sits between what two structures
cunean tendon and medial collateral ligament
27
what is the action of the caudal crus muscles
extend tarsus and flex digits
28
what is a species difference in the tarsus of swine
4 metatarsals no fused tarsal bones
29
what is a species difference in the tarsus of bovine
fused III and IV metatarsals fused central + IV and II + III tarsals
30
what is a species difference in the tarsus of equine
3rd metatarsal (splint bones II and IV) fused I + II tarsals
