Pelvic Limb Musculature Flashcards
The superficial gluteal in the horse is big, what osteology structure is big because of this?
3rd trochanter
Which bursa in ruminants may become inflamed due to laying in concrete excessively?
Bicipital bursa
What is the ligament analogous to the canine sacrotuberous ligament?
Sacrosciatic ligament
What artery and nerve pass through the greater sciatic foramen?
cranial gluteal a
sciatic n
In ruminants, the caudal gluteal artery passes through the ____________ sciatic foramen
lesser
In equine, which muscle gives off the medial cunean tendon?
Cranial tibial
Where does the cunean tendon insert?
Tarsal bones 1 and 2
Describe the location of the fibularis tertius in relation to the digital extensor
It is deep to the long digital extensor
How can you determine if there is a rupture of the fibularis tertius in horses?
By flexing the stifle and manually extending the hock
Capped hocks means which bursa is inflamed?
synovial bursa in the hock
List muscles involved in hip extension
- middle gluteal and hamstrings (b. femoris, semit and semimemb.)
The popliteus is involved in stifle (flexion/extension)
flexion
The gracilis, pectineus and adductor are involved in thigh ___________
adduction
What muscles are involved in thigh abduction?
superficial/middle/deep gluteal
what prevents flexion of the hip joint?
Gluteal muscles
The patellar locking mechanism prevents what action of the stifle?
flexion
Describe how the patella locks in place
up (quadratus femoris) and medial rotation (vastus medialis/gracilis)
When the patella is pulled proximally and laterally, what happens in the mechanism?
unlock the patella
Which structure of the patella is locked over the medial trochlea?
parapatellar cartilage
Which 2 patellar ligaments hold in place the patella?
medial and middle patellar
What opposes the weight that would flex the hock if nothing were there?
The SDFT
What is the name of the mechanism that forces the hock to flex and extend with stifle in unison?
reciprocal mechanism
