Lecture 11 2/16/24 Flashcards
Which muscles make up the lateral muscles of the hip in the equine?
-superficial gluteal m.
-middle gluteal m.
-accessory gluteal m.
-deep gluteal m.
Which structure is associated with the accessory gluteal m.?
trochanteric bursa
What are the three patellar ligaments associated with the quadriceps femoris m. in the equine?
-lateral patellar lig.
-intermediate patellar lig.
-medial patellar lig.
What are the three parts of the biceps femoris in the equine?
-proximal/cranial
-middle
-distal/caudal
How does the sartorius m. differ between the equine and the canine?
only one undivided belly in the equine
How does the gracilis m. differ between the equine and the canine?
does not contribute to the common calcanean tendon in the equine
How does the pectineus m. differ between the equine and the canine?
perforated by the accessory lig. of the femur, which comes off the pre-pubic tendon
What are the characteristics of the cranial tibial muscle in the equine?
-deepest muscle in the craniolateral crus m. group
-inserts via dorsal and medial tendon branches
-medial branch = cunean tendon
What are the characteristics of the long digital extensor in the equine?
-originates with the peroneus tertius
-joined by lateral digital extensor below the hock
What are the characteristics of the peroneus tertius in the equine?
-entirely tendinous
-lies between cranial tibial and long digital extensor m.
-inserts via dorsal and lateral branches
-perforated by cranial tibial m.
What are the characteristics of the soleus m.?
-from the head of fibula
-inserts on tendon of gastrocnemius
-technically contributes to common calcanean tendon
What are the characteristics of the superficial digital flexor in the equine?
almost entirely tendinous
What are the parts of the deep digital flexor in the equine?
-lateral digital flexor
-medial digital flexor
-accessory ligament of the DDF/distal check ligament
Which tendons are contained in the crural extensor retinacula?
-long digital extensor
-cranial tibial
-peroneus tertius
Which tendon is contained in the tarsal extensor retinacula?
long digital extensor
Which tendons are contained in the metatarsal extensor retinacula?
-long digital extensor
-lateral digital extensor
Where is the trochanteric bursa located?
between the accessory gluteal muscle and the cranial part of the greater trochanter
Where are the calcanean bursae located?
-subtendinous is between SDF and gastrocnemius mm.
-subcutaneous is within superficial fascia over point of the hock
What is unique about the subcutaneous calcanean bursa?
it is acquired
Where is the cunean bursa located?
deep to the medial branch of the cranial tibial m.
What are the characteristics of the navicular bursae?
-found on both fore- and hindlimbs
-cushions DDF tendon from navicular bone
