D. Rectus Femoris
D. Rectus Femoris
Which muscles are powerful extensors of the stifle?
What are the Small Pelvic Association Muscles?
Which of the following muscles inserts at the intertrochanteric crest of the femur?
A. Internal Obturator
B. Quadratus Femoris
D. External Obturator
B. Quadratus Femoris muscle
Which muscle group is an extensor of the hip and flexors of the stifle?
What muscles make up the common calcanean tendon?
Superficial Digital Flexor
What structure is found beneath the infraspinatus muscle?
Subtendinous synovial bursa
What is the caudal border of the Femoral Triangle? What is this muscles action?
Pectineus muscle: adducts the limb
Which of the following muscles adducts the limb, flexes the stifle, and extends the hip?
B Gracilis muscle
Name all the borders of the Femoral Triangle
Base: abdominal wall and inguinal ligament
Caudal border: Pectineus muscle
Cranial border: caudal belly of the sartorius muscle
Which is the only gluteal muscle that does not insert at the greater trochanter of the femur? Where does it insert, and what is its action?
Superficial Gluteal muscle : inserts at the third trochanter of the femur and it extends the hip and abducts the limb
True/False: The cranial tibial muscle rotates the paw medially so the plantar surface faces laterally.
False: the cranial tibial muscle rotates the paw laterally so the plantar surface faces medially
Which muscles does the crural extensor retinaculum hold down?
cranial tibial muscle and the long digital extensor muscle
What are the hypaxial muscles?
Serratus ventralis- cervicis and thoracis
Serratus dorsalis - cranialis and caudalis
External intercostal muscles
Internal intercostal muscles
Which direction does the muscle fibers of the external intercostal muscles run?
What are the inspiratory muscles?
External Intercostal muscles
Serratus Dorsalis cranialis
Name the three main systems of the expaxial muscles and what they are divided into.
Iliocostalis System (lumborum, thoracis)
Longissiumus System (lumborum, cervicis, capitis)
-Semispinalis Capitis (Complexus, and Biventer cervicis)
What are the expiratory muscles?
Serratus dorsalis caudalis
Which ligament is the continuation of the Supraspinous ligament and can be found from T1 to C2?
What is known as the "hooks" in bovine?
What are the boundaries of the pelvic inlet?
Lateral: arcuate line of the ilium
ventral: pecten of the pubis
dorsal: promontory of the sacrum
What are the boundaries of the pelvic outlet?
Lateral: Sacrotuberous ligament
ventral: Ischiatic arch
dorsal: first caudal vertebra
What ligament is present in equine that limits their range of motion of kicking to the side and makes hip luxation very rare?
Acessory ligament of the femoral head
A rupture of which ligament allows the forward movement of the tibia (tibia moves cranially) while the femur stays in place?
Cranial cruciate ligament
If we have a partial tear, just the gastrocnemius, what will occur? What about a complete rupture?
-There will be a dropped hock and a curled toe if there was a partial tear
-The animal would be flat footed with a dropped hock and lameness if all tendons have ruptured
What tendon gives rise to the Accessory ligament of the femoral head?
True/False: The Third trochanter is prominent in ruminants and absent in horses.
False. It is prominent in horses and absent in ruminants
What muscles are involved in the Reciprocal Apparatus and what is the purpose of this mechanism?
Perioneus Tertius muscle, the Gastrocnemeus muscle, and the SDF. Allows the stifle and the hock to flex and extend together.
What is considered the "Pin Bone" of bovine?
