6

What muscles make up the common calcanean tendon?

Biceps Femoris
Semitendinosus
Gracilis
Gastrocnemis
Superficial Digital Flexor

7

What structure is found beneath the infraspinatus muscle?

Subtendinous synovial bursa

8

What is the caudal border of the Femoral Triangle? What is this muscles action?

Pectineus muscle: adducts the limb

9

Which of the following muscles adducts the limb, flexes the stifle, and extends the hip?

A. Adductor
B. Gracilis
C. Sartorius
D. Pectineus

B Gracilis muscle

10

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

11

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

12

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

13

Which muscles does the crural extensor retinaculum hold down?

cranial tibial muscle and the long digital extensor muscle

14

What are the hypaxial muscles?

Longus capitis
Longus Coli
Scalenus
Serratus ventralis- cervicis and thoracis
Serratus dorsalis - cranialis and caudalis
External intercostal muscles
Internal intercostal muscles

15

Which direction does the muscle fibers of the external intercostal muscles run?

caudoventrally

16

What are the inspiratory muscles?

Diaphragm
External Intercostal muscles
Serratus Dorsalis cranialis
Scalenus
Rectus Thoracis

17

Name the three main systems of the expaxial muscles and what they are divided into.

Iliocostalis System (lumborum, thoracis)

Longissiumus System (lumborum, cervicis, capitis)

Transversospinalis System
-Splenius
-Semispinalis Capitis (Complexus, and Biventer cervicis)

18

What are the expiratory muscles?

Internal intercostals
Serratus dorsalis caudalis
Transversus thoracis
Abdominal muscles

19

Which ligament is the continuation of the Supraspinous ligament and can be found from T1 to C2?

Nuchal ligament

20

What is known as the "hooks" in bovine?

Tuber coxae

21

What are the boundaries of the pelvic inlet?

Lateral: arcuate line of the ilium
ventral: pecten of the pubis
dorsal: promontory of the sacrum

22

What are the boundaries of the pelvic outlet?

Lateral: Sacrotuberous ligament
ventral: Ischiatic arch
dorsal: first caudal vertebra

23

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

24

A rupture of which ligament allows the forward movement of the tibia (tibia moves cranially) while the femur stays in place?

Cranial cruciate ligament

25

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

26

What tendon gives rise to the Accessory ligament of the femoral head?

Prepubic Tendon

27

True/False: The Third trochanter is prominent in ruminants and absent in horses.

False. It is prominent in horses and absent in ruminants

28

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.

Tuber Ischia

30
