what is another name for the tarsus

hock

1

what is the relatively immovable joint between the sacrum and ilium?

sacroiliac joint

1

what is the sacrotuberous ligament?

band of connective tissue from the tuber ischiaticum to sacrum in the dog, NOT THE CAT

1

What is the ligament from the fovea capitis to the acetabular fossa?

ligament of the head of the femur (formerly round ligament of the femur)

1

What articulates to form the hip joint?

acetabulum (os coxae) & head of femur

1

What are the fibrocartilagenous discs between condyles of the femur and tibia?

Medial and lateral menisci

1

How are cruciate ligaments named?

for their attachment to the tibia

1

Which collateral ligament attaches to a meniscus?

medial

1

List the sesamoid bones of the stifle

Patella, 2 in head of gastrocnemius muscle (fabellae) & one in popliteal tendon

1

List the joints of the hock

Tibiotarsal, tarsocrural or talocrural joint
Proximal intertarsal joint (PIT)
Distal intertarsal joint (DIT)
Tarsometatarsal joint (TMt)

2

In what domestic species is the exact configuration of the tarsus clinically most important?

horse

2

Define perineum

Body wall closing the pelvic outlet around the terminations of the digestive & urogenital tracts

3

what is the ischiorectal fossa?

Depression lateral to the anus filled with fat

4

What makes up the pelvic diaphragm?

Coccygeus and levator ani muscles

5

how do the pelvic diaphragm muscles relate to each other?

Coccygeus = more lateral than the levator ani & the levator ani = deep & caudal to the coccygeus m.

6

What is the perineal body?

Fibrous & muscular tissue uniting the anal canal and vagina or bulb of penis

7

Where does the iliopsoas muscle insert?

lesser trochanter of the femur

8

what is the function of the iliopsoas muscle?

major flexor of the hip

9

what are the extensors of the stifle and what innervates them?

cranial thigh muscles (quadriceps) and femoral nerve 

10

what is the action and innervation of the medial thigh muscles?

adduction, obturator nerve (pectineus, gracilis and adductor mm)

11

list the hamstrings muscles from lateral to medial

Biceps femoris, semitendinosus, semimembranosus

12

What are the insertions of the superficial digital flexor and deep digital flexor in the dogs pelvic limb?

SDF = middle phalanges; DDF = distal phalanges

13

what are the actions of the crural muscles? innervation?

craniolateral: extensors of the digits and flexors of the tarsus, innervated by the common fibular nerve ; caudal:flexors of the digits and extensors of the tarsus, innervated by tibial nerve

14

what is the composite tendon inserting on the calcaneus? what are its main components?

common calcanean tendon; SDF and gastrocnemius

15

What is required to evaluate coxofemoral luxation radiographically?

2 views are needed to ascertain direction of luxation; craniodorsal is most common

16

In young dogs, what bone has a growth plate which looks like a fracture?

Tibial tuberosity

17

what does a skyline/tangential view of the stifle show?

depth of trochlear groove, patella and femoropatellar joint space

18

on the mediolateral projection of the stifle what is the radiolucent density seen in the triangle formed by the femur, tibia, and distal patellar ligament?

subpatellar fat

19

what are the four sesamoid bones that should not be mistaken for fracture fragments in radiographs of the stifle joint?

patella, 2 of gastrocnemius muscle and one in popliteal tendon

20

how is the lateral side of the DP view of the tarsus easily identified?

fourth tarsal bone is 2-story: on lateral aspect
