what is another name for the tarsus
what is the relatively immovable joint between the sacrum and ilium?
what is the sacrotuberous ligament?
band of connective tissue from the tuber ischiaticum to sacrum in the dog, NOT THE CAT
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)
What articulates to form the hip joint?
acetabulum (os coxae) & head of femur
What are the fibrocartilagenous discs between condyles of the femur and tibia?
Medial and lateral menisci
How are cruciate ligaments named?
for their attachment to the tibia
Which collateral ligament attaches to a meniscus?
List the sesamoid bones of the stifle
Patella, 2 in head of gastrocnemius muscle (fabellae) & one in popliteal tendon
List the joints of the hock
Tibiotarsal, tarsocrural or talocrural joint
Proximal intertarsal joint (PIT)
Distal intertarsal joint (DIT)
Tarsometatarsal joint (TMt)
In what domestic species is the exact configuration of the tarsus clinically most important?
Body wall closing the pelvic outlet around the terminations of the digestive & urogenital tracts
what is the ischiorectal fossa?
Depression lateral to the anus filled with fat
What makes up the pelvic diaphragm?
Coccygeus and levator ani muscles
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.
What is the perineal body?
Fibrous & muscular tissue uniting the anal canal and vagina or bulb of penis
Where does the iliopsoas muscle insert?
lesser trochanter of the femur
what is the function of the iliopsoas muscle?
major flexor of the hip
what are the extensors of the stifle and what innervates them?
cranial thigh muscles (quadriceps) and femoral nerve
what is the action and innervation of the medial thigh muscles?
adduction, obturator nerve (pectineus, gracilis and adductor mm)
list the hamstrings muscles from lateral to medial
Biceps femoris, semitendinosus, semimembranosus
What are the insertions of the superficial digital flexor and deep digital flexor in the dogs pelvic limb?
SDF = middle phalanges; DDF = distal phalanges
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
what is the composite tendon inserting on the calcaneus? what are its main components?
common calcanean tendon; SDF and gastrocnemius
What is required to evaluate coxofemoral luxation radiographically?
2 views are needed to ascertain direction of luxation; craniodorsal is most common
In young dogs, what bone has a growth plate which looks like a fracture?
what does a skyline/tangential view of the stifle show?
depth of trochlear groove, patella and femoropatellar joint space
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?
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
