Pelvic Symphysis
What does the pelvic bone articulate with dorsally?
Sacrum
What three bones make up the pelvis
Ilium, Ischium, Pubis
What is the purpose of the Greater sciatic notch of the pelvis?
Sciatic nerve passes here on the way to hindlimb
What is the two branches of the pubis called?
Cranial portion is the acetabular and the caudal portion is Symphysial
What is the purpose of the obturator foramen of the pelvis
opening in pelvic floor through which the obturator nerves emerges
What is the purpose of the acetabulum of the pelvis?
Deep articular cup for the femur
always lateral
all 3 hip bones contribute
what does the auricular articular surface of the pelvis articulate with?
the sacrum
What is considered the strongest of the long bones?
Femur
What is the purpose of the head of the femur?
Fits in the acetabulum
Always medial
What attaches to the fovea of the femur?
Intracapsular ligament attaches
Why is the intracapsular ligament important?
keeps hip joint from dislocating
What muscle attaches to the Greater trochanter of the femur
Bulk of the gluteal muscle
(always lateral)
What inserts at the lesser trochanter of the femur?
iliopsoas muscle
What inserts at the Trochanteric fossa of the femur
rotator muscles
what does the trochlea of the femur articulate with?
patella
What originates at the supracondylar tuberosities of the femur
superficial digital flexor
What does the lateral and medial condyles of the femur articulate with?
tibia
The patella (kneecap) is developed within the insertion of what?
quadriceps femoris
The extensor fossa of the femur is the origin of what two muscles?
long digital extensor
peroneus tertius muscle
What originates at the fossa for popliteus of the femur?
popliteus muscle
What is the other name for the tibia and fibula?
Crus
Which bone (tibia or fibula) is larger and always runs medial
tibia
fibula is lateral
What separates the tibia and fibula in dogs?
interosseous space
What does the intercondylar eminence of the tibia separte?
lateral and medial condyles
What is the prominent landmark of the tibia
tibial tuberosity
What articulates with the lateral and medial condyles of the tibia?
femur
What does the cochlea of the tibia articulate with?
trochlea of talus (tarsal bone)
How many tiers of tarsal bones are there
3
What is the other two names for the taral bones?
Hindpaw or “Pes”
What tarsal bones are in the proximal tier?
Talus and Calcaneus
What tarsal bone is in the middle tier?
Central tarsal bone
What tarsal bones are in the distal teir?
1-4 (medial to lateral)
4th tarsal bone enters middle tier as well
What is important about the sustentaculum tali of the calcaneus
it supports the deep digital flexor tendon
What part of the calcaneus is the point of the hock?
Calcanean tuber
what attaches to the calcaneal tuber (of the calcaneus)
the common calcanean tendon
Is the talus medial or lateral?
medial
Are metatarsal bones longer or shorter than metacarpal bones?
longer
Metacarpal I is usually ________ in dogs
rudimentary (non existant)
Few breeds consistently have what in the hindlimb?
Dew Claws
