pecten
The pectineus muscle attaches to the?
iliopubic eminence
the concavity articulating with the femoral head
Acetabulum
Formed by the fusion of the ilium, ischium, pubic and acetabular bones
Acetabulum
The ligament of the ? attaches to the fossa in the acetabulum
Head of femur
This part of acetabulum articulates with the head of the femur
lunate surface
large opening in the floor of the os coxae
Obturator foramen
is where the right and left sides of the pelvis (hip bones) meet, connecting the pubic and ischial bones from both sides.
pelvic symphysis
the heaviest bone in the body articulating proximally with the hip bone (forming the hip joint) and distally with the tibia and patella (forming the stifle joint)
Femur (thigh bone) -
Femur (thigh bone) is the heaviest bone in the body articulating proximally with the hip bone forming what joint?
hip joint
Femur (thigh bone) - the heaviest bone in the body articulating distally with the tibia and patella forming what joint?
stifle joint
the smooth process of femur articulating with the acetabulum of the os coxae, forming the hip joint
Head
The caudal head of the femur has a depression called ? , for the round ligament of the femur
fovea
joins the head to the body of the femur
neck
the large prominence lateral to the head of femur
Greater (major, lateral) trochanter
the prominence distal to the head of femur
Lesser (minor, medial) trochanter
depression on the caudal aspect of the femur between the trochanters
Trochanteric fossa
the prominence on the lateral side, distal to the greater trochanter
Third trochanter
the two large prominences articulating with the tibia and the menisci (fibrocartilage discs between femur and tibia)
Medial and lateral condyles
depression on the lateral condyle for attachment of the long digital extensor muscle
Extensor fossa
the groove in the femur articulating with the patella, bounded by two ridges, the medial one being the thicker in all species
Patellar surface or femoral trochlea
the largest sesamoid bone of the body, articulating with the patellar surface of the femur
Patella (knee cap)
What skeletons are the tibia and fibula
Leg skeleton ( crus)
separates the tibia and fibula
Interosseous space
the medially located leg bone
Tibia (shin bone)
the two processes articulating with the corresponding femoral condyles and fibrocartilage discs (menisci)
Lateral and medial condyles
the large proximal cranial process of tibia where muscles and the patellar ligament(s) attach
Tibial tuberosity
the two grooves on tibia, separated by a ridge, articulating with the trochlea of the tibial tarsal bone
Distal articular surface or cochlea
the long, thin caudal leg bone bearing little weight, serving mainly for muscle attachments
Fibula (calf bone)
Fibula (calf bone) articulates distally with?
tibia and the fibular tarsal bone
It is more lateral of the two leg bones
Fibula
the distal end of the fibula
Lateral malleolus
the two (or two 2 1⁄2) rows of bones between the crus and the metatarsal region
“Hock”
In the generalized pattern seen in the hock of carnivores and pig, the distal row consists of?
central, 1st, 2nd, 3rd and 4th tarsal bones
is between the proximal row and the numbered tarsal bones
central tarsal bone
Two story tarsal bone
4th tarsal bone
It doesn’t span the whole tarsus because of the “two story” fourth tarsal bone
Central tarsal bone
the largest bone of the tarsus, located on its dorsomedial side
Talus (ankle bone) or tibial tarsal bone
the second tarsal bone of the proximal row, lateral to the tibial tarsal bone
Calcaneus or fibular tarsal bone
the large process of the fibular tarsal bone serving as a lever arm for the common calcanean tendon
Calcanean tuberosity
the medial “shelf” of the calcaneus
Sustentaculum tali
their pattern is similar to the metacarpus and digits of the thoracic limb
Metatarsal bones and Digit
The proximal row of hock consists of?
talus (tibial) and calcaneus (fibular) tarsal bones
