distal intertarsal joint
orange joint?
tarsometatarsal joints
in most species, what joint of the hock is responsible for most movement
talocrural joint
— apical hinge joint
what are the three synovial compartments of the hock
- tarsocrural and proximal intertarsal joints
- lateraldorsal pouch
- mediodorsal pouch
- medioplantar pouch
- lateral plantar pouch - Distal intertarsal joint
- Tarsometatarsal joint
what compartment of the hock is shown in pink
tarsocrural and proximal intertarsal joints
what compartment of the hock is shown in light blue
distal intertarsal joint
what compartment of the hock is shown in dark blue
tarsometatarsal joint
what bones compose the caudal compartment of the leg, hock and pes
Leg : tibia and fibula
Hock : tarsals and metatarsals
Pes : metatarsals, phalanges
what are the caudal leg muscles
- Gastrocnemius
- popliteus
- Flexor digitorum superficialis
- Flexor digitorum profundii
- Flx dig. lateralis
- Flx dig. medialis
- tibialis caudalis

what muscle is in yellow
flexor digitorum superficialis
what muscle is in dark green
tibialis caudalis
what muscle is in dark blue
flexor digitorum medialis
what muscle is in redish pink
flexor digitorum profundii
what muscles make up the common calcaneal tendon
superficial flexor (yellow)
gastrocnemius (blue)
what is blue arrow pointing to
tuber calcaeni
attachment for calcaneal tendon
what arrow identifies the head of the talus?
yellow arrow
head of tarsus articulates w/ central tarsal
which arrow poitns to the trochlea of the talus?
green arrow
trochlea articulates w/ central tarsal
what arrow is pointing to the head (distal end) of the calcaneus
pink
head of calcaneus articulates w/ the 4th tarsal
what does the black arrow point to
sustentaculum tail
what do the green and yellow arrows depict
green: proximal seasamoid bones
yellow: dorsal seasamoid bones
in most mammals, the talar head only articulates with the _____ bone
central bone
in artiodactyls, the talar head expands to form a double pulley astraglus where the talus articulates with the _____ and ______
talus articulates w/ the central bone and 4th tarsal
