TOPIC 31A. Statics of the hindlimbs in horses, the phases of the step on the distal end of the hindlimb Flashcards
What manner does the HL function in
catapult system, providing propulsive force
difference to FL
bears less body weight, more angled
how does it have reciprocal apparatus
stifle infront
hock behind
what is mechanisms of movement controlled by
m peroneus tertius (tendinous) and SDF (common calcaneal tendon)
if stifle is locked ..
so is the hock
what helps in locking the HL
patellar loop
what does the contraction of m rectus femoris do
pulls the patella up over trochlea of femus to supratrochlear fossa
what ligaments are hooked over tuberculum trochlea ossis femoris
medial and intermedial patellar ligaments
Why is there is no accessory ligament of SDF in HL
Because of tuber calcanea and galea calcanea
trotting
2 beat gait
simple diagonal rhythm
what step length is trotting
2-2.3m
what speed is trotting
14-18km/hr
what limbs are syncd in trotting
LH - RF and RH- LF
in fast trot
the thrust phase is shorter than the swing
in the slow trot
the swing phase is shorter than the thrust
