Proximal Interphalangeal joint is commonly called _______. It is a _____ joint
pastern; saddle joint
Distal Interphalangeal joint is commonly called ____ and is a _____ joint.
coffin; saddle joint
Metacarpophalangeal joint [fetlock] is a _____ hinge joint
compound
what is the purpose of the palmar and distal pouch
easy way to access the joint; injections
Superficial Digital Flexor insertion
Flexor surfaces of proximal and middle
phalanges
Deep Digital Flexor insertion
Flexor surface of the distal phalanx
purpose of Manica flexoira (flexor manica)
only 1 in horses; SDF tendon surrounding the DDF tendon that makes a tunnel allowing it to pass through to reach the distal phalanx
identify 5 and 6
- DDF tendon
- SDF tendon
Proximal scutum is located where
with proximal sesamoid bone
fibrocartialge that lets manica flexoria to slide
purpose of middle scutum
allows gliding to final part of SDF
purpose/location of distal scutum
on navicular bone, fibrocartilage plate that allows manica flexoria to slide
last part of the tendon
Insertion point for the common digital extensor muscle
extensor process of distal phalanx
insertion of the lateral digital extensor
proximal phalanx
Name the 4 parts of the Interosseous ligament
Medius interosseous muscle is _________ in equine.
what is this important for
Tendinous; stay apparatus
In the Interosseous ligament how many branches are present
2; palmar side
In the Interosseous ligament where do the extensor branches go
dorsal; fuses with fibers of the common digital extensor tendon
what are the 3 Distal Sesamoid ligaments
most superficial to deep:
1. straight
2. oblique
3. cruciate
what are the 3 Ungular cartilage ligaments:
- Chondrocompedalis (proximal phalanx)
- Chondrocoronalis ( middle phalanx)
- Chondroungularis (distal phalanx)
where are the Distal Sesamoid ligaments atttached to
attached to the proximal sesamoid bones (base; distal part)
where is the straight distal sesamoid ligaments
most superficial at the base of sesamoid bones and goes to the middle phalanx
where are the 3 Ungular cartilage ligaments:
inside the hoof, very protected
very short and strong!
identify the digit deep ligaments
what are the purpose of these ligaments
joint the sesamoid to digits
Palmar ligament (Intersesamoidean
ligament) holds what structures
holds the 2 proximal sesamoid bones together
Collateral sesamoid ligament holds what structures
joint sesamoid bone with metacarpal bone/ sesamoid and proximal phalanx
Short sesamoid ligament holds what structures
base of sesamoid to proximal part of proximal phalanx
The more distal collateral sesamoid ligament holds what structures
“suspensory navicular ligament”
join distal sesamoid with proximal phalanx
Impair sesamoid ligament is also called the _________.
what structures does this hold
disal navicular ligament
short/strong ligament that holds navicular bone and distal phalanx
EDIT
identify 1 and 2
Carpal retinacula
1. carpal tunnel
2. flexor retinaculum
identify structures 1 and 2
purpose of retinacula
holds tendons in place!
purpose of palmar annular ligament
holds the manica flexoria (flexor manica)
Pelvic limb differences:
Proximal accessory (Check) ligament is _______, that function is supplied by the
insertion of the tendon in the_________
absent, calcanean tuber
Pelvic limb differences:
T/F Distal accessory (Check) ligament is thinner and sometimes absent
true
Pelvic limb differences:
SDF tendon attaches to the ______ and then continues distally with
similar insertion in the ____
calcanean tuber; digit
Pelvic limb differences:
DDF tendon slides over the ____________of the calcaneus
Sustentaculum tali
Identify the zones
what is this a picture of
Annular ligaments (retinacula)
what is the star
large palmar recess(*) of the Metacarpophalangeal joint [fetlock]
what is this joint
Distal interphalangeal joint (coffin joint)
what is a Scutum
groove
Distal Sesamoid ligaments are a continuation of what ligament
Interosseous ligament
what cut is the best to see the impair sesamoid ligament
sagittal cut
