The long and short pastern bones are hinged, although they only have minimal flexion. Why
Their ligamentous attachments are extremely tight. This enables the pastern to withstand tremendous force during movement
1 of 22
The phalanxes equate to which human bones?
Fingers or toes
2 of 22
Give two other names for the splint bones
Second/fourth metacarpal, Medial/lateral small metacarpal

Give two other names for the Cannon Bone
LArge Metacarpal / Third Metacarpal
4 of 22
Give three other names for the Long Pastern bone
P1, First Phalanx, Proximal Phalanx
5 of 22
Give three other names for the Short Pastern Bone
P2, Second Phalanx, Middle Phalanx
6 of 22
Give three other names for the Pedal Bone
Coffin Bone, Distal Phalanx, Third Phalanx, P3

What do the intermetacarpal joints bring together? And what kind of joints are they?
They join the splints to the knee or hock, and they are Fibrous (connected only by ligaments)
8 of 22
Give another name for the Fetlock Joint
Metacarpophalangeal
9 of 22
Give another name for the Pastern Joint
Proximal Interphalangeal Joint / PIP joint
10 of 22

Where does the Internal Arch theory originate?
Started as a theory by Bob Bowker and expanded upon by KC La Pierre
12 of 22
What are the structures which form the internal arch?
Coronet Band, DDFT, Digital Cushion, Frog Corium, Lateral Cartilages, Pedal Bone, Navicular Bone
13 of 22
Generally speaking, the stronger the internal arch, the greater the what?
Shock absorbing capabilities of the hoof
14 of 22
Aside from shock absorbing, name another function of the internal arch as a whole
Acts like a spring storing and releasing energy as it deforms under load and springs back into shape when the load is relieved
15 of 22
Tendons are relatively inelastic. What is their purpose?
They enable flexion and extension of the joints to allow the skeleton to move
16 of 22
What are the ends of tendons attached to?
Muscle at one end and bone at the other
17 of 22
Which of the two flexor tendons in the distal limb is most axial
DDFT
18 of 22
Which is the only tendon which can create flexion in the coffin joint?
DDFT
19 of 22
How is the DDFT attached to the LAteral Catilages?
Ligaments
20 of 22
The Superficial Digital Flexor Tendon extends how far down the limb?
The pastern bones. It splits at the level of the long pastern bone and attached to the proximal part of the short pastern bone.
21 of 22
What is the distal end of the Superficial Digital Extensor Tendon attached to?
It splits at the distal end and attaches to the short pastern bone
