1

Coronet

Proximal edge of hoof
seen as a raised line under the distal edge of hair skin
point go growth

2

Hoof Wall

Made of Keratin
complex design
tubular and inter tubular components
controls crack growth and increases fracture thoughness

3

3 layers of Hoof wall

Stratum externum
Stratum medium
Stratum internum

4

Sole

Concave, insensitive side of foot
protects sensitive sole inside
may be bruised or punctured

5

White lines

continuation of stratum internum to bottom of hoof, where hoof wall and sole meet

6

Bars

Inwards folds of wall, originating from the apex of the frog

7

Frog

Thick triangular shaped, cornified tissue at the centre of the underside of the foot, Digital cushion lies under the frog

8

Digital Cushion and heel Bulbs

The heel bulbs are continuation of the digital cushion
Shock absorber
Support Bone structure

9

Pump Action

Weight applied, frog and digital cushion are compressed
Pressure is absorbed by slight outwards movement of bars
Helps blood flow by forcing blood out and up the veins of the horses legs

10

Lamine

Connection between inner surface of the hoof wall and outer surface of distal coffin bone

11

Lateral Cartliage

Wings on either side of coffin bone
contributes to elasticity
Absorbs shock but evening out

12

Navicular bone

Small bone sits between coffin bone and short pastern
surface at the back of the bone is smooth whichh helps in movement of the tendon over it
