Hoof/Claw Flashcards
Hoof capsule
epidermal part of the hoof
Parts of the Hoof
epidermis and dermis
Foot
hoof capsule + everything inside it (CCT, bn, etc.)
Corium
dermis
keratinized surfaces of hoof
wall, sole, frog
hardness of keratin (Hardest to softest)
wall > sole > frog
Divisions of hoof wall
Stratum externum
Stratum medium
Stratum internum
Stratum Externum
- outermost layer of hoof wall
- very thin! thickest proximally
- made of horn tubules & intertubular horn
Stratum Medium
- middle layer of hoof wall
- VERY thick.
- made of horn tubules and intertubular horn
- very dense & tough.
- were shoe nails go
Stratum Internum
- innermost layer of hoof wall
- lots of projections/laminae that run from proximal to distal (PRIMARY LAMINAE)
- ridge inside hoof wall, seen grossly, non-pigmented
Hoof capsule made by…
stratum basale!
5 epidermal regions of the hoof
- Stratum Externum
- Stratum Medium
- Stratum Internum
- Sole
- Frog
What supports the epidermal regions of the hoof?
dermis or corium
5 dermal regions of hoof
- Perioplic Dermis
- Coronary Dermis
- Laminar Dermis
- Sole Dermis
- Frog Dermis
Perioplic Dermis supports
stratum externum
Coronary dermis supports
stratum medium
laminar dermis supports
stratum internum
sole dermis supports
sole
frog dermis supports
frog
Perioplic dermis
- narrow layer of dermis
- supports stratum basale
- small dermal papillae present
Dermal papille
run from dermal region into the epidermal region to supply it with nutrients
Coronet
junction of skin of distal leg with proximal boundary of the hoof wall.
