Bovine Flashcards
What is the function of the bovine foot?
carry weight
transfer body weight to ground
absorb impact
Describe the main tissues in a bovine foot.
hoof - epidermis
corium - dermis, nerves & BV
bone - PIII (pedal bone) & PII
Draw & label a schematic of the key structures of a hoof.
add photo
What is the main material of the hoof structure?
keratin horn tubules
intertubular horn matrix
What are horn tubules?
strengthening structures
not in white line
density = wall>heel>sole
What are lamellae in hooves?
series of ridges inside hoof wall
interconnect with laminae of corium
attach hoof to underlying structures
Describe the hoof wall.
grows downward from coronary band - produced from coronary corium
key weight bearing surface
grows ~5mm/month
Describe the hoof sole.
grows downward from solar corium no lamellae horn tubules & intertubular matrix (keratin) concave non weight bearing ~10mm thick grows ~5mm/month
Describe the white line.
cemented junction between hoof wall & sole
bulb of heal to 1st 1/3 of axial wall
no horn tubules
weak
Describe the periople.
beneath coronary band skin/horn junction soft protects periodic corium shock absorber
Describe the heel.
rounded continuation of perioplic layer soft w/ underlying digital torus shock absorption compressed when weight bearing
Describe the palmar/plantar surface.
sole & heel
interdigital cleft separates lateral & medial claw, separates heel bulbs
In what order does the hoof contact the ground?
heel digital torus abaxial walls toe foot leaves ground
What are the components of the papillary corium?
perioplic corium
coronary corium
corium of sole
Describe the laminar corium.
laminae interconnect with lamellae of hoof wall
lateral has larger area of laminae
