Q

Coronary band

A

Is found where the hoof capsule meets the hairline of the leg. It contains the periople, and the coronary corium, and is the main growth and nourishment area of the hoof wall.

Q

Deep digital flexor tendon

A

Flexor tendon that runs down back of cannon bone. At the lower end it widens to connect to the lower end of the 3rd phalanx at the back, in an aponeurosis.

Holes in the pedal bone

24
Q

Ground surface

A

The part of the hoof capsule that is in contact with the ground.

25
Heel area
The back third of hoof capsule when viewed from the side
26
Hoof capsule
The horny wall encapsulating the lower digit and the internal structures contained within it.
27
Hoof wall
The outer capsule of the hoof made of modified keratinised epithelial cells
28
Hyaline cartilage
Pliable cartilage that forms the lateral cartilage of the hoof capsule.
29
Interosseus ligament
Ligament that tie bones together
30
Keratin
Main protein component of horn growth it hardens and cements epithelial cells
31
Laminae
Corium of the 3rd phalanx (sensitive laminae). The main laminae that grow out in thin plates are known as primary laminae, and from each of these 100-150 secondary laminae grow out at right angles
32
Lateral cartilage
Two wings of cartilage that grow out of the back of the 3rd phalanx and extend above the hoof capsule at heel.
33
Lateral Palmer nerve
Nerve supplying the hoof capsule. It runs down the outside of the digit, and supplies the pedal, navicular, and part of lateral cartilage, laminae, frog and sole coriums
34
Long Pasternak bone
Aka 1st phalanx
35
Methionine
Essential amino acid needed for production of merit in in the hoof wall
36
Quarter
The middle third of the hoof capsule when viewed from the side
37
Medial Palmer nerve
Morris the lateral Palmer nerve on the inside of the fetlock joint. It’s branches supply the coronary corium, part of the lateral cartilage, part of the laminar, frog and sole coriums
38
Navicular
Aka distal sesamoid bone. Small bone found at the back of the pedal joint between the 2nd and 3rd phalanx.
39
Navicular bursa
Fluid filled sac surrounding and protecting the navicular bone.
40
Oissein
Collagen type substance, one of the main components of bone
41
Pedal bone
Aka 3rd phalanx
42
Periople
Found at the top of coronary band where the hoof capsule joins the hair of the leg. Contains the perioplic corium.
43
Short Pasternak bone
Aka 2nd phalanx
44
Sole
Insensitive sole: Found on the ground surface of the hoof capsule. Consists of horny sole, and lies between the white line and the frog. Sensitive sole: lies underneath the insensitive sole, and contains the sole corium which has the nerve and blood supply to provide growth and nourishment for the sole.
45
Stratum tectorium
Acts like a water proof varnish
46
Superficial digital flexor tendon
The flexor tendon running down the outside of the deep digital flexor tendon, it splits below the annular ligament, one branch attaches to 1st phalanx and the other to the 2nd Phalanx.
47
Suspensory navicular ligament
Attached 2nd phalanx to navicular bone
48
Terminal arch
End of the digital artery at front of 3rd phalanx. From here it supplies the lower laminae and sole corium
49
Toe
The front of the hoof at the ground surface. The first third of the hoof capsule when viewed from the side.
50
Venous plexus
Vein network. Three in hoof capsule; laminar, solar, and coronary
51
White line
The join between sensitive and insensitive laminae. Seen on the ground surface between the hoof wall and sole.
