horse foot

Question 1

Distal phalanx provides a solear canal for the terminal arch of

Answer 1

medial and lateral digital arteries

Question 2

branches of the terminal arch exit the parietal cortex via

Answer 2

foramens

Question 3

the parietal surface has ridges for the

Answer 3

suspensory apparatus of distal phalanx (SADP) attachment

ridges are true periosteum

Question 4

superficial digital flexor

Answer 4

branches into 2
-insert on distal extremity of proximal phalanx and proximal extremity of middle phalanx palmar to the collateral ligaments of proximal interphalangeal joint

Question 5

deep digital flexor

Answer 5

-descends between the 2 branches of superficial digital flexor
-insert on semilunar flexor surface of distal phalanx beneath the navicular impar ligament

Question 6

*common digital extensor

Answer 6

-inserts partially on proximal and middle phalanges and finally on broad extensive process of distal phalanx

Question 7

lateral digital extensor

Answer 7

inserts on lateral proximal phalanx

Question 8

dorsal extensor branch of suspensory ligament merge dorsally into

Answer 8

extensor tendons.

Question 9

the hoof wall can be divided into 3 sections,

Answer 9

the stratum externum, the stratum medium and stratum Internum

Question 10

the stratum lamellatum refers to both

Answer 10

dermal and epidermal lamellae

Question 11

the coronary band angle (line from proximal border of toe to the heel) is

Answer 11

20 degrees

Question 12

Suspensory apparatus of the distal phalanx (SADP) suspends distal phalanx to the

Answer 12

expanded inner surface of the hoof capsule

Question 13

SADP origin

Answer 13

dense reticular network of collagen bundles (stratum reticulare) embedded in the parietal cortex of the distal phalanx

Question 14

the bundles cross the sublamellar dermis are

Answer 14

at angles aligned with strain

Question 15

SADP inserts as fine collagenous filaments into the

Answer 15

lamellar basement membrane

Question 16

SADP function

Answer 16

acts to enable hoof wall to bear weight by redirecting forces from distal phalanx to hoof wall

Question 17

Laminitis dysfunction of

Answer 17

suspensory apparatus of distal phalanx

Question 18

the production of tubular horn of the periople, hoof wall and bars, white line, sole and frog is

Answer 18

constant as foal grows

Question 19

mitosis is equally frequent in lamellar sections but only in

Answer 19

short proximal zone, on the inner shoulders of the coronary groove

Question 20

in the adult horse, mitosis in the form of mitotic figures is observed in

Answer 20

section of tubular horn tissue
