Answer 1

Question 2

Answer 2

• palmar/plantar

• interdigital in cattle

Question 3

what is the function of the dorsal elastic ligaments in cats

Answer 3

to lift the claws off the ground (retraction)

can make the digits look odd in rad

Answer 4

radial nerve

Question 5

Question 9

what are the locations of 2 equine distal nerve blocks

Answer 9

• palmar digital nerve block
• abaxial sesamoid nerve block (sesamoids of fetlock)

Question 10

what nerves does the palmar digital nerve block affect, what strutures do you palpate to find the site and what strucutres are anesthetised

Answer 10

• palmar digital nerves in pastern region
• neurovascular bundles abaxial to flexor tendons (nerve is most cranial: VAN)
• desensitised hoof structures other than the dorsal coronary band

Question 11

what nerves does the abaxial sesamoid nerve block affect, what structures do you palpate to find the site and what structures are anesthetised

Answer 11

• palmar digital nerves on abaxial surface of proximal sesamoid bones
• neurovascular bundles palpable over sesamoids (VAN)
• desensitizes the digit and caudal fetlock joint
