Distal limb Flashcards
Label the joints
What is the light orange tendon
Common digital extensor:
Main extensor of digits
Receives branches from suspensory ligament (interosseus) (green)
What is the dark orange tendon
Lateral digital extensor:
Lateral to common digital extensor
What is the bright red tendon
Long digital extensor:
Main digital extensor of hindlimb
Receives slip from interosseus ligament (blue)
What is the dark red tendon
Lateral digital extensor
What are the flexor tendons of digits
Located on palmar aspect
Superficial digital flexor tendon:
Subcutaneous & palpable
Forms sleeve around DDFT at level of proximal sesamoids (manica flexoria)
Flexes proximal & middle phalangeal joints & stabilises fetlock joint
Deep digital flexor tendon:
Runs deep to SDFT
Passes through manica flexoria
Label the tendons
Fill in the table for distal forelimb
Describe innervation of distal hindlimb
Tibial – muscular supply to extensors of hock & flexors of digits
Fibular – muscular supply to flexors of hock & extensors of digits
What nerve block is this
Palmar digital nerve block:
Palmar digital nerves in pastern region
Desensitises hoof structures other than dorsal coronary band
What nerve block is this
Abaxial sesamoid nerve block:
Palmar digital nerves on abaxial surface of proximal sesamoid bones
Desensitises digit & caudal fetlock joint

What are the parts of a ruminant claw
Dermis:
Living tissue
Blood vessels
Nerves
Role: supply
Epidermis:
Inner part = living cells that produce horn
Outer part = dead horn
Role: horn formation
