DISTAL LIMB Flashcards
Where are the flexor muscles located
Palmar aspect of limb
Where are the extensor muscles located
Dorsal-lateral aspect of the limb
Which muscles cause extension of the digits in the forelimb
Common digital extensor
Lateral digital extensor
Which nerve innervates the forelimb extensors
Radial nerve
Which is the main extensor of digits in the forelimb
Common digital extensor
Where does the common digital extensor insert
On extensor process of P3
Where is the lateral digital extensor located
Located lateral to the common digital extensor on the forelimb
Which nerve innervates the extensor muscles of the hindlimb
Fibular nerve
Where do the extensor muscles of the digit originate
From the lateral epicondyle of femur
Which muscles are responsible for extension of the digits in the hindlimb
Long digital extensor
Lateral digital extensor
Where does the lateral digital extensor inset in a horse
On P1
Where does the long digital extensor insert
Inserts on extensor process of P3
Where does the lateral digital extensor insert in hindlimb of horse
Fused with the long digital extensor
What is responsible for flexion of the digits
Superficial digital flexor tendon
Deep digital flexor tendon
Where do the flexors of the digit arise in the forelimb
Muscles rise from the medial epicondyle of humerus
Where do the flexors of the hindlimb arise
From the caudal aspect of femur, tibia ad fibular
Which nerve innervates the flexors of the forelimb
Ulna and medial nerves
Which nerve innervates the flexors of the hindlimb
Tibial nerve
Where does the SDFT split
At the distal end of P1
Where does the SDFT insert
On P2
What is the manica flexoria
Where SDFT forms sleeve around DDFT a proximal sesamoids
Where is the DDFT
Runs deep to SDFT and passes through manica flexoria
Where does the DDT insert
On flexor tuberosity of P3 of each functional digit
What are bursae
Tough connective tissue sacs that contain synovial fluid
