Limb Nerves Flashcards
What plexus supplies the pelvic limb?
Lumbosacral plexus
What plexus supplies the forelimb?
Brachial plexus
Describe clinical signs of sub scapular nerve damage.
- Supraspinstus may atrophy
- Gait remains normal
Describe clinical signs of musculocutaneous nerve damage.
- Little affect on gait as compensatory adaption (from pronator teres) can occur with damage to elbow flexors
Describe the clinical signs of radial nerve damage.
- Knuckling of paw as flexor muscles are unopposed
Describe the clinical signs of obturator nerve damage.
- Loss of adduction function, resulting in splayed femoral limbs
Describe the clinical signs of femoral nerve damage.
- Quadriceps femoris paralysis
- Lack of stifle extension
- Affected limb is not able to bear weight
Describe the clinical signs of damage to the sciatic nerve.
- Stifle flexors paralyzed
- Results in unopposed extension of stifle
What is Sweeny?
- Damage to the sub scapular nerve
- Allows animal to stand but shows outward slip of shoulder joint during propulsion
- Muscle wastage occurs and causes scapula to appear prominently
Describe the clinical signs of damage to the auxiliary nerve.
- No clinical signs due to compensatory action of other muscles
What is the sourcing branch of the tibial nerve and describe the clinical signs of tibial nerve damage.
- Sciatic nerve
- Unopposed extension and flexion of the limb
