Section 1

Question Answer
bracial plexus nervessuprascapular, axillary, median, ulnar, radial, musculocutaneous
suprascapular innervatesinfraspinatus & supraspinatus
infraspinatus & supraspinatus functionshoulder extension & brace
Problem with suprascauplar never causesshoulder slip
musculocutaneous nerve innervatesbiceps brachii & feeling on medial forearm
biceps brachii functionflexion of the elbow
axillary nerve innervatesdeltoids, teres minor/major & craniolateral skin
deltoids, teres minor/major functionflexion of shoulder joint
radial nerve innvervateslateral cutaneous antebrachial nerve, triceps and lower leg
larget brachail plexus nervemedian
median nerve innervatesmedial & lateral palmer nerves
ulner never innervatesDDF muscle, ulnar carpal flexor and digit flexors
sensation from ulnar nervecaudal cutaneous antebrachial nerve & palmer/dorsal branches
distal nervesmedial & lateral palmer, palmer & dorsal ulnar
medial cutaneous antebrachial nerve innervated bymusculocutaneous
lateral cutaneous antebrachial nerve innervated byradial
craniel cutaneous antebrachial nerve innervated byaxillary
caudel cutaneous antebrachial nerve innervated byulnar
brachial plexus lies where?behind scapula

Section 2

Question Answer
lumbosacral plexus nervesfemoral, gluetal (craniel & caudel), sciatic and obturator
femoral nerve innervatesquads
quadricep functionabduction
craniel gluteal innervatestensor fascia latae, deep & middle glut
tensor fascia latae, deep & middle glut functionflexion/extension of hip
caudel gluteal innervatessuperficial gluteal muscle
superficial gluteal muscle functionextensor of hip
femoral branch nervesephanous
sephanous nerve functionmedial limb sensation & seterius muscle
seterius muscle functionflexion, adduction & rotation of hip
obturator nerve innervatesgracelius, adduction, internal/external obturator
highest risk to obturaterbrocken pelvis - often seen when foaling
highest risk to sciatic nerve hip fractures
sciatic nerve innervateshamstrings
branches of sciatic nervelateral sural, superficial & deep peroneal nerve
lateral sural, superficial & deep peroneal nerve functionsensation of skin
tibia nerve sensationplanter aspect of foot
tibia nerve innervationgatroc, soleus & digital muscles
gatroc, soleus & digital muscles functionextension of hock and flexion of digits (gastroc extends stifle)
hing foot innervationtibia & peroneal nerves

Section 3

Question Answer
EHV-1 & EHV-4 are what type of diseaserespiratory
EHV-1 & EHV-4 affect on pregnancy1 = abort 4 = no difference
EHV-1 clinical signs apart from abortionneuropathy (nerve pain)
EHV-1 & EHV-4 symptomsataxia, paralysis, weakness & spastic bladder
treatment supportive therapy
best way to preventvaccinaton
foal bacteria infectionse.coli & salmonella
horse bacteria infectionsstreptococcus equi (strangles)
neoplasianew growth
neoplasia can occurlymph nodes, blood, skin, glial cells (affect brain & spinal corad)
length of onsetsudden
what gradually occursparesis
sporadic stringhalt is a .... diseaseneuromuscular
sporadic stringhalt charecterisationdramatic flexion of the hind limb (usually one sometimes both)
does sporadic stringhalt cause neurogenic changesno
sporadic stringhalt often proceedestrauma
other type of stringhaltplant associated - not permenant
shivers characterizationtrembling of back/limbs when picking up/backing up. however gait normal
shivers severitygets worse over time
equine motor neuron disease causes degeneration of lower motor neurons
equine motor neuron is closely linked with low vit E
success of equine motor neuron treatment50/50
trauma causes damage to what peripheral nervous system
PNS damage causes what type of atrophyneurogenic atrophy
complete paralysis from PNS truma occurs how long after?around 12 months if no innervation is shown
lower motor neuron functioninnervating structures within periphery
facial nerve damage signsdrooping eyelid, ears and muzzle
suprascapular nerve damage signssweeny of shoulder
radial nerve damage affectsability to bear weight & extension
medial and nerve damage causes goose stepping - hyperextension of carpus down
femoral nerve damage causesaffects quads - cannot bear weight or extend
obturator nerve damage causesaffects adductor - wide stride
sciatic nerve damage causesoverextension of hock/stifle
tibial nerve damage causesoverflexion & exaggerated placement of limb
tibial nerve damage shows asstringhalt
polyneuris equidenegenration of nerves
