Equine Pelvic Limb Nerves Flashcards
The superficial peroneal n. innervates __________.
The superficial peroneal n. innervates cutaneous to lateral aspect of crus to fetlock; lateral digital extensor m.
Which nerve can be palpated here?
(this is the back end of a horse by the way… come on)
tibial nerve
Damage to the __________ nerve results in “knuckling over”
common peroneal n.
The deep peroneal n. innervates __________.
The deep peroneal n. innervates cutaneous distribution to pes.
The **lateral dorsal metatarsal n. **innervates __________.
The lateral dorsal metatarsal n. innervates cutaneous distribution to dorsal metatarsus.
Which nerve can be found running alongside the great metatarsal a.?
lateral dorsal metatarsal n.
The lateral dorsal digital n. innervates __________.
The lateral dorsal digital n. provides cutaneous innervation to the dorsal digit.
The **caudal cutaneous sural n. **innervates __________.
The caudal cutaneous sural n. innervates cutaneous distribution to caudal crus.
The **medial plantar n. **innervates __________.
The medial plantar n. provides cutaneous innervation to medioplantar metatarsal.
The **medial (plantar) digital n. **innervates __________.
The medial (plantar) digital n. provides cutaneous innervation to medial digit.
The **dorsal branches of the digital nn. **innervate __________.
The dorsal branches of the digital nn. provide cutaneous innervation to the dorsal digit.
The communicating branch from the tibial nerve connects which two nerves?
medial and lateral plantar nerves
The **lateral plantar n. **innervates __________.
The **lateral plantar n. **innervates interosseus m & cutaneous distribution to lateroplantar metatarsus.
The **lateral (plantar) digital n. **innervates __________.
The lateral (plantar) digital n. provides cutaneous distribution to the lateral digit
Which branch of the tibial nerve is responsible for innervation to the interosseus m?
lateral plantar n.
Which branch of the tibial nerve is responsible for cutaneous innervation to the caudal crus?
caudal cutaneous sural n.
Which branch of the tibial nerve is responsible for cutaneous innervation to the medioplantar metatarsal?
medial plantar n.
Which branch of the sciatic nerve is responsible for cutaneous innervation to the lateral leg?
common peroneal n.
A **palmar digital nerve block **is at the level of the ________ joint or below
A palmar digital nerve block is at the level of the pastern joint or below.
It blocks the palmar/plantar & distal parts of the hoof, PIII, termination of the DDF, and most of the coffin joint
Are peroneal & tibial nerve blocks proximal or distal to the hock?
proximal to the hock
**common peroneal n. **and tibial n. are both branches of the ________ nerve
sciatic n.
If an animal suffers obturator nerve paralysis, what action becomes impossible?
adduction of the limb
If an animal comes into your clinic and it is unable to flex the hock or extend the digits (animal is knuckling over), which nerve is most likely to be affected?
peroneal nerve
pronounced flexion of the hock & overextension of the digits is indicative of ____________ nerve paralysis
tibial
Which nerve provides sensation to the perianal area?
pudendal n.
