Anatomy Flashcards
Does the proximal ulnar growth plate contribute to ulnar length?
No- olecranon Some breeds ( GSD, greyhounds) have separate ossification center at anconeal process
What nerves do you avoid with arthroscopy of the elbow?
Medial portals
median nerve more cranial
ulnar nerve more caudal
What nerves/ structures do you avoid with arthroscopy of the carpus?
superficial radial nerve w/ cranial superficial antebrachial artery and cephalic vein
CDE and lateral digital extensor
Name the carpal bones (7)?
intermedioradialcarpal
ulnar
accessory
CI-IV
what bones does the palmar fibrocartilage incorporate?
Attached to all the proximal carpal bones, C1-C4, and the proximal palmar aspect of the base of metacarpals III-V
NOT the accessory carpal bone
Where is the most common location for carpal hyperextension injury
Carpometacarpal joint most common location for hyperextension injury
Where does the carpal flexor retinaculum extend?
FR: Extends from medial aspect of the accessory carpal bone to the radial styloid process and distally to the intermedioradial and C1
What is ectrodactyly?
split in metacarpal bone , a cleft between metacarpal bones
name the bones of the tarsus (7)
talus
calcaneus
central tarsal
TI-IV
Name arteries that supply the pes (2)? veins?
cranial tibial artery –> dorsal pedal
plantar branch of the saphenous artery
(medial and lateral saphenous veins)
what are the cutaneous sensory innervations of the pes?
Femoral –> saphenous = dorsomedial skin
Tibial –> plantar surface and lateral digit V
peroneal –> dorsal
what are the cutaneous innervations to the manus?
radial –> dorsomedial
Ulnar –> caudal+ digit 5 lateral aspect
(musculocutaneous –> proximal/medial brachium)
What % or tarsal ROM is at the calcanealcrural joint?
90%
Name articulations of the tarsus (6)
Row 1: tarsocrural
Row 2: talocalcaneal, talocalcaneocentral
centrodistal
Row 3: calcaneoquartal, tarsometatarsal
What is the most substantial supporting ligament of the tarsus? when is it taught, when is it loose? ( in dogs)
Short part of medial collateral (tibiotalar)
loose in extension, tight in flexion
Which lateral collateral ligament is tight in flexion in the tarsus in dogs?
talofibular = primary support in flexion
What ligaments are tight in extension, loose in flexion in the dog?
superficial medial collateral
tibiocentral short medial collateral
long lateral collateral, short calcaneofibular
what’s different about the cat’s tarsal ligaments?
no long ligaments
medial = oblique tibiotalar* and straight talocentral
lateral = calcaneofibular and talofibular*
Racing greyhounds are susceptible to what kind of fractures?
Type IV central tarsal bone fractures (right) medial slab with dorsal slab
accessory carpal bone (right side in80%)
what muscles compose the achilles tendon?
Go grab big fat strawberries (stat:D)
Gastrocnemius gracilis biceps femoris semitendinosus (SDF)
What are rotator muscles of the hip?
OGQ
PMD
External/Lateral rotation = internal and external obturator, gemelli, quadratus femoris
(sciatic and obturator inervation)
Internal = Medial rotation = middle and deep gluteal, piriformis
(cranial gluteal innervation)
Name the stabilizers of the shoulder joint (muscles) 5
Medially = subscapularis, coracobrachialis (subscapular + musculocutaneous n.) laterally = infraspinatus, teres minor (suprascapular+ axillary n) cranially = supraspinatus suprascapular
Medial shoulder rotation (2)
subscapularis and teres major
