the brachiocephalicus m. and omotranservarius do what
fuse together
do equine have a pronator or supinator muscles?
no
supracondylar foramen
medial distal part of humerus, found in feline no opening of supratrochlear foramen gives passage to median nerve/brachial artery
true or false in all species do the msucle that span the glenohumeral joint make up support for this joint
true
what is fistulous withers?
chronic inflammatory disease by pus filled wounds/swelling on horse's withers, misfited saddles, yokes injection, bacteria infection Brucella sp, usually at surpraspinous bursa between nuchal ligament and first throacic dorsal spinous processes
In fistulous withers why is the fascia sheath of the rhomboideus important?
helps in ventral drainage of any suppurative process in area of withers
what does the dorsoscapular ligament have to do with fistulous withers?
necrossi and inflammation is not spread laterally but instead drains ventrally and not noticed til the animal is lame or has a pocket of infection in the ventral aspect of the sternum near medial aspect of thoracic limb
what is sweeney?
laxity in shoulder joint due to aucte/chronic repetitive injury near pt of shoulder
How does sweeny occur in equine?
