Muscles Of Antebrachium And Manus Flashcards
Anatomy of tendon sheath
Mesotendon - attaches tendon to underlying bone
Synovial cavity - surrounds tendon
Synovial covering of tendon
Synovial living of cavity
Synovial sheath
Functional groupings : extensors
Extensors of carpus & digits : craniolateral
Origin :Lateral (extensor) epicondyle of humerus
Attach on lateral side
Functional groups : flexors
Flexors of carpus & digits : caudomedial
Origin : medial (flexor) epicondyle of humerus
Flexor manica
Superficial digital flexor tendon divides to allow deep digital flexor tendon to pass, attaches p2 to p3
Extremely large in horses
Functional groups : supinator/pronator
Supinator
Pronator teres
Pronator quadratus (bridges radius /ulna)
Muscles of manus in cat vs dog
Brachioradialis - well developed vs dog
Muscle bellies tend to be longer/farther down tendon
Muscles of manus more developed, finer use of claws vs dogs
Specialized distal phalanges
Medial dorsal elastic ligament
Maintains hyper extension of p3 in cats (tucked)
Largest retractor ligament
Claws out = flexion
