the humerus has a twisted appearance due to a spiralling groove that carries the brachial muscle and radial nerve. what is the lateral tuberosity of this spiral, and what is the medial tuberosity?
lateral is deltoid tuberosity and medial is trees tuberosity
39
on the humerus there are 2 tubercles on top (greater and lesser) and an articular condyle (or trochlea in LA) on bottom, while on the humerus there are ______ and _______
trochanters (greater, lesser, and in horses third) and two condyles (medial and lateral)
40

plane, hinge, pivot, condyloid, ellipsoidal, saddle, ball and socket
44

In extended position, the patella locks against the trochlea and medial patellar ligament and parapatellar ligament “hook” over medial trochlear ridge
45
the 3 equine fetlock sesamoidean ligaments are
collateral, straight, and oblique. they provide tension for weight to be distributed and prevent hyperextension and collapse
46
