During elbow flexion, the vertical anterior part of the trochlea keeps the upper arm and forearm aligned ( when viewed in front ).
12.
The groove running across the trochlea is, in most people, vertical on the anterior side but spirals off on the posterior side.
13.
This is quite unlikely however; it certainly lacks the backwards-projecting growth of the trochlea where the middle toe attaches that is typical for Avisauridae.
14.
The accurate adaptation of the trochlea of the humerus, with its prominences and depressions, to the trochlear notch of the ulna, prevents any lateral movement.
15.
Behind the trochlea is a posterior process with a medial and a lateral tubercle separated by a groove for the tendon of the " tarsale proximale intermedium ".
16.
Above the back part of the trochlea is a deep triangular depression, the olecranon fossa, in which the summit of the olecranon is received in extension of the forearm.

""'Oxymeris trochlea " "'is a species of sea snail, a marine gastropod mollusk in the family Terebridae, the auger snails.
18.
Although not generally termed condyles, the trochlea and capitulum of the humerus act as condyles in the elbow, and the femur head acts as a condyle in the hip joint.
19.
One form of patellofemoral syndrome involves a tissue-related problem that creates pressure and irritation in the knee between the patella and the trochlea ( patellar compression syndrome ), which causes pain.
20.
Further differences between " Odontopteryx " and " Pelagornis " are found in the tarsometatarsus : in the present genus, it lacks a deep trochlea is conspicuously expanded forward.
