| The trochlear nerve nuclei are located ventral to the mesencephalic aqueduct. |
| In the anterior view, the trochlear notch of the ulna is not seen through the humerus. |
| Flexible trochlear route over the entire patellar course assures good patellar stability. |
| Each trochlear nerve makes its exit through the caudal tectum, immediately lateral to the frenulum of the superior medullary velum. |
| The coronoid process is the anterior protrusion which forms part of the border for the trochlear notch. |
| The exceptions are the superior oblique, which is enervated by the trochlear nerve, and the lateral rectus, which is enervated by the abducens. |
