| These points are located between the crura and the other connected structures. |
| Between the two crura of the fornix is a white, triangular lamina, known as the fornical commissure. |
| The brachial valve contains short crura and a prominent, branched cardinal process. |
| They are continuous with a similar layer of fibres on the floor of the mid-brain, where they constitute the crura cerebri. |
| The lower lateral cartilages become shortened at the medial crura and elongated and displaced in the lateral crura. |
| Through the crura pass the splanchnic nerves, and in addition to these the left crus is pierced by the vena azygos minor. |
