| fibrae intercrurales | Horizontal arched fibres that pass from the inguinal ligament across the medial and lateral crura of the superficial inguinal ring. Synonym: fibrae intercrurales, intercolumnar fasciae, intercolumnar fibres. (05 Mar 2000) |
| fibrae lentis | <biology, ophthalmology, physiology> The elongated cells of ectodermal origin forming the substance of the crystalline lens of the eye. Synonym: fibrae lentis. (05 Mar 2000) |
