| heart rupture | Laceration or tearing of the walls of the heart, of the interatrial or interventricular septum, of the papillary muscles or chordae tendineae, or of any of the valves of the heart. Rupture may be due to a variety of pathological entities, however, the majority are secondary to myocardial infarction (heart rupture, post-infarction). (12 Dec 1998) |

| splenic rupture | A term usually used to describe the result of blunt injury to the spleen. In this case, there will be laceration and haemorrhage from the spleen. This type of injury is most often seen in motor vehicle accidents. A rare form of spontaneous splenic rupture has been known to occur with mononucleosis and other disease processes which cause splenic enlargement (leukaemia). (27 Sep 1997) |
| oesophageal rupture | Named after Captain Boerhaave, a Dutch ship captain, who was the first patient this condition was described in. Traumatic rupture of the lower oesophagus can occur with significant blunt chest trauma, during CPR or in some conditions of forceful protracted vomiting. This condition is much more common in the patient with a pre-existing oesophageal disease such as reflux oesophagitis. The chest X-ray will typically show an abnormal left cardiac border with free fluid within the left hemithorax (pleural effusion). Patients will experience immediate chest pain, which may radiate to the neck, accompanied by shock, sepsis and death within 48 hours if untreated. (27 Sep 1997) |

| ganglionic layer of optic nerve | <anatomy, nerve> The inner layer of multipolar neurons in the retina consisting of the relatively large neurons that give rise to the fibres of the optic nerve. Synonym: stratum ganglionare nervi optici. (05 Mar 2000) |
| vascular circle of optic nerve | <anatomy, nerve> A network of branches of the short ciliary arteries on the sclera around the point of entrance of the optic nerve. Synonym: circulus vasculosus nervi optici, circulus arteriosus halleri, circulus zinnii, Haller's circle, Zinn's corona, Zinn's vascular circle. (05 Mar 2000) |
| coloboma of optic nerve | <anatomy, nerve> A congenital notch in the formation of the optic nerve, appearing as a craterlike excavation at the optic disk. (05 Mar 2000) |
| postlaminar part of optic nerve | <anatomy, nerve> The portion of the optic nerve posterior to the lamina cribrosa of the sclera. Synonym: pars postlaminaris nervi optici. (05 Mar 2000) |
| prelaminar part of optic nerve | <anatomy, nerve> The portion of the optic nerve anterior to the lamina cribrosa of the sclera. Synonym: pars prelaminaris nervi optici. (05 Mar 2000) |
