| raphe pharyngis | The central line of the pharynx posteriorly where the muscular fibres meet and partly interlace. Synonym: raphe pharyngis. (05 Mar 2000) |
|---|---|
| raphe pontis | The continuation of the raphe medullae oblongatae into the pars dorsalis (or tegmentum) pontis. (05 Mar 2000) |
| raphe pterygomandibularis | A tendinous thickening of the buccopharyngeal fascia, separating and giving origin to the buccinator muscle anteriorly and the superior constrictor of the pharynx posteriorly. Synonym: raphe pterygomandibularis, pterygomandibular ligament. (05 Mar 2000) |
| raphe retinae | The horizontal line separating the superior and inferior portions of the temporal retina over which the retinal nerve fibres do not course. (05 Mar 2000) |
| raphe scroti | A central line, like a cord, running over the scrotum from the anus to the root of the penis; it marks the position of the septum scroti. Synonym: raphe scroti, Vesling's line. (05 Mar 2000) |
| median longitudinal raphe of tongue | <anatomy> Median groove or median longitudinal raphe of tongue; raphe linguae; a slight longitudinal depression running forward on the dorsal surface of the tongue from the foramen caecum. Synonym: sulcus medianus linguae, median longitudinal raphe of tongue, raphe linguae. (05 Mar 2000) |
| median raphe cyst of the penis | A cyst of the raphe penis resulting from incomplete closure of the urethral groove, becoming clinically evident in childhood or later. (05 Mar 2000) |
| penile raphe | The continuation of the raphe of the scrotum onto the underside of the penis. Synonym: raphe penis. (05 Mar 2000) |
| perineal raphe | The central anteroposterior line of the perineum, most marked in the male, being continuous with the raphe of the scrotum. Synonym: raphe perinei. (05 Mar 2000) |
| pharyngeal raphe | The central line of the pharynx posteriorly where the muscular fibres meet and partly interlace. Synonym: raphe pharyngis. (05 Mar 2000) |
| scrotal raphe | A central line, like a cord, running over the scrotum from the anus to the root of the penis; it marks the position of the septum scroti. Synonym: raphe scroti, Vesling's line. (05 Mar 2000) |
| pterygomandibular raphe | A tendinous thickening of the buccopharyngeal fascia, separating and giving origin to the buccinator muscle anteriorly and the superior constrictor of the pharynx posteriorly. Synonym: raphe pterygomandibularis, pterygomandibular ligament. (05 Mar 2000) |
| Stilling's raphe | The transverse interdigitations of fibre bundles across the anterior median fissure of the medulla oblongata at the decussation of the pyramidal tracts. (05 Mar 2000) |
| lateral palpebral raphe | A narrow fibrous band in the lateral part of the orbicularis oculi muscle formed by the interlacing of fibres passing through the upper and lower eyelids. Synonym: raphe palpebralis lateralis, palpebral raphe. (05 Mar 2000) |
| abducens nucleus | Nucleus of abducent nervenucleus abducentis, a group of motor neurons in the lower part of the pons, innervating the lateral rectus muscle of the eye; unique among motor cranial nerve nuclei in that it consists of two distinct populations of neurons: neurons that give rise to fibres forming the abducens nerve root and those internuclear neurons whose processes cross the midline, ascend in the opposite medial longitudinal fasciculus, and terminate upon specific oculomotor neurons; considered a primary centre for mechanisms controlling conjugate horizontal gaze. Synonym: nucleus nervi abducentis. (05 Mar 2000) |
