- raphe
- The line of union of two contiguous, bilaterally symmetrical structures. SYN: rhaphe. [G. rhaphe, suture, seam]- amnionic r. the line of fusion of the amnionic folds over the embryo in reptiles, birds, and certain mammals.- r. anococcygea SYN: anococcygeal ligament.- anogenital r. in the male embryo the line of closure of the genital folds and swellings extending from the anus to the glans of the penis; it is differentiated in the adult into three regions: perineal r., scrotal r., and penile r..- r. corporis callosi a slight anteroposterior furrow on the median line of the upper surface of the corpus callosum.- iliococcygeal r. [TA] portion of anococcygeal body formed by the attachment of the right and left halves of the iliococcygeus (muscle) to each other in the midline, posterior to the anal canal. SYN: r. musculi iliococcygeus [TA].- lateral palpebral r. a narrow fibrous band in the lateral part of the orbicularis oculi muscle formed by the interlacing of fibers passing through the upper and lower eyelids. SYN: palpebral r., r. palpebralis lateralis.- r. medullae oblongatae [TA] the seamlike median zone of the medulla oblongata, marked by intercrossing fiber bundles among which lie scattered neuronal cell bodies. SYN: r. of medulla oblongata.- r. musculi iliococcygeus [TA] SYN: iliococcygeal r..- r. palati [TA] SYN: palatine r..- palatine r. [TA] a rather narrow, low elevation in the center of the hard palate that extends from the incisive papilla posteriorly over the entire length of the mucosa of the hard palate. SYN: r. palati [TA], palatine ridge.- r. of penis [TA] the continuation of the r. of the scrotum onto the underside of the penis. SYN: r. penis [TA], penile r..- perineal r. [TA] the central anteroposterior line of the perineum, most marked in the male, being continuous with the r. of the scrotum. SYN: r. perinei [TA].- r. perinei [TA] SYN: perineal r..- pharyngeal r. [TA] the central line of the pharynx posteriorly where the muscular fibers meet and partly interlace. SYN: r. pharyngis [TA].- r. pharyngis [TA] SYN: pharyngeal r..- r. pontis [TA] the continuation of the r. medullae oblongatae into the pars dorsalis (or tegmentum) pontis. SYN: r. of pons.- pterygomandibular r. [TA] a tendinous thickening of the buccopharyngeal fascia, separating and giving origin to the buccinator muscle anteriorly and the superior constrictor of the pharynx posteriorly. SYN: r. pterygomandibularis [TA], pterygomandibular ligament.- r. pterygomandibularis [TA] SYN: pterygomandibular r..- r. retinae the horizontal line separating the superior and inferior portions of the temporal retina over which the retinal nerve fibers do not course.- r. of scrotum [TA] 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. SYN: r. scroti [TA], scrotal r., Vesling line.- Stilling r. the transverse interdigitations of fiber bundles across the anterior median fissure of the medulla oblongata at the decussation of the pyramidal tracts.

ra·phe also rha·phe 'rā-fē n the seamlike union of the two lateral halves of a part or organ (as of the tongue, perineum, or scrotum) having externally a ridge or furrow and internally usu. a fibrous connective tissue septum* * *
n.a line, ridge, seam, or crease in a tissue or organ, especially the line that marks the junction of two embryologically distinct parts that have fused to form a single structure in the adult. For example, the raphe of the tongue is the furrow that passes down the centre of the dorsal surface of the tongue.* * *
ra·phe (raґfe) gen. raphēs pl. raґphae [Gr. rhaphē] a seam; in anatomy, the line of union of the halves of any of various symmetrical parts.
