- r. scroti [TA] SYN: r. of scrotum.

- 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

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.
