    • n symphysis In anatomy and zoology: The union or connection of bones in the middle line of the body, either by confluence, by direct apposition, or by the intervention of cartilage or ligament; also, the part, or configuration of parts, resulting from such union or connection. Symphysis usually constitutes an immovable joint, and may be so intimate that all trace of original separateness of the parts is lost. These two conditions are illustrated in the human body in the symphysis of the pubic bones and of the two halves of the lower jaw respectively; but in many animals symphyses remain freely movable, as in the two halves of the lower jaw of serpents. The term is chiefly restricted to the growing together or close apposition of two halves of a bilaterally symmetrical bone, or of a bone with its fellow of the opposite side—other terms, as ankylosis, synosteosis, synchondrosis, and suture, being applied in other cases. See cuts under innominatum and pelvis.
    • n symphysis Some point or line of union between two parts; a commissure; a chiasm: as, the symphysis of the optic nerves.
    • n symphysis Attachment of one part to another; a growing together; insertion or gomphosis with union: as, the symphysis of teeth with the jaw. See acrodont, pleurodont.
    • n symphysis Coalescence or growing together of parts so as to close a natural passage; atresia.
    • n symphysis In botany, a coalescence or growing together of similar parts.

    • n Symphysis sim′fi-sis the union of two parts of the skeleton, either by confluence, by direct apposition, or by the intervention of cartilage or ligament: the union of parts normally separate, coalescence or growing together of parts
