dental ridge

ridge (rij) a linear projection or projecting structure; a crest.

---

dental ridge  any linear elevation on the crown of a tooth.

dermal ridges  cristae cutis.

genital ridge , gonadal ridge a bulge on the medial side of the embryonic mesonephros; the primordial germ cells become embedded in it, forming the primordium of the testis or ovary.

healing ridge  an indurated ridge that normally forms deep to the skin along the length of a healing wound.

interureteric ridge  a fold of mucous membrane extending across the bladder between the ureteric orifices.

mammary ridge  a ridge of thickened epithelium from axilla to groin on each side in the mammalian embryo, along which nipples and mammary glands develop, all but one pair usually disappearing in the human.

mesonephric ridge  the more lateral portion of the urogenital ridge, giving rise to the mesonephros.

rete ridges  inward projections of the epidermis into the dermis, as seen histologically in vertical sections.

synaptic ridge  a wedge-shaped projection of a cone pedicle or of a rod spherule, on either side of which lie the horizontal cells whose dendrites are inserted into the ridge.

urogenital ridge  a longitudinal ridge in the embryo, lateral to the mesentery, which later divides into the mesonephric and gonadal ridges.
