| mammary ridge | Bandlike thickening of ectoderm in the embryo extending on either side from just below the axilla to the inguinal region; in human embryos, the mammary glands arise from primordia in the thoracic part of the ridge, the balance of the ridge disappearing; in some lower mammals which give birth to a litter of young, several milk glands develop along these lines. Synonym: mammary fold, milk line, milk ridge. (05 Mar 2000) |

| marginal ridge | The rounded borders which form the mesial and distal margins of the occlusal surface of a tooth. Synonym: crista marginalis, marginal ridge. (05 Mar 2000) |
| genital ridge | An elevation of thickened mesothelium and underlying mesenchyme on the ventromedial border of the embryonic mesonephros; the primordial germ cells become embedded in it, establishing it as the primordium of the testis or ovary. Synonym: genital ridge. (05 Mar 2000) |
| Passavant's ridge | A prominence on the posterior wall of the naso-pharynx formed by contraction of the superior constrictor of the pharynx during swallowing. Synonym: Passavant's bar, Passavant's pad, Passavant's ridge. (05 Mar 2000) |
| medial epicondylar ridge | The distal sharp portion of the medial margin of the humerus. Synonym: crista supracondylaris medialis, medial epicondylar crest, medial epicondylar ridge, medial supracondylar crest. (05 Mar 2000) |
| medial supracondylar ridge | The distal sharp portion of the medial margin of the humerus. Synonym: crista supracondylaris medialis, medial epicondylar crest, medial epicondylar ridge, medial supracondylar crest. (05 Mar 2000) |
| pectoral ridge | The ridge below the greater tubercle of the humerus into which the pectoralis major muscle inserts. Synonym: crista tuberculi majoris, bicipital ridges, pectoral ridge. (05 Mar 2000) |
| gluteal ridge | The point of insertion on the upper portion of the shaft of the femur of the greater part of the gluteus maximus muscle; when markedly developed this tuberosity is called the third trochanter. Synonym: trochanter tertius, tuberositas glutea, crista glutea, gluteal crest, gluteal ridge. (05 Mar 2000) |
| residual ridge | That portion of the processus alveolaris remaining in the edentulous mouth following resorption of the section containing the alveoli. (05 Mar 2000) |
| centre of ridge | The buccolingual midline of the residual ridge. (05 Mar 2000) |
| gonadal ridge | An elevation of thickened mesothelium and underlying mesenchyme on the ventromedial border of the embryonic mesonephros; the primordial germ cells become embedded in it, establishing it as the primordium of the testis or ovary. Synonym: genital ridge. (05 Mar 2000) |
| mesonephric ridge | A ridge which, in early human embryos, comprises the entire urogenital ridge; however, later in development a more medial genital ridge, the potential gonad, is demarcated from it. See: urogenital ridge. Synonym: mesonephric fold. (05 Mar 2000) |
| ridge | 1. A (usually rough) linear elevation. See: crest. 2. In dentistry, any linear elevation on the surface of a tooth. 3. The remainder of the alveolar process and its soft tissue covering after the teeth are removed. Origin: A. S. Hyrcg, back, spine (05 Mar 2000) |
| ridge extension | An intraoral surgical operation for deepening the labial, buccal, and/or lingual sulci; it is performed to increase the intraoral height of the alveolar ridge in order to assist denture retention. (05 Mar 2000) |
| ridge relation | The positional relation of the mandibular ridge to the maxillary ridge. (05 Mar 2000) |
