ridge (rij) a linear projection or projecting structure; a crest.
ridge [rij]
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.
| genital ridge n. See gonadal ridge. |
ridge [rij]
a linear projection or projecting structure; a crest.
alveolar ridge a bony ridge of the maxilla or mandible, the part of the alveolar process that contains the alveoli; called also alveolar crest.
dental ridge any linear elevation on the crown of a tooth.
Dental ridges in a maxillary molar. From Dorland's, 2000.
dermal r's ridges of the skin produced by the projecting papillae of the corium on the palm of the hand and sole of the foot, producing a fingerprint and footprint characteristic of the individual; called also cristae cutis.
genital ridge the more medial part of the urogenital ridge, giving rise to the gonad.
healing ridge an indurated ridge that normally forms deep to the skin along the length of a healing wound.
incisal ridge the part of the crown of an anterior tooth that makes up the actual incisal portion; see incisal surface, under surface.
interureteric ridge a fold on mucous membrane extending across the bladder between the ureteric orifices.
mammary ridge an ectodermal thickening in early embryos, along which the mammary glands subsequently develop.
mesonephric ridge the more lateral portion of the urogenital ridge, giving rise to the mesonephros.
oblique ridge a variable linear elevation obliquely crossing the occlusive surface of a maxillary molar.
urogenital ridge a longitudinal ridge in the embryo, lateral to the mesentery.
genital
pl. genitalia
1. pertaining to reproduction, or the reproductive organs.
2. genitals, the reproductive organs, especially the external genital organs.
genital bursatti
see swamp cancer.
genital campylobacteriosis
see bovine vibriosis.
genital ducts
male—efferent ductules, ductus epididymis, ductus deferens; female—uterine tubes (fallopian tubes, oviducts), uterus, vagina.
genital lock
the joining together of the dog and the bitch during coitus in which the enlarged penile bulb of the dog is held tightly in the bitch's vagina. The dog normally dismounts and stands back-to-back with the bitch, with the penis still locked in the vagina. Called also the 'tie'.
genital mycoplasmosis
see granular vaginitis.
genital ridge
bilateral thickenings in the roof of the embryo's celom which are the primordia of the gonads.
genital squamous cell carcinoma
squamous cell carcinoma of the penis and prepuce and of the vulva.
genital system
the reproductive system including ovaries, ovarian bursa, uterine tubes, uterus, cervix, vagina, vulva, vestibular glands of the female and testicles, epididymis, vas deferens, penis, prostate, seminal vesicles, bulbourethral glands, prepuce and scrotum of the male.
genital tract
from the ovaries to the vulva, from the testicles to the external urethral meatus.
genital tubercle
the eminence in the embryo which develops into the clitoris or penis.
genital-urinary system
the combined urinary and reproductive systems.
genital vibriosis
see bovine vibriosis.
genital warts
