A gaping or bursting open along a definite line of attachment or suture, without tearing, as in the opening of pods, or the bursting of capsules at maturity so as to emit seeds, etc.; also, the bursting open of follicles, as in the ovaries of animals, for the expulsion of their contents.
The spontaneous opening of a closed structure, along certain lines or in definite a direction to release the contents
n. (L. dehiscere, to gape) opening and shedding contents; said of stamens and fruits.
the disruption of a surgical wound.
Opening or split of tissue as part of a natural developmental process (e.g. the rupture of anther sutures to release mature pollen).
an opening up, as in the Graafian follicle, a surgical wound, an embryonic vagina, etc.
Latin de = away, hiscere = to gape, hence, a separation, a splitting away.
to split open or rupture.
On African Violets, that part of the flower cycle when the anthers open up to release pollen.
Refers to fruits opening when ripe to release their seeds.
The opening of an ovary, anther-sac or sporange to emit the contents.
a wound that has split apart. A dehiscence in the exstrophy population typically means that the pubic bones and abdominal wall closure have split apart and the bladder is reexstruded onto the abdomen wall.
(a)Implant Dehiscence, a splitting open, a break in the covering epithelium leaving an isolated area of an implant exposed to the oral cavity. (b)Mandibular Dehiscence, exposure of inferior alveolar nerve caused by extreme resorption of the mandibular to the point that the roof of the mandibular canal is no longer covered with bone, leaving only soft tissue separa- ting the contents of the canal from the oral cavity.
the spontaneous split at maturity of a reproductive body to release enclosed seeds or spore.
(biology) release of material by splitting open of an organ or tissue; the natural bursting open at maturity of a fruit or other reproductive body to release seeds or spores or the bursting open of a surgically closed wound
The opening of an anther or fruit along a regular line(s) of cleavage.
the process of releasing spores. That is actually the botanical definition, although it is widely used in mycology. Dehiscence is also used in a more restricted, mycological sense to mean a process for realsing all of the spores in an ascocarp simultaneously, or in some coordinated manner.
the partial or total rupturing of a sutured wound; usually involves an abdominal wound in which the layers below the skin also separate
Separation of wound edges.
A rupture or splitting open, as of a surgical wound, or of an organ or structure to discharge its contents.
of the eucalypt flower bud, when the operculum sheds; of the anther, when the lobes open and shed the pollen; of the fruit, when the capsule splits and sheds the seed
opening or splitting of a fruit or anther
A splitting or gaping of the conjunctiva at a suture line or exposure of an implant.
The opening of an anther, fruit, or other structure to permit the escape of reproductive bodies.
The method or process of opening of a seed capsule or anther.
The fruit opens naturally (opposite remains closed at maturity ( indehiscent )
Breakdown of healing at a wound or suture site.
Dehiscence is the spontaneous opening at maturity of a plant structure, such as a fruit, anther, or sporangium, to release its contents.
