(FISH your): A thin but deep linear split in the epidermis that extends into the dermis. Severe dry skin can have fissures.

A conduit in a magma chamber in the shape of a long crack through which magma rises and erupts at the surface.
Latin = a cleft.
Elongated fractures or cracks on the slopes of a volcano. Fissure eruptions typically produce liquid flows, but pyroclastics may also be ejected.
A narrow crack or deep groove.
A crack or fracture in a subsurface formation.
A relatively wide planar opening in bedrock that originated as a fracture or fault. The opening may be partially or totally filled with soil or, if open, can act as a conduit for flowing water.
An open crack in rock or soil.
An elongate groove or opening.
An elongated cavity, usually the result of a cleavage opening to the surface of a diamond or gemstone.
a roughly linear or sinuous crack or opening on a volcano; a type of vent which commonly produces lava fountains and flows
a long narrow depression in a surface
break into fissures or fine cracks
a cleavage or fracture that is open at the surface as a long cavity
a crack in a rocks
a crack in the lining of the anal opening
a crack in the skin extending down to the corium and usually located in the folds of the skin over the joints

a very deep groove
A crack or fracture in the Earth's crust or the slope of a volcano, up which magma may rise.
An open crack in the rock
a crack in Earth's surface through which volcanic materials can escape.
an anatomic groove in the chewing surface of a tooth
An extensive crack, break, or fracture in the rock.
painful, linear ulcer of groove a the margin of the anus
crack or slit occurring in the mucous membrane of the anus; anal fissures are very painful and difficult to heal
A furrow in the brain, either produced by clefts between the embryonic vesicles, or of such depth and structure as to involve the entire wall of the hemispheres, or to produce eminences upon the walls of the lateral ventricles.
A groove or slit on the body or in an organ
Crack or groove in tissue
a fracture or crack in rock along which there is a distinct separation. It is often filled with mineral-bearing material.
A groove or natural division, deep furrow in the brain.
Elongate, narrow fractures.
A crack, gletz, feather, possibly reaching to the surface.
Longitudinal crack through only one surface of a bone.
a groove, crack, or natural division
a crack or tear in the skin or a mucous membrane.
A cleft or groove, normal or otherwise. When one occurs in the pars interarticularis, the yoke of bone connecting the right and left facets, the condition is known as spondylolysis. When discs become old, less firm and less elastic, they begin to tear and create fissures in parts of the disc, through which the nucleus can seep out and cause problems.
A deep furrow, cleft, or slit.
a crack or split in the skin, usually in the area of the anus.
A narrow slit.

A deep crevice in the skin around the anus, which makes bowel movement painful.
An extensive crack, break or fracture in rocks.
A fissure is a major physical division of the brain. The Lateral or Sylvian Fissure divides the Temporal and Frontal Lobes. A fissure is much deeper than a sulcus and the faces on either side of a fissure have have the same features (such as gyri and sulci) that occur on the outer surfaces of the brain.
Deep grooves in the cerebral hemispheres. See sulcus.
A cleft or groove. A fissure can be normal or abnormal. See the entire definition of Fissure

A fracture or crack in the surface of a stone.
An extensional crack, break, or fracture in the rocks.
