n.
1. A curve, turn, or fold, such as a bend in a tubular organ: a flexure of the colon.
2. The act or an instance of bending or flexing; flexion.

flexure

A bend, curve, angle or fold. The hepatic flexure in the large intestine (colon) is the angle near the liver between the vertical ascending colon and the roughly horizontal transverse colon.

[L. flexura]

flexure (flek´shur),

n the quality or state of being flexed.
flexure, clasp,
n the flexure of a retentive clasp arm to permit passage over the surveyed height of contour, thus permitting the seating or removal of the clasp.
flexure, mandibular,
n the change in shape of the mandible caused by the pterygoid muscles contracting during opening and protrusion movements.

flexure

a bend or fold; a curvation.

brain flexure
as head folding occurs in the developing embryo midbrain; cervical and pontine flexures also occur in the brain.
caudal flexure
the bend in the lumbosacral region of the embryo.
cephalic flexure
the curve in the midbrain of the embryo.
cervical flexure
a bend in the neural tube of the embryo at the junction of the brain and spinal cord.
cranial flexure
the anterior of the two ventral flexures of the developing embryo.
diaphragmatic flexure
the flexure between the left and right dorsal colons in the horse.
pelvic flexure
where the left ventral colon in the horse is flexed upward to become the left dorsal colon; there is a sharp reduction in the diameter of the colon at this flexure and the contents become much firmer, less fluid.
sigmoid flexure
the flattened loop of colon, immediately succeeding the cecum in ruminants.
sternal flexure
where the right ventral colon in the horse turns to become the left ventral colon.
