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.
