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.
