The forward f. of the embryo at the caudal portion, cephalic f's, cranial f's, encephalic f's

Certain f's of the cranial portion of the embryo which take place at an early period of development, the earliest and most important of which is the one that occurs at the anterior extremity of the notochord. hepatic f. of the colon. An abrupt bend in the ascending colon, situated at the under surface of the liver, on the right of the gall-bladder, where it pa es inward and to the left, to become the transverse colon. posterior f. of the corpus callosum. See splenium. principal cephalic f. A decided angular flexion of the cranial cavity of the embryo in a ventral, or downward, direction in the region of the midbrain and sella turcica, sigmoid f. of the colon. An S-shaped f. of the colon. It begins at the termination of the descending colon, at the margin of the crest of the ilium, and ends at the beginning of the rectum, opposite the left sacro-iliac synchondrosis. This portion of the colon retains its mesentery, and is completely invested with peritoneum. splenic f. of the descending colon. An abrupt bend connecting the transverse with the descending colon, and situated beneath the lower end of the spleen. [Lat, flectere, to bend.] Flindt's spots. Minute white or bluish white spots almost invariably to be found on the mucous membrane of the mouth before the occurrence of the rash of measles. flint disease. A form of chronic pulmonary disease prevalent among quarrymen; ascribed to the habitual inhalation of flinty dust. Flint's murmur. A rumbling m., limited in area, pre systolic, heard at the apex of the heart in some cases of aortic insufficiency; supposed to be caused by extreme dilatation of the ventricles in which the mitral segments remain in the blood current because during diastole they cannot be forced back against the wall. 1886.] I Austin Flint, Amer. physician, 18 12- floccular (flok'u-lar). 1.
