What's the difference between striation and striction?
Striation
Definition:
(n.) The quality or condition of being striated.
(n.) A stria; as, the striations on a shell.
Example Sentences:
(1) We show that over a limited range of high spatial frequencies this noise takes on a striated appearance, with the striations running perpendicular to the true fringe orientation.
(2) Cytoplasmic striations seen by light microscopy and trilamellar inclusions seen by electron microscopy were found in ballooned adrenocortical cells.
(3) In addition the bare central backbone showed transverse striations.
(4) These vacuoles contained one or several typical collagen fibrils and had either an electron-lucent matrix or contained an electron-dense material obscuring the fibrillar outlines and cross-striations.
(5) A new optical-electronic method has been developed to detect striation spacing of single muscle fibers.
(6) Fungiform papillae which had a round depression on the top were distributed sporadically among the filiform papillae, and contained columnar CTC with several plane striations running longitudinally along the lateral surface.
(7) Often juxtaposing sets of striations are not in correct register with respect to one another.
(8) In the Colobinae striations are oriented in a predominantly mesiodistal direction.
(9) Superficial corneal epithelial striations described as fibrillary lines have been documented as a common finding in normal and keratoconic eyes.
(10) A characteristic 67 nm transverse striation produced by the intermixing of tropocollagen and collagen types 1 and 3 is observed.
(11) These masses were classified into three broad categories: centrally necrotic masses with a large predominantly liquefactive center and higher density periphery (29); multilocular, septated masses with distinct linear bands or striations (21); and miscellaneous masses (9).
(12) These transition cells possessed apical granules of variable size as well as prominent basal striations.
(13) Amino acid composition, cross striation banding as observed using electron microscopy, cyanogen bromide peptide patterns in disc electrophoresis gels and resistance of the disulfide regions to pepsin digestion indicated a close similarity to previously described insoluble type III collagen, which was solubilized by limited pepsin digestion.
(14) Rabbits were trained to discriminate between vertical and horizontal striations.
(15) These structures were labelled with a selective antibody and showed regular periodic striation with repeats of approximately 40 nm.
(16) Sometimes, these seemed to be connected with the wall of the intracristal space by fine, electron-dense cross-striations.
(17) In the angiograms, the highly vascular region displays a certain striation which is due to the presence of muscle fiber bundles running between the pathologic vessels.
(18) However, in the clinical setting of acute cholecystitis, the presence of striations suggests gangrenous changes in the gallbladder.
(19) A- and I-band striation positions have been obtained, three-dimensionally reconstructed, and statistically analyzed from the volumes of resting isolated heart cells.
(20) Striation of the cuticle cells was normal, with wearing of their free borders (PL, SEM; fig.
Striction
Definition:
(n.) The act of constricting, or the state of being constricted.
Example Sentences:
(1) Only atropine inhibited nicotine-induced hypersecretion and bronchocon-striction.
(2) Re-examination revealed striction of the diaphragmatic movement in 11 cases.
(3) Nicotine increased mucus secretion from tracheal submucosal glands and caused bronchocon-striction.
