What's the difference between cingulum and clitellus?
Cingulum
Definition:
(n.) A distinct girdle or band of color; a raised spiral line as seen on certain univalve shells.
(n.) The clitellus of earthworms.
(n.) The base of the crown of a tooth.
Example Sentences:
(1) Two-dimensional photoelastic analysis of resin-bonded cingulum rest seats demonstrated improvement in stress distribution when the lingual surface of the tooth was prepared with a cingulum groove.
(2) Injection of lidocaine into the anterior cingulum bundle produced a significant reduction in formalin pain scores, but had no effect on foot-flick latencies.
(3) The ventral portion of the cingulum (ligamenta pubourethralia posteriora and ligamentum pubourethrale intermedium) is especially important, as it provides an anchor of the vesical cervix as a mark of continence.
(4) The lesions are characteristically localized in the "centro-axial" regions of the brain involving most frequently: corpus callosum, septum pellucidum, fornix, tela chorioidea, peri- and para-ventricular zone, infundibulobasal region and cingulum; this pattern also includes lesions of the hippocampal area, upper brainstem, pontocerebellar complex, and parasagittal areas of the cerebrum.
(5) The data indicated that the control-lesion and cingulum groups did not differ in the acquisition or extinction of an AAR.
(6) The prefrontal, cingulate, and parahippocampal (entorhinal) cortex, as well as the perforant pathway, cingulum bundle, and hippocampus, were closely examined because these regions have recently been found to show various neuropathological differences in schizophrenia.
(7) From a functional anatomic standpoint every precise surgical technique for incontinence must take the cingulum vesicae and the adjacent structures into consideration.
(8) Locus coeruleus (LC) fibers in the fornix mainly innervate the septal pole of the dentate gyrus, whereas the cingulum projects to the ventral hippocampal formation to provide LC input to the dentate gyrus.
(9) Furthermore, these findings suggest that the cingulum is involved in the affective component of pain and that interruption of cingulum activity with lidocaine can produce analgesia.
(10) A cannula was stereotaxically implanted into the anterior cingulum on one side in anesthetized rats.
(11) nov. is distinguished by its larger size and differences of molar cusp acuity, buccal cingulum expression, and mental foramen configuration.
(12) In parallel with this decrease, numerous 5-HT-IR fibers in the cingulum bundle, fornix-fimbria and the hippocampal parenchyma exhibit structural changes, similar to those produced by 5,7-dihydroxytryptamine, a specific neurotoxin of the 5-HT system.
(13) Dense connective tissue forms a permanent link, adjacent to the cingulum vesicae, between the bladder on the one hand and the lateral pelvic wall and anterior surface of the uterus on the other; in this way the bladder is held in the pelvis at a particular point.
(14) They were treated by lesions in the anterior cingulum.
(15) The fascia endopelvina, extending into the bladder along the entire circumference between the corpus and fundus vesicae, represents the cingulum vesicae.
(16) Seven to 10 days after surgery, the rats were infused with 1 microliter of 2% lidocaine in saline or saline alone into the anterior cingulum bundle immediately prior to testing for analgesia in the formalin or foot-flick test.
(17) Evoked potentials (EPs) and neuronal responses of the medial (MPO) and lateral (LPO) preoptic region (RPO) and adjacent areas of the hypothalamus to stimulation of the prefrontal (area 8), cingulum (area 24), periamigdaloideus (RPA) cortex and hippocampus (area CA3) have been studied on cats anesthetized with ketamine.
(18) Neuroanatomical evidence suggests a separate role for the anterior and posterior cingulum.
(19) By 7 d of postnatal age all the vimentin+ cells were GFAP+ and had converged predominately on the cingulum.
(20) The cingulum group, however, showed a significant deficit in the acquisition of a PAR and a noticeably slower rate of lever pulling during avoidance trials in the combined avoidance training sessions.
Clitellus
Definition:
(n.) A thickened glandular portion of the body of the adult earthworm, consisting of several united segments modified for reproductive purposes.
