(a.) Resembling a ring; -- said esp. of the cartilage at the larynx, and the adjoining parts.
Example Sentences:
(1) A complete review of the literature was made which shows that most chondrosarcomas occur in middle-aged males originating most often from the posterior cricoid lamina, next from the thyroid cartilage.
(2) The complete thyroid cartilage is dissected out, and then a horizontal cut is made through the cricoid cartilage.
(3) Posterior subglottic extension of glottic carcinoma has been a contraindication for partial laryngectomy because of the proximity of the cricoid cartilage.
(4) In three dogs in which the attachments of the CT to either the thyroid or cricoid cartilage were severed, superior laryngeal nerve stimulation had no systematic effect on Ruaw.
(5) By stimulating the posterior laryngeal mucosa proximal to the cricoid edge, the RLN branch to the posterior cricoarytenoid muscle was activated, causing ipsilateral vocal cord abduction independent of frequency.
(6) Despite the possibility that cricoid pressure may have to be interrupted momentarily, the ease with which the technique can be learnt, and the immediate availability of the necessary apparatus suggest that it should be considered for inclusion in failed intubation drill.
(7) Cricoid pressure does not seem to result in significant damage in this situation.
(8) The use of the anterior cricoid split has allowed the extubation of multiple children who would otherwise require tracheostomy.
(9) The stenosis appeared to be caused by a specific change in the pattern of growth leading up to an anterior narrowing ('pear'-like) of the cricoid ring and a conspicuous thickening of the subepithelial layer.
(10) The anterior-posterior cricoid split group and the control group did not significantly differ with respect to any of the three parameters.
(11) Esophageal erosions of the mid third of the esophagus and on esophageal stricture at the level of the cricoid were diagnosed 16 days post ingestion.
(12) Mean static force values producing thyroid and cricoid cartilage fractures were 15.8 and 20.8 kg, respectively, and the similarity of this experimental injury to a mild clinical laryngeal fracture syndrome is discussed.
(13) Four minor clefts are reported, three cases of supraglottic interarytenoid cleft and one of partial cricoid cleft.
(14) At surgery, the mass was identified at the level of the cricoid cartilage, displacing the right lobe of the thyroid gland superiorly and extending posteriorly to the prevertebral fascia.
(15) However, scar bands of approximately the same width as the implant were responsible for cricoid diastasis in 23 cases.
(16) One patient had a direct laryngeal and a recurrent laryngeal nerve simultaneously, and one patient had a bifurcated recurrent laryngeal nerve with an accessory vagus nerve joining it 13.5 cm from the cricoid cartilage.
(17) Extensive stricture formation requires reconstruction to create a functional funnel system that empties below the cricoid.
(18) In one patient, resection of subtotal thyroid combined with trachea including a part of cricoid cartilage was performed, and followed with end to end anastomosis.
(19) This is a five-year follow-up on such a patient in whom ultimate reconstruction was accomplished by the use of mucous membrane from the maxillary sinus as a lining for the reconstructed larynx while costal cartilage provided additional supportive structural material for the compromised cricoid and thyroid cartilages.
(20) Successful insertion was achieved at the first or second attempt in 19 of the 22 patients in the non-cricoid pressure group, but in only three of the 20 patients in the cricoid pressure group (chi 2 18.62, P < 0.001).
Crinoid
Definition:
(a.) Crinoidal.
(n.) One of the Crinoidea.
Example Sentences:
(1) At 5 hr, gastrulation has occurred in the absence of any structure comparable to the echinoid hyaline layer; therefore, at least one important mechanism proposed for echinoid gastrulation cannot occur in this crinoid.
(2) This is done from a comparative perspective, with reference to members of the five extant echinoderm classes; crinoids, holothurians, asteroids, ophiuroids, and echinoids.
(3) Several species of fish are deterred from eating food by the inclusion in it of these sulphates at the concentration found in crinoids.
(4) We report the results of cutting experiments on embryos of the crinoid Florometra serratissima, which produce, in the doliolaria stage, a striped pattern of ciliary bands.
(5) We have examined echinoderms from the five existing classes (echinoids, asteroids, ophiuroids, holothurians and crinoids) for the expression of these specific phosphagen kinases in different tissues.
(6) The range of (presumed) polyketide constituents in comatalid crinoids has been extended to include bianthronyls, meso-naphthodianthrones and sulphate esters of various of the polyketides.
(7) In contrast, the obliquely striated fibres of crinoids show markedly continuous and homogeneous oblique Z-lines; such a structure is not compatible with 'super-performances' like sliding and shearing of the sarcomere elements, but instead could allow functions comparable to those characteristic of a cross-striated muscle (quick, short movements, mechanically amplifiable by bone levers).
