Example Sentences:
(1) The position, displacement and phase angle of the rotation axis of the ossicles was calculated based on the displacement and phase angle of the umbo, malleus head and lenticular process.

(4) The epithelial migration center was found at the region of umbo, manubrium, and the short process of the malleus.
(5) It is demonstrated that the rotation angels can not account for the measured movement of the umbo, which leads to the conclusion that for static high pressure levels the classical hypothesis of rotation around a fixed axis has to be abandoned.
(6) There is a small area we have termed the "slow zone", located anterior and inferior to the umbo, that has comparatively fewer patches and where ink dots can remain static for several weeks.

(10) The displacement of the umbo is compared to other work.
(11) All of the modifications (except the perforation) had a minimal effect on umbo displacement; this seems to imply that the pars flaccida has a minor acoustic role in human beings.
(12) Due to the gliding movement in the malleus-incus joint, this motion changes at the umbo into outward rotation, counteracting the tensor tympani muscle.
(13) When the motion is rotational the position of the axis of rotation shifts with frequency, the shifts are so large that the axis can lie near the umbo so that amplitudes at the processus lateralis are larger than at the umbo.
(14) The umbo moved piston-like at 0.1-0.8 kHz and 2.6-4.5 kHz but in an ellipse at 1.0-2.4 kHz.
(15) The vibration amplitude and phase angle of the umbo, malleus head, lenticular process and stapes head were measured at 19 frequencies between 0.1 kHz and 4.5 kHz.
(16) The malleus head showed elliptical movement with its long axis anteriorly tilted around 45 degrees from the direction of the umbo vibration at 0.1 kHz.
(17) As a result of the bending, the frequency response at the umbo at high frequencies displays much higher amplitudes and larger phase lags than when the manubrium is rigid.
(18) The effects of aditus blockage, decrease of tympanic cavity volume, and resection of the tensor tympani muscle on umbo displacement were studied in human temporal bones using a new non-contacting video measuring system.
(19) The umbo, lenticular process and stapes head vibrated parallel at lower frequencies.
(20) The three-dimensional movements of the umbo, the proc.

(4) This treatment is usually well tolerated but not devoid of systemic effects.
(5) Findings on plain X-ray of the abdomen, using the usual parameters of psoas and kidney shadows in the Nigerian, indicate that the two communities studied are similar but urinary calculi and urinary tract distortion are significantly more prominent in the community with the higher endemicity of urinary schistosomiasis.
(6) As May delivered her statement in the chamber, police helicopters hovered overhead and a police cordon remained in place around Westminster, but MPs from across the political spectrum were determined to show that they were continuing with business as usual.
(7) Chloroquine induced large cytoplasmic vacuoles, whereas the other drugs (quinacrine, 4,4'-diethylaminoethoxyhexestrol, chlorphentermine, iprindole, 1-chloro-amitriptyline, clomipramine) caused formation of lamellated or crystalloid inclusions as usually seen in drug-induced lipidosis.
