Umbo


Definition:

  • (n.) The boss of a shield, at or near the middle, and usually projecting, sometimes in a sharp spike.
  • (n.) A boss, or rounded elevation, or a corresponding depression, in a palate, disk, or membrane; as, the umbo in the integument of the larvae of echinoderms or in the tympanic membrane of the ear.
  • (n.) One of the lateral prominence just above the hinge of a bivalve shell.

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.
  • (2) The bending will also affect the displacements transmitted to the ossicular load, and introduce significant errors into estimates of such displacements based on measurements of umbo displacement even at frequencies as low as a few kHz.
  • (3) The umbo region may represent the center of superficially radial dispersion.
  • (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.

  • (9) The acoustically estimated "drum location" generally lay between the optically determined vertical planes containing the TOD and the umbo.
  • (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.
