The dynamic characteristic of in-vivo human ossicles
نویسندگان
چکیده
The study was to analyze the dynamic characteristics of ossicles under the stimulus frequencies, 125 Hz, 250 Hz, 500 Hz, 750 Hz, 1 kHz, 2 kHz, 3 kHz, 4 kHz, 5 kHz, 6 kHz, 7 kHz and 8 kHz, by finite element method. The finite element model of the ossicles chain of patients could be built by 3D image model of the ossicles based on the high resolution computed tomography. The displacement at the footplate would hardly occur when the ossicles was excited by the sound stimuli at frequency above 2 kHz. The presented result shows that the ossicles only could transmit the stimuli under 2000 Hz by the vibration of ossicles.

The natural vibration characteristics of human ossicles.
BACKGROUND Recently, a model of the ossicular chain for finite element analysis has been developed. However, the natural vibration characteristics of human ossicles have never been studied. Herein, we investigated the dynamic characteristics of the coupling of in-vivo ossicles using finite element analysis. METHODS The geometry of the ossicular chain was obtained by high-resolution computed t...
متن کاملP-120: Meiotic Spindle Visualization and Zona Pellucida Birefringence in Relation to Morphology of In Vivo and In Vitro Matured Human Oocytes of In Vivo and In Vitro Matured Human Oocytesof In Vivo and In Vitro Matured Human Oocytes
Background: The meiotic spindle plays an important role in the oocyte during chromosome alignment and separation at meiosis. The zona pellucid (ZP) is a dynamic matrix composed of filaments with the properties that might reflect the history of oocyte cytoplasmic maturation. Since, spindle and ZP in living oocytes are highly birefringent, their structures can be viewed noninvasively by using a P...
متن کاملHuman umbilical cord blood-borne fibroblasts contain marrow niche precursors that form a bone/marrow organoid in vivo.
Human umbilical cord blood (CB) has attracted much attention as a reservoir for functional hematopoietic stem and progenitor cells, and, recently, as a source of blood-borne fibroblasts (CB-BFs). Previously, we demonstrated that bone marrow stromal cell (BMSC) and CB-BF pellet cultures make cartilage in vitro Furthermore, upon in vivo transplantation, BMSC pellets remodelled into miniature bone...
متن کاملAnatomical and morphometrical study of middle ear ossicles in 2 to 3-month-old Makouei sheep fetuses
The middle ear ossicles are important due to transmission of sound to the inner ear leading to sound understanding. The aim of present study was to determine the anatomical and morphometrical aspects of middle ear ossicles in Makouei sheep fetuses. For this experimental study, eight sheep fetuses at the age of 2 to 3 months were provided from public slaughterhouse; their middle ear ossicles wer...
متن کاملMorphometrical Study of the Temporal Bone and Auditory Ossicles in Guinea Pig
In this research, anatomical descriptions of the structure of the temporal bone and auditory ossicles have been performed based on dissection of ten guinea pigs. The results showed that, in guinea pig temporal bone was similar to other animals and had three parts; squamous, tympanic and petrous .The tympanic part was much better developed and consisted of oval shaped tympanic bulla with many re...
