Ray-finned fishes actively control the shape and orientation of their fins to either generate or resist hydrodynamic forces. Because of the emergent mechanical properties of their segmented, bilaminar fin rays (lepidotrichia), and actuation by multiple muscles, fish can control the rigidity and curvature of individual rays independently, thereby varying the resultant forces across the fin surfa...

33 34 The plainfin midshipman fish, Porichthys notatus, is a seasonally breeding species of marine teleost fish that 35 generates acoustic signals for intraspecific social and reproductive-related communication. Female midshipman 36 use the inner ear saccule as the main acoustic endorgan for hearing to detect and locate vocalizing males that 37 produce multiharmonic advertisement calls during t...

Our senses of hearing and balance depend upon hair cells, the sensory receptors of the inner ear. Millions of people suffer from hearing and balance deficits caused by damage to hair cells as a result of exposure to noise, aminoglycoside antibiotics, and antitumor drugs. In some species such damage can be reversed through the production of new cells. This proliferative response is limited in ma...

Approximately 80 years ago John Tait speculated about a possible auditory role for the otolith organs in humans those days, there was no direct evidence for that idea. This time is for us to review and research. Then, the objective of our study was to investigate saccular hearing in healthy adults. We selected twenty healthy controls and twenty-four dizzy cases. Assessment comprised of audiolog...

INTRODUCTION Ménière's disease (MD) is an inner ear disorder characterized by episodic vertigo, tinnitus, ear fullness, and fluctuating hearing. Its diagnosis can be especially difficult in cases where vestibular symptoms are present in isolation (vestibular MD). The definitive diagnosis is made histologically and can only be performed post-mortem, after analysis of the temporal bone. Endolymph...

2764 Abstract. – OBJECTIVE: The factors influencing the diagnosing of salpingemphraxis by X-ray hysterosalpingography (HSG) are identified and summarized, to provide a reference for improving the precision of the diagnosis procedure. PATIENTS AND METHODS: In order to analyze the collected data, the methods of stratified sampling and retrospective analysis were adopted. Two county-level medical ...

normal 0 false false false en-us x-none ar-sa laryngocele is an air-filled, abnormal dilation of the laryngeal saccule that extends upward within the false vocal fold, in communication with the laryngeal lumen. a case of 43-year-old male with bilateral internal laryngoceles, who has been treated as asthma for 4 years, is presented. the patient had dyspnea, cough, and excessive phlegm for a mont...

Background: Reports vary on the incidence of vestibular dysfunction and dizziness in patients following cochlear implantation (CI). Disequilibrium may be caused by surgery at base, leading to functional disturbances receptors endolymphatic duct system (EDS) which are located nearby. Here, we analyzed three-dimensional (3D) anatomy this region, aiming optimize surgical approaches limit damage or...
