  • outer ear
  • In mammals, the ear is usually described as having three parts-the outer ear, middle ear and the inner ear. (wikipedia.org)
  • Since the outer ear is the only visible portion of the ear in most animals, the word "ear" often refers to the external part alone. (wikipedia.org)

  • inner ears
  • We therefore set out to develop a fast and reliable approach for detailed 3D visualization of whole inner ears as well as maculae. (biomedcentral.com)
  • PTA staining and subsequent high-resolution contrast enhanced microCT imaging is a powerful method to obtain 3D models of fish inner ears and maculae in a fast and more reliable manner. (biomedcentral.com)
  • Future studies investigating functional morphology, phylogenetic potential of inner ear features, or evolution of hearing and inner ear specialization in fishes may benefit from the use of 3D models of inner ears and maculae. (biomedcentral.com)
  • Inner ears in modern bony fishes (Teleostei) are composed of three semicircular canals and three otolithic end organs. (biomedcentral.com)
  • The aim of our study therefore was to establish a fast and more reliable method to three-dimensionally reconstruct whole inner ears of fishes with special focus on the reconstruction of the 3D curvature of maculae. (biomedcentral.com)
  • Our results indicate that reliable 3D reconstructions of inner ears including otoliths and maculae can be obtained by using high-resolution microCT imaging of specimens stained with phosphotungstic acid. (biomedcentral.com)
  • mammals
  • The ear is the organ of hearing and, in mammals, balance. (wikipedia.org)
  • A tubercle, known as Darwin's tubercle, is sometimes present, lying in the descending part of the helix and corresponding to the ear-tip of mammals. (wikipedia.org)
  • The inner ear of Mesozoic mammals has been described in a few papers, Morganucodon by Graybeal et al. (2dgf.dk)
  • head
  • The ears of vertebrates are placed somewhat symmetrically on either side of the head, an arrangement that aids sound localisation. (wikipedia.org)
  • The saccule, like the utricle, provides information to the brain about head position when it is not moving. (wikipedia.org)
  • connects
  • The middle ear also connects to the upper throat at the nasopharynx via the pharyngeal opening of the Eustachian tube. (wikipedia.org)
  • muscles
  • The ear muscles are supplied by the facial nerve, which also supplies sensation to the skin of the ear itself, as well as to the external ear cavity. (wikipedia.org)
  • includes
  • Another category of medications includes drugs, over the counter ear drops and solutions which are quite significant in clearing or treating the symptoms some infections. (knowfacts.org)
  • brain
  • The brain accomplishes this by comparing arrival-times and intensities from each ear, in circuits located in the superior olivary complex and the trapezoid bodies which are connected via pathways to both ears. (wikipedia.org)
  • Symptoms
  • Learn about outer, middle and inner symptoms of ear infection in adults, what treatment, medicines or cure for adults to use. (knowfacts.org)
  • Ear problems and infections tend to have signs and symptoms which cut across the outer, middle or inner ear. (knowfacts.org)
  • Whether they are outer, middle or inner ear infection symptoms - they come and go. (knowfacts.org)
  • It may present with bilaterally symmetrical symptoms, or asymmetrically, with one ear developing the condition after the other or not at all. (wikipedia.org)
  • develops
  • The ear develops from the first pharyngeal pouch and six small swellings that develop in the early embryo called otic placodes, which are derived from ectoderm. (wikipedia.org)
  • infection
  • The ear may be affected by disease, including infection and traumatic damage. (wikipedia.org)
  • Are you an adult with ear infection problems or complications i.e. ear infection in an adult problem? (knowfacts.org)
  • While looking at causes of ear infections in adults, a breakdown of ear parts should be necessary for a better understanding, comparison and analysis i.e. outer, middle and inner ear infection causes. (knowfacts.org)
  • More bacterial infections of the ear are treatable as well as those caused by a fungus infection. (knowfacts.org)
  • different
  • It is different than VNG because instead of using temperature changes to stimulate the inner ear, whole body rotations are used instead. (ucsf.edu)
  • surgical
  • The ear has been adorned by earrings and other jewellery in numerous cultures for thousands of years, and has been subjected to surgical and cosmetic alterations. (wikipedia.org)
  • Any sort of problems could be in form of injury after fall, physical damage or certain surgical procedures operated on an outer and inner ear. (knowfacts.org)
  • shown
  • This in turn means that orientation patterns are obtained, shown, and compared between species in a purely two dimensionally way irrespective of the natural curvature of the maculae in the ear. (biomedcentral.com)
  • damage
  • Cranial nerve VIII, is the least affected component of the ear when ototoxicity arises, but if the nerve is affected, the damage is most often permanent. (wikipedia.org)
