• nerves to the utricle
  • The portion above the crista falciformis presents behind, the area cribrosa superior, pierced by a series of small openings, for the passage of the nerves to the utricle and the superior and lateral semicircular ducts, and, in front, the area facians, with one large opening, the commencement of the canal for the facial nerve (aquæductus Fallopii). (wikipedia.org)
  • auditory
  • Research has shown, like songbirds, females in some species of fish show seasonal variation in auditory processing and the sensitivity of the saccule of females peaks during the breeding season. (wikipedia.org)
  • maculae
  • 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)
  • outer
  • 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)
  • The outer ear is the external portion of the ear and includes the fleshy visible pinna (also called the auricle), the ear canal, and the outer layer of the eardrum (also called the tympanic membrane). (wikipedia.org)
  • Two sets of muscles are associated with the outer ear: the intrinsic and extrinsic muscles. (wikipedia.org)
  • The great auricular nerve, auricular nerve, auriculotemporal nerve, and lesser and greater occipital nerves of the cervical plexus all supply sensation to parts of the outer ear and the surrounding skin. (wikipedia.org)
  • On the outer surface, the petrosal provides attachment areas for the muscles and ligaments of the ear ossicles. (2dgf.dk)
  • ossicles
  • The middle ear contains the three small bones-the ossicles-involved in the transmission of sound, and is connected to the throat at the nasopharynx, via the pharyngeal opening of the Eustachian tube. (wikipedia.org)
  • 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)
  • branches
  • Pain and temperature sensitivity is checked from up to down (in the zones of the three branches of the nerve), and from the ear to the nose (in the zones of segmental innervations zone of Zeldera). (scribd.com)
  • 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)
  • 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)
  • 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)
  • symptoms
  • It may present with bilaterally symmetrical symptoms, or asymmetrically, with one ear developing the condition after the other or not at all. (wikipedia.org)
  • small
  • 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)
  • often
  • 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)
