  • Each utricle has about 30'000 hair cells, and each saccule about 16'000. (wikibooks.org)
  • This causes the cells to be chemically elongated and shrunk (somatic motor), and hair bundles to shift which, in turn, electrically effects the basilar membrane's movement (hair-bundle motor). (wikipedia.org)
  • The type of motion or attitude detected by a hair cell depends on its associated mechanical structures, such as the curved tube of a semicircular canal or the calcium carbonate crystals (otolith) of the saccule and utricle. (wikipedia.org)
  • Among these are hair cells, pillar cells, Boettcher's cells, Claudius' cells and Deiters' cells (phalangeal cells). (wikipedia.org)
  • The stimulation of the hair cells sends the message to the brain that acceleration is taking place. (wikipedia.org)
  • The hair cells are arranged in four rows in the organ of Corti along the entire length of the cochlear coil. (wikipedia.org)
  • The outer hair cells, instead, mainly receive neural input from the brain, which influences their motility as part of the cochlea's mechanical pre-amplifier. (wikipedia.org)
  • thousands of hair cells sense the motion via their stereocilia, and convert that motion to electrical signals that are communicated via neurotransmitters to many thousands of nerve cells. (wikipedia.org)
  • nuclei
  • Cytokinesis results in distribution of chromosomes (nuclei in pink) and cytoplasm with organelles (yellow) between daughter cells, thus completing the mitotic cycle. (rupress.org)
  • This is seen in anterior (ventral) horn cells or certain cranial nerve nuclei. (wikipedia.org)
  • outer
  • There are two different skeletal types: the exoskeleton, which is the stable outer shell of an organism, and the endoskeleton, which forms the support structure inside the body. (wikipedia.org)
  • apical

  • organs
  • In metazoans, where cells divide in a context of germ layers, tissues, and organs, cell proliferation must be coordinated with differentiation to prevent developmental abnormalities. (rupress.org)
  • They function to move, support, and protect the various organs of the body, produce red and white blood cells and store minerals. (wikipedia.org)
  • nerve
