  • stria vascularis
  • however, studies indicate an earlier histological and immunohistological maturity in the dark-cell areas compared to the stria vascularis. (wikipedia.org)
  • macula
  • Morphological and immunohistochemical studies in several species have indicated that these dark cell areas also form a single layer resting on top of pigmented cells at the base of the cristae ampullaris in the semi-circular canals and around the utricular macula. (wikipedia.org)

  • Whereas the extrapyramidal system centers around the modulation and regulation through indirect control of anterior (ventral) horn cells. (wikipedia.org)
  • outer
  • Changes commonly observed in the outer ear of older individuals include an enlargement of the pinnae, an increase in cerumen (earwax) production in the ear canal, and a change in the cartilage support of the ear canals. (encyclopedia.com)
  • 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
  • The apical membranes of the dark cells also have a k+ channel which is formed of two subunits, the KCNE1 regulatory protein and the KCNQ1 channel proteins. (wikipedia.org)
  • cartilage
  • The skeleton, which forms the support structure inside the fish, is either made of cartilage, in cartilaginous fish, or bone in bony fish. (wikipedia.org)
  • 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)
