• rod cells
  8 March 2007

  The retina consists of three main cellular layers (right): a rod cells (R) and cone cells (C) layer or photoreceptor layer, a layer of interneurons (bipolar interneurons, horizontal interneurons, amacrine cells) and the ganglion cell layer, whose axons form the optic nerve, connecting retina and brain.
  The photoreceptors are oriented in the same plane as incoming light, which funnels through the inner to the OS.
  The outer segment contains a dense array of light-sensitive, hollow discs, (...)

  asymmetric division
  In the embryonic central nervous system of the fruit fly Drosophila, most neurons and glial cells are generated by asymmetric division of neural stem cells called neuroblasts.
  Several genes have been identified that are required for the establishment of neuroblast polarity, for the asymmetric segregation of cell fate determinants and for the proper orientation and geometry of the mitotic spindle.

  Definition: Parietal cells, or oxyntic cells, are the stomach epithelium cells that secrete gastric acid and intrinsic factor acetylcholine (M3 receptors) and gastrin (CCK2 receptors).
  The histamine receptors act by increasing intracellular cAMP, whereas the muscarinic and gastrin receptors increase intracellular Ca2+ levels.
  Both cAMP and Ca2+ act via protein kinases to increase the transport of acid into the stomach. (...)

• spermatid
  22 April 2011

  Definition: The spermatid is the haploid male gametid that results from division of secondary spermatocytes. As a result of meiosis, each spermatid contains only half of the genetic material present in the original primary spermatocyte.
  Spermatids are connected together by cytoplasmic material and have superfluous cytoplasmic material around their nuclei.
  When formed, early round spermatids must undergo further maturational events in order to develop into spermatozoa, a process termed (...)
