Until Berta and Ernst Scharrer established the concept of neurosecretion in 1928, scientists believed that either cells secreted hormones, which made them endocrine cells and thus part of the endocrine system, or conducted electrical impulses, in which case they were nerve cells and thus part of the nervous system.<\/address>\n\n\n\n

What does this sentence mean?<\/h2>\n\n\n\n

This sentence presents a few facts about the understanding of the cells in human body.  It states that in 1928 two scientists established a certain concept.  Before this concept of neurosecretion was established, scientists had a limited vision of the cells. Cell played one of the two roles:<\/p>\n\n\n\n

  1. secreted hormones, making them endocrine cells and hence part of the endocrine system<\/li>
  2. conducted electrical impulses, making them nerve cells and hence part of the nervous system<\/li><\/ol>\n\n\n\n
