  The spleen (from Greek σπλήν—splḗn) is an organ found in virtually all vertebrate animals. Similar in structure to a large lymph node, it acts primarily as a blood filter. Thus, life is possible after the spleen is removed.
  The spleen is the (...)

  NCK2-18: normal endomyocardial biopsy (PAS)
  NCK2-19: normal endomyocardial biopsy (PAS diastase)
  Definition: The myocardium is composed primarily of a collection of specialized muscle cells called cardiac myocytes or cardiomyocytes.
  They are arranged largely in a circumferential and spiral orientation around the left ventricle, the chamber that pumps blood to the systemic circulation.
  Cardiac myocytes have five (...)

• osteoclasts
  29 October 2003

  Definition: The osteoclast is the cell responsible for bone resorption. It is derived from hematopoietic progenitor cells that also give rise to monocytes and macrophages.
  Information regarding the molecular regulation of osteoclast formation in humans is limited. In mice, a number of transcription factors, including PU.1 and Fos, are essential for developing an osteoclast phenotype.
  The cytokines and growth factors crucial for osteoclast differentiation and maturation in humans include (...)

• corpus luteum
  17 November 2004

  corpora lutea (corpus luteum)
  Definition: Corpus luteum is 1 to 2 cm, round yellow, lobulated structure with cystic center. It has luteinized granulosa and theca cells.
  In pregnancy, coprus luteum is larger, bright yellow with prominent central cavity, hyaline droplets and calcification. Progesterone from the corpus luteum maintains the uterus for implantation.
  The corpus luteum secretes progesterone which induces a secretory endometrium. It normally regresses in 14 days unless it is (...)
