  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 (...)

• 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 (...)

  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 (...)

• bronchioles
  14 November 2004

  Bronchiole Adj. bronchiolar WKP
  Definition : The bronchioles or bronchioli are the passageways by which air passes through the nose or mouth to the alveoli (air sacs) of the lungs, in which branches no longer contain cartilage or glands in their submucosa. They are branches of the bronchi, and are part of the conducting zone of the respiratory system.
  The bronchioles divide further into smaller terminal bronchioles which are still in the conducting zone and these then divide into (...)

  Immunochemistry
  Exocrine acinar cells and endocrine islet cells are well-differentiated cells which express the keratin combination 8 and 18, whereas the less-differentiated cells of the ductal tree are characterized by the additional expression of keratin (...)
