{Cytokinesis: - is a cell movemet mediated by cillia + is final stage of mitotic divison - is an amoeboid movement of cells - is a kind of cell death
 * type=""}

{Lipofuscin: - is mainly inside cells with high growth-rate - is an extracellular crystalic material + is an intracellular waste product - is used for production of mucus
 * type=""}

{Mucus (mucinous) cells: - have round nucleus with prominent nucleolus + their product is PAS positive - are also inside pancreas - produce mainly enzymes
 * type=""}

{Basal annealing: - its main function is thigt anchoring to the basal membrane - is common in all epithelial cells + contains numerous mitochondria - contains numerous ribosomes
 * type=""}

{Brush border: - main supportive structure are intermediate filaments - is composed of crists (see anatomy ;-) and undulations + takes place on apical pole of some epithelial cells - is composed of cillia
 * type=""}

{Desmosome: + is responsible for mechanical cohesivity - is not associated with the cytoskeleton - anchors the cell to the basal membrane - is a long belt-like structure
 * type=""}

{Kinocilia (cilia): + they are on cells of pseudostratified epithelium of respiratory passages - their supportive structure are intermediate filaments - one cell can have only one cillium - are immotile
 * type=""}

{Which cell adhesion does not take place in the intercalated disc? + zonula occludens - fascia adherens - gap junction - desmosome
 * type=""}

{Heparinocytes: - are fixed cells of connective tissue - usually have two or three nuclei + produce heparine and histamine - produce antibodies
 * type=""}

{Fibrocartillage: + fibrillar component of its ECM contains type I collagen - is main cartillage of articular cartillages - has pronounced perichondrium - is highly vaskularized
 * type=""}

{Elastic fibers: - are clearly visible in slides stained with basic techniques + can be stained with aldehyde fuchsin - can be stained with alcian blue - are PAS positive
 * type=""}

{Osteoclast: - its nucleus has wheel-like arranged chromatin + is a multinucleated cell - is activated osteocyte - produces osteoid
 * type=""}

{Secondary bone is: - woven - spongy - compact + lamellar
 * type=""}

{White adipose tissue: - adipocytes have usually short life-span - its main function is heating + adipocytes are unilocular - is avascular
 * type=""}

{Glycoproteins: - contain usually glycogen - contain usually hyaluronic acid + contain usually oligosaccharides - contain usually glycosaminoglycans
 * type=""}

{Which protein is main protein of reticular fibers? - collagen I - collagen II + collagen III - collagen IV
 * type=""}

{Loose connective tissue is main material of: + subepithelial layer of mucosa - organ capsulla - dermis - tendon
 * type=""}

{Myofibrils: - are inside smooth muscle cells + are composed of sarcomeres - are type of cytoskeleton - contain calmodulin
 * type=""}

{Tropomyosin: - increases mechanical stiffness of the muscle - is storage of energy in the mucle fibre + prevents binding of myosin to actin - binds calcium
 * type=""}

{Glial cells: + protoplasmic astrocytes have wide processes - fibrillary astrocytes are mainly in gray matter - oligodendrocytes do not have processes - myelin is produced by mikroglia
 * type=""}

{Neurons: + action potential begins in initial segment (hilus) of the axon - GFAP is an immunohistochemical marker of neurons - neurons have no more than one dendrite - neurons are mitoticaly active
 * type=""}

{Which type of epithelium is most probably on the schema?

- stratified squamous with keratinization + pseudostratified columnar - simple columnar - none of above mentioned
 * type=""}

{Eosinophils: - their percentage in the blood (inside vessels) is about 40-60 % + specific granules contain main basic protein (MBP) - contain metachromatic granules - have small round nucleus
 * type=""}

{What is not true for monocytes? - they are the biggest blood (inside vessels) cells + they are main players of humoral immunity - they contain azurophilic granules - they give rise macrophages
 * type=""}

{Red bone marrow: - medullary period of hematopoiesis starts after the birth - takes place inside cavities of some long bones only + its stroma contains reticular connective tissue - contains plenty of adipocytes
 * type=""}

{ Retikulocyte: - is not in the peripheral blood - has long branching processes - its cytoplasm is basophilic + has no nucleus
 * type=""}
