CITOESQUELETO Flashcards
Network of proteins within the cell
Cytoskeleton
Groos main objective of cytoskeleton
anchor organelles & structure
dynamic network so that the cell can move, divide, contract, move molecules in/out
Main componentes cytoskeleton
Actin filaments
Intermediate filaments
Microtubules
Microfilaments (Actin filaments)
2 strands
allow cell to change in muscle contraction
plays role mitosis
Miosin filaments
bound actin filaments
allow movement muscles
Diapedesis
Neutrophia uses pseudopodia to crawl in or out of blood vessels
Microtubles
thick
made out of Alpha and Beta tubular (protein)
railloads for intracell transports
plays a roll in the centrosome of cell division
Intermediate Filaments
Less dynamic, average streght
fasten organelles, anchor them, anchor them to enviroment
Type I & II intermediate
keratins
hair, nails
Type III Vimetin
smooth muscle cells
fibroblasts
white blood cells
Type III Desmin
sarcomere that makes muscles contract
Type IIIGlial Fibrary Acidic Protein
supporting cells in CNS, astrocytes
Type III Peripherin
neurons of PNS
Type IV sinemina
que proporciona resistencia a la tensión mecánica en las células,
ABUNDANT SKELETAL CELLS
tipo IV
syncoilin
Type V
alfa-internexina, y un grupo llamado simplemente neurofilamentos que proporcionan soporte estructural a los axones.
tipo v
intermedios de tipo V y VI, que se encuentran en casi todas las células: los filamentos intermedios de tipo V son las laminas, que forman la lámina nuclear alrededor del núcleo de una célula.
que ataca Amanita phalloides,
filamentos de actina del citoesqueleto.
