histo 2 Flashcards
function of free ribosome
using protein inside the cell
Attached ribosome
using protein outside the cell
The structure shape of the filaments
thread like structure
Functions of the intermediate filaments
maintaining the shape of the cell
Used as cell type specific marker
Identification of tumor
Types of filaments in the intermediate
nerves:neurofialments
Muscle:desmin
Epithelial :cytokeratin
Types of microfilaments
thin
Thick
Intermediate
The structure shape of the microtubules
pipe like structure with fixed diameter and non fixed length
Microtubules are broken into:
tubulin
Functions of microtubules
act as guiding tracts for the organelles.
Mitotic spindle formation
Cytoskeleton structure for the cell shape
Main structure component of cilia, flagella and centriole
Where we find the centriole
in the juxtanuclear position
Functions of centriole
Impo in cell division
Undivided cells, serves as a center which all organelles are polarized
Ciliated cells, act as basal bodies of the cilia
The structure shape of the cilia
hair like processes
Formation of the cilia
Shaft = contains 20 microtubules in 9 peripheral doublets and 2 single center microtubule
Basal body= consist of centriole
The movement of the flagella
while like swimming movement
Cell inclusions are
stored food
Pigments
Crystals
