Which features are typical for epithelium/epithelial cells?:
Vascularization
Polarity
Great amount of extracellular matrix
Possibility to regeneration
Location in the basement membrane/basal lamina
Glands:
An example of unicellular gland is the goblet cell
Endocrine glands are ductless
In merocrine glands the secretory granules leave the cell by exocytosis
Glands develop from adipose tissue
Glands develop from connective tissue
Conective tissue proper:
It originates from mesenchyme
The surface of the plasma cell contains receptors for IgE
Tropocollagen is monomer unit compose of 3 alpha-chains
Fibroblast are active cells, fibrocytes are quiescent cells
Fibronectin is component of glycoaminoglycan
The extracellular matrix:
Is divided into ground substance and fibers
Tropocollagen is aggregated into fibers In cytoplasm of cell
Reticular fibers are composed of type 3 collagen
) Hyaluronic acid (hyaluronan) is a type of GAG
The main component of elanuin fibers is type 4 collagen
Adipose tissue – find true sentences
There are two types. White (unilocular) brown (multiocular)
There are no blood vessels in unilocular tissue
Cells of multiocular adipose tissue contain abundant brown mitochondria
Lipid droplets of adipocytes are enveloped by intermediate filaments
Mitochondria of unilocular adipocyte is thermogenin
Cartilage:
Derive from mesenchyme
Isogenous groups and territorial matrix from chondrons
The matrix of hyaline cartilage contains mainly collagen type 2
Is devoitd of glycoaminoglycans
Only fibrocartliage possesses perichondrium
Which compounds of ECM are characteristic for cartilage?
Dermatan sulfate
Hyaluronic acid
Keratin sulfate
Chondronectin
Osteocalcin
Secondary bone tissue:
is so-called mature bone tissue
Contains irregularly arrangement of collagen fibers
Of compact bone contains osteons
Have no blood vessels
Contains large amount of nerves
Proteins associated with skeletal muscle:
Myosin 2 – major protein in thin filaments
Troponin I – binds calcium ions
A-actinin anchors plus ends of thick filaments to Z disk
) tropomodulin - caps the minus end of thin filaments
Calmodulin- binds magnesium ions
Regeneration of muscle tissue:
Smooth muscle tissue – damage is replaced by connective tissue
Satelite cells are responsible for skeletal muscles ability to regenerate
Cardiac muscle has no regenerative capacity
Each type of muscle tissue has great regenerative capacity
Each type of muscle tissue has no regenerative capacity
Intermediate filaments include:
cytokeratin filaments
Actin filaments
Wimentin filaments
Myosin filaments
desmin filaments
Find correct connections regarding the epithelium:
Esophagus – stratified cuboidal
Trachea – psuedostratified columnar ciliated
Urinary bladder – stratifid cuboidal
Cornea – stratified cuboidal
Blood vessel – simple squamos
Find true sentence:
Zonula occludens are located in the most upper part of the cell
Cadherin is present within zonula adherens
Every cell in stratified epithelium is connected by basal lamina
Connexons are associated with nexuses
Occludin and claudin are proteins involved in tight junctions
Aniline blue is typical staining method for:
Elastic fibers
Nucleus
Collagen fibers
Mitochondria
Ground substance
Find correct pairs regarding histological stains and reactions:
Hematoxylin blue – blue nucleus
Eosin – blue collagen fibers
Silver stain – black collagen fibers
Iron hematoxylin – black cardiac muscle
Wright and giemsa stains – used for staining of blood cells
Find correct descriptions:
Epithelial tissue – large amount of ecm
Connective tissue – ground substance contains hyaluronic acid
Skeletal fibers and cardiac cells - sarcomers
Cartilage drives from mesenchyme
Elastic cartilage – does not contain perchondrium
Synthesis of collagen in fibroblast
Include a lot of posttransitional modifications
depends on O2….Fe2+ and ascorbic acid
Aggregation of tropocollagen into collagen fibers take place inside the cytoplasm
Nonhelical propeptides are present in collagen fibrils to protect its structure
Occurs in intracellular and extracellular enviroment
Find true answer regarding connective tissue:
Fibroblast and fibrocytes are residents cells
Leukocytes, mastocytes are wandering cells
Hyaluronic acid can bind monomers to form proteoglycans aggregates
Eticular fibers consist mainly type 1 collagen
Collagen contains unusal amino acids desmosine and isodesmosine
Desmin filaments are present in:
Skeletal muscle cells
Epithelial cells in respiratory system
Cells of epidermia
Cardiac muscle cells
Neurons of central nervous system
In core of microvilli can be found:
Intermediate filaments
Microfilaments
Microtubules
Dynein
Connexions
Mark correct statements about cardiac muscle:
Cardiac muscle are multinucleated
Has no regenerative capacity
Contains myofilaments and sarcomers
T-tubules and cisternae of SER forms TRIADS
T-tubules and cisternae of SER forms DIADS
Choose correct/true statements:
Differentiation is also named proliferation
Differentiation occurs only during prenatal life
Differentiation can occur postnataly
Monocytes are able to differentiate into macrophages
Nerve cells lost their ability to proliferation and differentiation as well
