Which features are typical for epithelium/epithelial cells?:

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

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

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

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:

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
