Block 1 W3 Flashcards
Proteoglycan
Glycoprotein found in the extracellular matrix which fills the spaces between cells
Tonicity
Ability of a solution surrounding a cell to cause it to gain or lose water. It is a measure of solutes
Sinusoid capillaries
Found in the liver, bone marrow and spleen
Marker of inflammation
C-reactive protein
Cause of oedema
Inflammation, venous or lymph obstruction and lack of proteins
Morula
Mass of indistinguishibale blastomeres which are still totipotent at this stage
Which stage of the embryo does protein synthesis and ATP production begin?
Blastocyt
What is the proportion of intracellular fluid in the body?
2/3
Sessile, amoebae, ciliates and flagellates
Types of protozoa
Virus in a capsid
Enveloped virus which has a capsid from the host cell
Virus without capsid
Complex virus
Which vessels generate blood pressure?
Large elastic arteries that expand and recoil
Which vessels maintain vascular pressure?
Arterioles which change shape when transmitting blood to the capillaries
Dense-> least dense blood component
Erythrocyte -> buffy coat (containing WBC and platelets) -> plasma
Causes of low plasma protein
Low protein diet, kidney/liver disease
Constantly open channel proteins
Aquaporins, which allow the free transport of water
Apical surface
Area on epithelia where it is in contact with the lumen
Heterophilic
Adhesion that requires different molecules to bind
Gram positive bacteria
Have a lipoglycan cell wall and a layer of peptidoglycan
Proteogylcan
Mesh made of gylcoproteins, where collagen and elastin are held and bind to cells via receptors
Basal lamina
Thin membrane between epithelial cells and connective tissue consisting of collagen and glycoprotein lamina which is on the apical surface and binds to integrins
Stratified cuboidal epithelia
For secretion of sweat glands and salivary glands and protection
Basolateral surface
Epithelial surface joined to the basement membrane
Catenins
Link cadherin intracellularly to the actin cytoskeleton
Brush border
Apical epithelial surface with microvilli
