Intermediate Filaments – Definition, Structure, Function
Learn how intermediate filaments are built, why they are non-polar, where keratins, vimentin, neurofilaments and lamins occur, and how they support cell and tissue strength.
Microbiology Notes
Microfilaments: Definition, Structure, Functions & Formation
Microfilaments are thin actin filaments of the cytoskeleton. Explore their structure, polarity, dynamics, functions, locations and differences from other cytoskeletal filaments.
Mitochondria: Structure, Functions, DNA, Dynamics and Biological Significance
Learn what mitochondria are, how their membranes and cristae support ATP production, and how mtDNA, dynamics and other functions contribute to cell biology.
Microbodies: Definition, Structure, Types and Functions
Microbodies are small, single-membrane organelles found in eukaryotic cells that compartmentalize specialized metabolic reactions. The term is most closely associated with peroxisomes and specialized peroxisomal forms such as glyoxysomes, glycosomes, and Woronin bodies. Depending on the organism and cell type, these organelles participate in fatty-acid metabolism, hydrogen peroxide handling, photorespiration, the glyoxylate pathway, compartmentalized glycolysis, … Read more
Mesenchymal Stromal Cells (MSCs): Definition, Characteristics, Sources, Functions and Uses
Learn what mesenchymal stromal cells (MSCs) are, their markers, sources, differentiation, immune functions, mechanisms, clinical uses and limitations.
Transitional Epithelium – Definition, Structure, Function and Location
The epithelium of transition is a form of stratified epithelium that comprises several layers of cells, where their shape cells changes in accordance with the function that the organ performs. The epithelium can have a varied appearance, as it appears to be circular or cubic in a relaxed state with the exception of the apical layer that appears flat when stretched. The epithelium is essentially restricted to the urinary system that’s why it’s sometimes referred to”urothelium” “urothelium”.
Prokaryotic Cells – Definition, Structure, Characteristics, Functions and Examples
Learn what prokaryotic cells are, their structure, characteristics, DNA, ribosomes, cell wall, reproduction, examples, and differences from eukaryotic cells.
Epithelial Tissue – Definition, Characteristics, Types, Functions and Examples
Learn epithelial tissue definition, characteristics, structure, classification, types, functions, locations, examples, glandular epithelium and histology.
Vesicles – Definition, Structure, Types, Functions and Transport
Vesicles are membrane-bound compartments that transport, store and release cellular materials. Learn their structure, types, functions, formation and vesicular transport.
Secretory Vesicles – Definition, Structure, Formation, Types, Functions and Examples
may contain materials that must be eliminated from the cell. These materials could be harmful to cells, such as end products of chemical reactions or waste products.
