microvillus

The microvillus greatly increase the amount of surface area for a cell.

Each microvillus has a dense bundle of cross-linked actin filaments, which serves as its structural core.

In the enterocyte microvillus, the structural core is attached to the plasma membrane along its length by lateral arms made of myosin 1a and Ca binding protein calmodulin.

Only those who bother to decipher the titles - the briefest of which is "Untitled (New Human Immunodeficiency Virus Bursting From a Microvillus)" -will know a trick is being played, and even so, these are objects that all too easily can be enjoyed merely for their appearance.

The plus ends of the actin filaments are located at the tip of the microvillus and are capped, possibly by capZ proteins, while the minus ends are anchored in the terminal web composed of a complicated set of proteins including spectrin and myosin II.

Many types of specialized plasma membranes can separate cell from external environment: apical, basolateral, presynaptic and postsynaptic ones, membranes of flagella, cilia, microvillus, filopodia and lamellipodia, the sarcolemma of muscle cells, as well as specialized myelin and dendritic spine membranes of neurons.

Congenital Familial Protracted Diarrhea Congenital Microvillus Atrophy Davidson's Disease Familial Enteropathy, Microvillus None Microvillus inclusion disease is an extremely rare inherited intestinal disorder (enteropathy) that is typically apparent within hours or days after birth.

Microvillus inclusion disease, also known as Davidson's disease, congenital microvillus atrophy and, less specifically, microvillus atrophy (note: microvillus is often misspelled as microvillous), is a rare genetic disorder of the small intestine that is inherited in an autosomal recessive pattern.
