What is PCell in biology?
The smallest unit of living structure capable of independent existence, composed of a membrane-enclosed mass of protoplasm and containing a nucleus or nucleoid.
What are P and M cells?
M and P cells also differ in ways that are not so obviously related to their morphology. M cells respond transiently to the presentation of visual stimuli, while P cells respond in a sustained fashion. Moreover, P ganglion cells can transmit information about color, whereas M cells cannot.
What type of cell is cell p?
Parvocellular cells
Parvocellular cells, also called P-cells, are neurons located within the parvocellular layers of the lateral geniculate nucleus (LGN) of the thalamus. “Parvus” is Latin for “small”, and the name “parvocellular” refers to the small size of the cell compared to the larger magnocellular cells.
What are p type ganglion cells?
P-type. P-type retinal ganglion cells project to the parvocellular layers of the lateral geniculate nucleus. These cells are known as midget retinal ganglion cells, based on the small sizes of their dendritic trees and cell bodies. About 80% of all retinal ganglion cells are midget cells in the parvocellular pathway.
Where are M and P cells?
Magnocellular cells, also called M-cells, are neurons located within the Adina magnocellular layer of the lateral geniculate nucleus of the thalamus. The cells are part of the visual system….

What is liquid liquid phase separation?
Liquid–liquid phase separation (LLPS) is a thermodynamically-driven, reversible phenomenon consisting in de-mixing into two distinct liquid phases, with different solute concentrations.
What do M cells do?
M cells are specialized epithelial cells of the mucosa-associated lymphoid tissues. A characteristic of M cells is that they transport antigens from the lumen to cells of the immune system, thereby initiating an immune response or tolerance.
What is ganglion cell?
Ganglion cells are the projection neurons of the vertebrate retina, conveying information from other retinal neurons to the rest of the brain. Their perikarya are the largest of any retinal neurons and are located along the inner margin of the retina, in the ganglion cell layer.
What is the smallest cell?
mycoplasma
Bacteria mycoplasma has the smallest cell. Its size is around 0.1 micrometers.
