What does reticular mean in biology?
What does reticular mean in biology?
noun, plural: reticular fibers. A type of connective tissue fiber that is made up of type III collagen secreted by reticular cells, and is characterized by an intricate interstitial network with other similar fibers to serve as a supporting mesh in soft tissues such as liver and bone marrow.
What is the role of reticular fibers?
Reticular fibers, reticular fibres or reticulin is a type of fiber in connective tissue composed of type III collagen secreted by reticular cells. This network acts as a supporting mesh in soft tissues such as liver, bone marrow, and the tissues and organs of the lymphatic system.
Where is reticular tissue in a lymph node?
In lymph nodes, they are located in the cortical and medullary zones. Their morphology is highly variable, ranging from elongated to fusiform or stellate. Reticular cells contain an internal tubular system that communicates with the extracellular matrix via orifices.
What type of tissue is reticular?
Reticular connective tissue is a type of connective tissue with a network of reticular fibers, made of type III collagen (reticulum = net or network). Reticular fibers are not unique to reticular connective tissue, but only in this type they are dominant.
What does reticular mean in anatomy?
The reticular (from the Latin reticulum, meaning net) formation is a far-reaching network of neurons extending from the spinal cord to the thalamus, with connections to the medulla oblongata, midbrain (mesencephalon), pons, and diencephalon.
What is a reticular in anatomy?
reticular fibre, in anatomy, fine fibrous connective tissue occurring in networks to make up the supporting tissue of many organs. The reticular fibres are composed of randomly oriented collagenous fibrils lying in an amorphous matrix substance.
What type of cells are in reticular tissue?
The cells that make the reticular fibers are fibroblasts called reticular cells. Reticular connective tissue forms a scaffolding for other cells in several organs, such as lymph nodes and bone marrow.
What kind of tissue is reticular?
loose connective tissue
Reticular tissue, a type of loose connective tissue in which reticular fibers are the most prominent fibrous component, forms the supporting framework of the lymphoid organs (lymph nodes, spleen, tonsils), bone marrow and liver.
Which is the correct definition of a reticular cell?
An undifferentiated cell of the spleen, bone marrow, or lymphatic tissue that can develop into one of several types of connective tissue cells or into a macrophage. 2. A cell of reticular connective tissue.
What makes up the stroma of a reticular cell?
cell with processes making contact with those of other similar cells to form a cellular network ensheathing a network of reticular fibers, which constitutes the stroma of all lymphoid organs except the thymus.
How are reticular cells used to treat sepsis?
While all control mice died, four of nine receiving the reticular cellssurvived. The researchers found that the reticular cellstrigger the release of nitric oxide using an enzyme called nitric oxide synthase-2. Collagen-making cells curb sepsis: experimental treatment halts mice’s immune overreaction
