fibro-, fibr-, fiber- +

A tumor composed of mucus and fibrous elements.

Mucus coming from a rare malignant tumor found most often in the fat surrounding the kidneys or in the central part of the chest.

Plant and animal fibers.

Plant fibers include cotton, flax, hemp, jute, etc.

Animal fibers include wool, camel hair, angora, silk, etc.

Natural fibers have been used by humans for thousands of years; as, animal hair and plant fibers were spun into yarn and woven into textiles and the modern textile industry is still based on those ancient technologies.

Both natural and synthetic fibers consist of linear polymers. These polymers are converted into fibrous form by growth (animal hair and plant fibers) or extrusion (spider and silk worm) and are specifically oriented to the fiber axis.

1. A delicate fibril found in the cell body and processes of a neuron.
2. One of the delicate threads running in every direction through the cytoplasm of a nerve cell, extending into the axon and dendrites (receptive surfaces of a neuron).

Fibrosis (formation of fibrous tissue) of bone, mainly involving red bone marrow.

Fibrous thickening of the walls of the veins; called also phlebofibrosis, proliferative endophlebitis, venofibrosis, venosclerosis, and venous sclerosis.

1. Fibrosis associated with deposits of iron.
2. Fibrosis associated with small foci (origin or center of a disseminated disease) in which iron is deposited.

Natural fibers which can be spun into yarn.

One of a system of fibers found in the cytoplasm of epithelial cells (cells that cover the surface of the body and line its cavities).

1. A thin fibril made up of tonofilaments.
2. One of a system of fibers found in the cytoplasm of epithelial cells.
3. A bundle of fine filaments (tonofilaments) in certain cells, especially epithelial cells, the individual strands of which transverse the cytoplasm in all directions and extend into the cell processes to converge and insert on the desmosomes; they are thought to have a supportive or cytoskeletal function and, in keratinizing epithelia, to be the principal precursor of cytokeratin.

Fibrous hardening of the walls of the veins.

A generalized disorder of infants, children and young adults, in which there is widespread dysfunction of the exocrine glands, characterized by signs of chronic pulmonary disease (due to excess mucus production in the respiratory tract), pancreatic deficiency, abnormally high levels of electrolytes in the sweat, and occasionally by biliary cirrhosis (a rare form of liver disease which results in the irreversible destruction of the liver and bile ducts).

A rare tumor that affects human ovaries.
