A
fibre: Lt. fibra = a fibre, adj. Lt. fibrosus = fibrous.
B
fibril: diminutive of Lt. fibra = a fibre.
Fibrin (FI-brihn) an insoluble protein in the blood, formed from
C fibrinogen & required for blood clotting.
Fibrinogen (fi-BRIHN-o-jehn) a large plasma protein, the precursor of
D
fibrin. It is converted to fibrin by thrombin.
E
Fibroblast (FI-bro-blahst) a large cell in CT that manufactures much
F
of the extracellular material.
Fibrocartilage a type of cartilage (CT), which is distinguished from
G
other cartilages by the small size and numbers of chondrocytes and
lacunae, differential staining, and close resemblance to dense regular
H
CT. It is found in the intervertebral discs particularly the outer ring.
I

CT, it contains the sclera & the cornea.

U
composed of protein filaments to provide mobility. In human cells, it is
found only in sperm cells.
V

W
flexure: Lt. flexura = a bending.
flocculus: diminutive of Lt. floccus, a tuft. resembling a picture of
