Is fiber found in connective tissue?
Chapter 3 – Connective Tissue. Connective tissue provides support, binds together, and protects tissues and organs of the body. Connective tissue consists of three main components: cells, protein fibers, and an amorphous ground substance. Together the fibers and ground substance make up the extracellular matrix.
What 3 fibers does connective tissue contain?
This is a loose connective tissue widely spread throughout the body. It contains all three types of fibers (collagen, elastin, and reticular) with much ground substance and fibroblasts.
Which of the following is not a type of connective tissue?
Which of the following is not an example of connective tissue? Explanation: Skin is composed of epithelial cells, and is therefore not an example of connective tissue. The major types of connective tissue include bone, adipose, blood, and cartilage.
What type of fibers and cells are found in connective tissue?
Fibroblasts are the most common cell type of connective tissue. They produce both fibers and amorphous ground substance.
What are the two main types of Fibres of connective tissue?
There are two main types of fibre; collagen, and elastin and fibronectin. You may also come across Fibronectin which is a non-collagenous fibrous connective protein that helps cells to stick to the extracellular matrix.
What are the two basic elements of connective tissue?
All connective tissue consists of three main components: fibers (elastic and collagen fibers), ground substance and cells. Not all authorities include blood or lymph as connective tissue because they lack the fiber component. All are immersed in the body water.
Is lymph a connective tissue?
Blood and lymph are fluid connective tissues. Cells circulate in a liquid extracellular matrix.
What kind of fibers are found in connective tissues?
When a connective tissue has a high concentration of cells or fibers, it has proportionally a less dense matrix. The organic portion or protein fibers found in connective tissues are either collagen, elastic, or reticular fibers.
What kind of cells are in loose connective tissue?
Loose connective tissue is also called the areolar connective tissue. It has almost equal amounts of cells, fibers and ground substance. Chief cells are the fibroblasts.
Which is the most abundant protein in connective tissue?
Collagen fibers and reticular fibers both belong to the collagen family, of which there are over 20 different types. Collagen fibers are predominantly made of collagen type I. These are the most abundant protein fiber type, providing varying degrees of strength and rigidity to tissues.
What kind of connective tissue is produced by fibroblasts?
Reticular connective tissue is produced by modified fibroblasts called reticular cells. These produce reticular fibers arranged in an interlaced network (reticulum), similar to dense irregular connective tissue.
