Question

Write a before note in White fibrous connective tissue.

Answer 1

Answer:

In contrast to epithelia, connective tissue is sparsely populated by cells and contains an extensive extracellular matrix consisting of protein fibers, glycoproteins, and proteoglycans. The function of this type of tissue is to provide structural and mechanical support for other tissues, and to mediate the exchange of nutrients and waste between the circulation and other tissues. These tissues have two principal components, an extracellular matrix and a variety of support cells. These two components will be the focus of this lab.

Most frequently, the different types of connective tissues are specified by their content of three distinguishing types of extracellular fibers: collagenous fibers, elastic fibers, and reticular fibers.

Answer 2

White Fibrous Tissue:-

• It's a type of dense fibrous tissue

• Fibres and fibroblast cells are compactly packed.

• This type of tissue has bundle of collagen fibres.

• Yellow and reticular fibres are absent.

• Fibroblast and mast cells are present.

On the basis of arrangements of fibres and matrix, this tissue occurs in two forms :-

━━━━━━━━━━━━━━━

Cord:-

• Parallel bundles of collagen fibres and rows of fibroblasts are present alternatively.

• The Arrangement in this tissue has a regular pattern.

Ex:- Tendon.

━━━━━━━━━━━━━━━

Sheath :-

• The Arrangement in this tissue is irregular.

• Cells and fibres are arranged in criss-cross pattern.

Example:- Cornea of Eye.

• Periosteum (Outer cover of bone)

• Perichindrium (Outer cover of cartiladge)

• Epimysin (Cover of mussel)

• Renal capsule
