Question

connective tissues explain it briefly​

Answer 1

Answer:

Hello❤

•Connective tissue is one of the four basic types of animal tissue, along with epithelialtissue, muscle tissue, and nervous tissue.

• It develops from the mesoderm. 

•Connective tissueis found in between other tissues everywhere in the body, including the nervous system.

TYPES:

■The two types of cells found in connective tissue include fibrocytes and fat cells, which are fixed cells.

■ Additionally, the extracellular substance separating the cells is made up of three types of fibers, including collagen fibers, reticular fibers and elastic fibers.

Answer 2

Answer :

Connective Tissues -

• They are widely distributed in the body.
• They include cartilage, bone, adipose and blood.
• The connective tissues except the blood secrete fibres of proteins called elastin or collagen.
• These fibres help in providing strength, elasticity and flexibility to the tissue.
• These cells also secrete polysaccharides.
• The polysaccharides are accumulated between cells and fibres and acts as matrix.
• They are classified as :

1. Loose connective tissue
2. Dense connective tissue
3. Specialized connective tissue

• The loose connective tissue are composed of cells and fibres which are loosely arranged in semi fluid ground substance.
• One example of loose connective tissue is areolar tissue.
• The areolar tissue is present beneath the skin and acts as the support framework for epithelium cells.
• The areolar tissue contains fibroblast, microphages and mast cells.
• The other example of loose connective tissue is adipose tissue.
• The adipose tissue is located beneath the skin and it helps in storing fat. The excess nutrients which are not to be used immediately are converted into fats and stored in this tissue.
• The dense connective tissues can be classified as dense regular and dense irregular tissues according to the regularity and irregularity pattern of the fibres.
• The examples of dense connective tissues can be collagen fibres which are present in rows between parallel bundles of fibres.
• The other examples of dense connective tissue can be tendons which are attached to skeletal muscles, ligaments and bones.
• Blood, cartilage and bones are types of specialised connective tissues.
• The cartilage is made up of solid and pliable material which resist compression.
• The cells of this tissue called the chrondocytes are enclosed in small cavities within matrix.
• It is present at the nose tip, outer ear joints, etc.
• Bones have a hard and non pliable ground substance.
• It is rich in calcium salt and collagen fibres which gives strength to the bones.
• It helps in the support and protection of soft tissues and organs.
• The bone cells are called the osteocytes.
• They are attached to skeletal muscles for movements.
• The bone marrow is the site of production of blood cells.
• Blood is another specialised tissue. It is a fluid connective tissue.
• It contains plasma, red blood cells and white blood cells along with platelets.
• It is the main circulating fluid which helps in the transportation of substances.
