Question

Explainal dense connective tissue? What are the types of it​

Answer 1

$\huge{\boxed{\sf{Dense \: Connective \: Tissue}}}$

>> It is a type of connective tissue in which their constituents like fibres and fibroblasts cells are almost concisely stuffed or filled.

>> We can observe dense connective tissue in Tendons and Ligaments.

$\huge{\boxed{\sf{TYPES :}}}$

1. Dense Regular

• In this type, the fibres and fibroblasts cells are positioned in a regular manner or proper way.

• Example - Tendons and Ligaments.

2. Dense Irregular

• The fibres and fibroblasts cells in this type of dense tissue is aligned in an irregular manner.

• Example - Skin Tissue.

Answer 2

Dense Connective Tissue

•Dense connective tissue is also known as fibrous connective tissue due to presence of more fibres and less matrix as it's composition components.

•They show regular and irregular both patterns and therefore it is named as dense regular or dense irregular tissue.

•Dense Connective Tissue have both fibres fibroblast cells which are closely packed to each other.

Types

They are divided mainly into three parts

1. White Fibrous Connective Tissue

2. Yellow Fibrous Connective Tissue

3. Reticular Fibrous Connective Tissue

1. White Fibrous Connective Tissue

•In this types of tissue the bundles of collagen fibres are more in quantity whereas in other tissues like yellow fibres and reticular fibres are completely absent.

•The number of mast cells and fibroblast is more in it.

•Cord is one of the type of it in which collagen fibres are fixed at a regular pattern.

Example- Tendon (Connect muscle and bone structurally).

•Sheath is the second form of it in which there is no regular pattern of fibres and matrix adjustment.

Examples-

(i) Pericardium (Covering of heart)

(ii) Periosteum (Outer Covering of bone)

(iii) Renal Capsule (Around Kidney)

(iv)Tunica Albugenia (Covering of testis)

(v) Epimysium (Covering of muscle).

2. Yellow Fibrous Connective Tissue

•The name of it is due to presence of more yellow fibres in quantity comparatively collagen fibres.

•Reticular fibres are absent in it.

•Cord is form of it in which bundle of collagen fibres and matrix is distributed in a regular pattern to form yellow matrix network.

Example- Ligaments ( Connect bone to bone structurally).

•Sheath is the another form in which fibres are distributed irregularly.

Examples-

(i) Wall of lymph vessels

(ii) Wall of blood vessels

(iii) Wall of alveoli of lungs

(iv) Wall of small bronchioles

(v) True Vocal cords.

3. Reticular Fibrous Connective Tissue

•It is also known as lymphoid tissue because it is mostly found in lymphoid organs.

•The characteristic feature of its matrix is that it is exactly like lymph.

•Based on name reticular fibrous are present in more amount.

•The main function of this tissue is to provide support and strength.

•Also in it no such form like Cord and sheath because it is mostly liquid.

Examples-

(i) Spleen

(ii) Lymph nodes (Like Tonsils)

(iii) Endosteum (Covering of bone marrow cavity).
