Types of Tissue - Connective , Epithelial, Muscle and Nervous Tissue

Tissues in the Human Body

 

Tissue is a group of cells made up of cells that have a similar shape, structure, and function. Each type of tissue is differing from the each other in structure and function. Different types of tissues can be found in different body organs. 

The organs in the human body are composed of four major types of tissues-

 

1. Epithelial tissue

2. Connective tissue

3. Muscle tissue, and 

4. Nervous tissue

 

The tissue of bodywork together for different purposes. The human body organs are sheets of cells that are made up of many tissues, connected together, and work together for different purposes to execute actions inside the body.

 

Types of Tissue in the Human Body

There are four types of tissue in body-

 

1. Epithelial Tissue

 

Epithelial tissue or epithelium tissue forms sheets of cells that cover surfaces of the body, line internal cavities, hollow organs, and passageways, and forms ducts and certain glands.

 

Check out here classification of epithelial tissue. The origin of epithelial tissues from the ectoderm, mesoderm, and endoderm of the embryo.

 

 

Functions of Epithelial Tissue

 

The major function of epithelial tissues are-

 

1. It covers body surfaces

2. It lines hollow organs, body activities, and ducts

3. It forms ducts and certain glands

 

 

2. Connective Tissue

 

 

Connective tissue is a group of tissues that connect other tissues together to give structure to other tissues and organs in the body. It provides support and protects the organs in the body.

 

Know here the classification of connective tissue. The embryonic origin of connective tissue is developed from Mesoderm.

 

 

Functions of Connective Tissue

 

The major function of connective tissue are-

 

1. Binding and supporting

2. Binding them together

3. Support, protect the organ

4. Shock absorption

5. Strong reserve energy

6. Transporting substances within the body

7. Allow for free movement of body parts

8. Storing fat

 

3. Muscle Tissue

 

Muscular tissue is made up of muscle cells, it is specialized cells that have the ability to contract and expand and have tensile strength.

Muscular tissue produces the forces, responsible for the movement of the body parts such as the arm, legs, heart, stomach, and other parts of the body.

 

Check out here the classification of muscle tissue. Muscle tissue develops from Mesoderm.

 

Functions of Muscle Tissue

 

Muscle tissue involves in-

 

1. Help in contraction and relaxation

2. Responsible for movement, locomotion

3. Support for bone

4. Heat store, produce heat

5. Provide protection

 

 

4. Nervous Tissue

 

Nervous tissue is specialized tissue found in the central nervous system (CNS) and peripheral nervous system (PNS); brain and spinal cord and nerves.

Nervous tissue is responsible for coordinating and controlling the body or specific parts of the body and movements and bodily function.

Nervous tissue is made up of neurons and neuroglial cells. neurons are also called nerve cells. Nervous tissue develops from Ectoderm.

 

Functions of Nervous Tissue

 

The major function of nervous tissue is-

 

1. Responsible for conducting the nerve impulses.

2. Generate nerve impulses and transmission of cellular signals

3. Responsible for sending and receiving signals from the brain

4. Neurons transmit nerve impulses to other cells

5. Process and transmit information throughout the body

6. It is responsible for communicating information in both forms; chemical and electrical.
