A cell is the basic structural and functional unit of a living organism. A tissue is a group of cells having a common origin, similar structure and function and held together by a cementing substance. Example: Connective Tissue
Animal tissues are different and are broadly classified into four types :
- Epithelial Tissue
- Connective Tissue
- Muscular Tissue and
- Neural \ Nervous Tissue
In this article we are going to discuss about Connective Tissues only.
|CHARACTERISTICS||Consists of a matrix|
and the cells are
embedded in it.
|LOCATION||Found in the deeper parts of the body in|
between the skin and
organs and keeps
them in proper
Types of Connective Tissues
- Connective tissue proper
- Supportive connective tissue
- Fluid connective tissue
Connective tissue proper:
|CHARACTERISTICS||Made up of irregular cells scattered and|
embedded in a soft
|LOCATION||Encompasses all the internal organs and|
|FUNCTION||Acts as a binding|
structure within the
Types of Connective tissue proper:
- Areolar tissue
- Adipose tissue
- Fibrous tissue
|CHARACTERISTICS||Made of gelatinous|
cells and irregularly
|LOCATION||Found between the|
skin and muscles,
around the blood vessels, nerves and in
the bone marrow.
|FUNCTION||Fills the space inside the organs and supports and|
|CHARACTERISTICS||Cells are filled with|
fat globules, situated in a large central vacuole of a cell, pushing the cytoplasm and the
nucleus to the
|LOCATION||Found beneath the|
skin, around the kidneys and other
internal organs such
|FUNCTION||Acts as an insulator|
because of the
storage of energy in
the form of fats. It
insulates the body
and prevents the
loss of heat.
|CHARACTERISTICS||Mainly formed of|
which form the tendons and ligaments.
|LOCATION||Found in the spaces|
between the bones and muscles.
|FUNCTION||1. Tendons help to|
attach muscles to
2. Ligaments serve to
hold the structures
together and keep
them strong and
Supportive connective tissue:
|CHARACTERISTICS||Has fibres as its main matrix element.|
|LOCATION||Found in bones and|
Types of Supportive connective tissue:
|CHARACTERISTICS||Non-porous, semi-transparent and|
|LOCATION||Present in the nose, external ear, trachea,|
larynx, ends of the long bones and between the vertebrae.
|FUNCTION||Smoothens the bone surface at joints, allowing smooth movement of these joints.|
|CHARACTERISTICS||1. Hard, strong and|
2. Consists of living
|LOCATION||Forms the rigid part of the skeletal system.|
|FUNCTION||1. Forms the|
supporting framework of the body.
2. Gives shape and
rigidity to the body.
Fluid connective tissue:
|CHARACTERISTICS||Consist of fluid/liquid as the ground substance.|
throughout the body.
|FUNCTION||1. Provides nutrition.|
2. Helps in transport
3. Gets rid of waste
Types of Fluid connective tissue:
|CHARACTERISTICS||1. Contains a straw-coloured fluid matrix called blood.|
2. It consists of
plasma (55%) and
cellular part (45%)
which contains cells, RBCs, WBCs and platelets.
throughout the body
body parts and
establishes continuity within the body.
|CHARACTERISTICS||1. Fluid surrounding|
the body cells.
2. Contains WBCs.
throughout the body.
|FUNCTION||1. Transportation of|
2. Provides protection
