The animal cells are grouped together to form animal tissues.
The animal cells are grouped together to form animal tissues. These tissues vary in their structure, function, and origin.The animal tissues are divided into epithelial, connective, muscular and nervous tissues. Let us have a glimpse of each type of animal tissue in detail.
The different types of animal tissues include:
Epithelial tissues form the protective covering and inner lining of the body and organs. These tissues were the first to evolve during evolution and were first formed during embryonic development . They develop from the ectoderm, mesoderm and endoderm of the embryo.
Following are the important characteristics of epithelial tissues:
The epithelial tissues can be classified as:
Connective tissues develop from the mesodermal cells of the embryo. they support and bind other tissues in the body. These are made up of three components:
The connective tissues perform the following functions:
The connective tissues are classified as follows:
The muscular tissue develops from the mesoderm of the embryo. It is classified into three types:
Muscular tissue performs the following functions:
The muscular tissue can be classified as:
Nervous tissue makes up the peripheral and the central nervous system . It develops from the ectoderm of the embryo. It possesses the ability to initiate and transmit the nerve impulse. Its main components include:

Provides support and protection to the body
It supports the body and gives it proper shape and form
It helps in blood circulation and keeps the heart pumping
These help in peristalsis and other involuntary functions of the body.
Provide support, help in movement and maintain homeostasis
