Explanation:

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.

Types of Animal Tissue

The different types of animal tissues include:

Epithelial Tissue

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.

Characteristics of Epithelial Tissues

Following are the important characteristics of epithelial tissues:

These can be single-layered or multi-layered.

The tissues have the power to regenerate.

These are held together by gap junctions, tight junctions, zonula adheren, desmosomes, or interdigitation.

The plasma membrane of these cells is specialized into flagella, cilia, and microvilli.

Classification of Epithelial Tissues

The epithelial tissues can be classified as:

Function

Sensory epithelium

To perceive stimuli

Glandular epithelium

Secretes chemicals

Pigmented epithelium

Imparts colour in retina

Absorptive epithelium

For absorption
