Animal tissues are groups of specialized cells that work together to perform specific functions within an organism's body. These tissues are the building blocks of organs, and organs in turn work together to form complex systems that allow an organism to carry out various functions necessary for survival. Animal tissues vary in their structure, function, and origin, and they are categorized into four main types: epithelial, connective, muscle, and nervous tissues.
These tissues are further classified into various subtypes.
Epithelial tissue plays a critical role in covering and protecting various parts of the body and its organs.
Epithelial cells, the building blocks of epithelial tissue, exhibit various types based on their shape, arrangement, and specialized functions.
Based on Shapes
Based on their Arrangements
Based on their Types
Based on Specialised Functions
Connective tissue is one of the four primary types of animal tissues, along with epithelial, muscular, and nervous tissues. It serves a crucial role in the body by providing support, connecting different structures, and performing various other functions. Connective tissues are diverse in terms of structure, composition, and function, but they all share a common characteristic of having a non-living extracellular matrix that supports and surrounds the living cells within the tissue.

Muscular tissue is a specialized type of tissue in our bodies responsible for generating movement, maintaining posture, and producing heat. It consists of elongated cells called muscle fibres or myocytes. These muscle fibres contain unique proteins that allow them to contract and relax, leading to movement.
There are three main types of muscular tissue:
Nervous tissue is a specialized type of tissue that plays a fundamental role in communication and coordination within the body. It's primarily composed of cells called neurons, which are capable of receiving, transmitting, and processing signals, also known as nerve impulses or electrical signals.
