This document discusses the four main types of animal tissues: connective tissue, muscle tissue, nervous tissue, and epithelial tissue. Connective tissue includes cells scattered throughout an extracellular matrix and provides structure and support. Muscle tissue contains three categories of muscle cells that produce movement. Nervous tissue forms the central and peripheral nervous systems. Epithelial tissue covers organ surfaces and forms protective barriers.

5. ANIMAL TISSUE

6. A tissue is an ensemble of similar cells from the same
origin that together carry out a specific function.
There are animal tissues and plant tissues.
Animal tissues can be grouped into 4 type.
Connective tissue.
 Muscle tissue.
 Nervous tissue.
 Epithelial tissue.

7. CONNECTIVE TISSUE
Connective tissues are fibrous tissues.
They are made up of cells separated by non-living
material, which is called an extracellular matrix.
Connective tissue gives shape to organs and holds
them in place. They support and bind other tissues.
connective tissue typically has cells scattered
throughout an extracellular matrix.
Eg:-Blood ,Bone.

9. Muscle tissue
Muscle cells form the active contractile tissue of the
body known as muscle tissue or muscular tissue.
Muscle tissue functions to produce force and cause motion,
either locomotion or movement within internal organs.
Muscle tissue is separated into three distinct categories:
 viseral or smooth muscle, which is found in the inner
linings of organ.
 Skeltal muscle , which is found attached to bone providing
for gross movement.
 Cardiac muscle which is found in the heart, allowing it to
contract and pump blood throughout an organism.
 They are the longest group of cells in the human body.

11. Nervous tissue
Cells comprising the central nervous system
and peripheral nervous system are classified as neural
tissue.
In the central nervous system, neural tissue forms the
brain and spinal cord.
In the peripheral nervous system forms the cranial
nerves and spinal nerves, inclusive of the motor
neurons.

13. Epithelial tissue
The epithelial tissues are formed by cells that cover the
organ surfaces such as the surface of the skin,
the reproductive tract, and the inner lining of the
digestive tract.
The cells comprising an epithelial layer are linked via
semi-permeable, tight junctions; hence, this tissue
provides a barrier between the external environment
and the organ it covers.
Functions
Protection,secretion and absorption.
