ANIMAL TISSUE

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.

CONNECTIVE TISSUEConnective 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.

Connective tissue

Muscle tissueMuscle 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.

Muscle cells

Nervous tissueCells 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.

Nervous tissue

Epithelial tissueThe 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.

FunctionsProtection,secretion and absorption.
