TISSUES
Tissues are group of cells that work together to perform a particular functions.
 There are four main type of tissues. They are:
I.
Epithelial tissues
II. Connective tissues
III. Muscle tissues
IV. Nervous tissues


EPITHELIAL TISSUES


Simple epithelial tissues
This tissue has only one cell layer.



Compound epithelial tissues
This tissue has more than one cell layers.

EPITHELIAL TISSUES
Epithelial tissues cover the whole surface of the body
 It is made up of cells closely packed and range in one or more layer.
 This tissues is specialized to form the covering or lining of all internal and external body surface.
 The wpithelial have nerve supply but do not have blood supply, they get the oxygen and nutrients form form deeper tissues by diffusion.


TWO TYPES OF EPITHELIAL TISSUES
1.

2.

Simple epithelium
a) Simple squamous epithelium
b) Simple cuboidal epithelium
c) Simple columnar epithelium
Compound epithelium
a) Stratified squamous epithelium
b) Stratified cuboidal epithelium
c) Stratified columnar epithelium
d) Transitional epithelium

SIMPLE SQUAMOUS EPITHELIUM
The structure of the squamous epithelium is a single layer of flat cells.
 In the center of the cell, there is a single spherical nucleus.  Have basement membrane(basal lamina).
 They are found in Lung Alveoli and Blood Capillaries.


SIMPLE CUBOIDAL EPITHELIUM
The structure of the cuboidal epithelium is a single layer of cube-like cells.
 They have large single spherical and central nucleus.
 Have basement membrane.
 They are found in Thyroid Gland and Surface of
Ovaries.


SIMPLE COLUMNAR EPITHELIUM
The structure of the simple columnar epithelium is a unilayer of column-like cells which are taller than others.
 They have single spherical nucleus.
 Have basement membrane.
 They are found in The lining of the Digestive Track and Line the
