TISSUE -
A Group Cells That Have Similar Structure And That Function Together As Unit.
TYPES OF TISSUES -
a) CONNECTIVE TISSUE -
b) EPITHELIAL TISSUE -
c) MUSCLE TISSUE -
d) NERVOUS TISSUE -
a) CONNECTIVE TISSUE -
It Is Composed Primarily Of An Extracellular Matrix And Limited Number Of Cells.
There Are 7 Types Of Connective Tissues -
a) Loose Connective Tissue
b) Adipose Tissue - ( Found Under Skin ) Subcutaneous Fat
* Function - Store Excess Energy In The Form Of Fatty Molecules Mainly Triglycerides)
c) Dense Fibrous Connective Tissue
d) Elastic Connective Tissue
e) Cartilage
f) Osseous Tissue ( Bone)
g) Blood
FUNCTION OF CONNECTIVE TISSUE -
a) Connect And Support Other Tissues Of The Body.
b) Mechanical Support
c) Medium For Exchange Of Nutrients And Waste Products
d) Energy Stored And Thermal Insulation
e) Defensive Function - Barrier, Engulf Bacteria, Antibodies
B) EPITHELIAL TISSUE -
Form The Covering Of All Body Surfaces, Line Body Cavities And Hollow Organs And The Major Tissue In Glands.
FUNCTION -
> Secretion, Protection, Absorption, Transportation And Special Sensory Receptive)
C) MUSCLE TISSUE -
Composed Cells That Have The Special Ability To Shorten Or Contract In Order To Produce Movement Of The Body Parts.
FUNCTION -
> Movement, Support, Protection, Heat Generation, Blood Circulation
d) NERVOUS TISSUE -
It Is Found In Brain, Spinal Cord, And Nerves
> It Is Responsible For Coordinating And Controlling Many Body Activities.
> It Stimulates Muscle Contraction, Create An Awareness Of The Environment.
> Nervous Tissue Is Made Up Two Cell Categories -
a) Neuroglia b) Neurons
> It Can Send And Recive Electrochemical Signals Of Body.
