Animal Tissue
Epithelial Tissue
Muscle Tissue
Connective Tissue
Nervous Tissue
Thin, protective continuous sheet of cells. Flat, cuboidal or columnar in shape and fit tightly together
Covers the space of the body and various body cavities & internal organs & blood vessels
Protection,absorbtion,sensory perception and secretion
Squamous epithelium
Cuboidal epithelium
Columnar epithelium
Vertically arranged cylindrical or brick-like cells & tall
inner lining of stomach & intestines
Some parts of kidney tubules & glandular ducts
Thin, flat with prominent nuclei closely packed
Lining the mouth and nasal cavities, blood vessels and lymph vessels
Protects the underlying parts from mechanical injury, germs, harmful chemicals and drying up
Stratified epithelium
Found in the skin and the cornea
Composed of several layers of epithelial cells
Ciliated columnar epithelial
Glandular epithelium
contains large cells & is folded inward to form a compact, hollow or tubular glands
Secretes chemical substances
lining of the stomach & intestine
lining of the trachea
Have thread-like protoplasmic projections called cilia at their free ends
Binds one tissue with another & connects various organs
Abundance of intercellular space
Fewer cellular elements & fibres
Connective tissue proper
Supportive connective tissue
Fluid connective tissue
Serves for packing & binding the organs
Areolar (packing) tissue
Adipose (fat) tissue
Fibrous connective tissue
Made of elongated cells which are strong and bundled together by the tissue; it forms a tendon which connects muscle to bone
They connect bone to bone, muscle to bone and ligaments and hold them in position
Widely spread
Makes the skin elastic which helps it to withstand pulling strain
Beneath the epidermis of skin
Specialized cells
Store Fat
Forms padding under the skin and around kidneys etc.
Cartilage
Bone
Hard porous tissue & consists of both living cells & rigid mass of inorganic salts
Good supply of blood vessels & nerves
Non porous tissue & thickened intercellular substance and has no blood vessels/nerves & semi-transplant and elastic
Found in tip of the nose, external ears, trachea and bronchial tubes, between vertebrae & at the ends of long bones
Blood
Lymph
Made of Liquid part-plasma & Cellular part - red blood cells, white blood cells & platelets
Contains white blood cells
fluid surrounding the body cells
Comes out of blood vessels
forms the muscles of the body & can contract and relax
Help the body in its movements
Striated
Unstraited
Heart/Cardiac
skeletal, striped or voluntary muscles
Made of long fibres which are nucleated & striated - light and dark bands run across the fibres
Found in arms, legs, face, neck
Constitute about 50% of the body weight
smooth,unstripped or involuntary
Made up of spindle-shaped tapering cells which have one nucleus
Found in the walls of intestine, muscles of the urinary bladder etc.
Involuntary
Help in the passage of food
found in the walls of the heart
Striated, uninucleated, relatively short & branched
Contract without outside stimulation and dont get tired soon
constitutes the nervous system
made up of elongated cells called neurons
consists of a cell body called Cyton
Contains the nucleus & elongated hair like extensions called dendrites
Axons
Very long (1m - 3m)
Form a nerve
Perception & responses of animals
