Distinguish between (a) Simple epithelium and compound epithelium (b) Cardiac muscle and striated muscle (c) Dense regular and dense irregular connective tissues (d) Adipose and blood tissue (e) Simple gland and compound gland

             Simple epithelium

            Compound epithelium

• Formed of single layer of cells

• Formed of several layers of cells

• Seen in areas like lining of lungs,alveoli

• Seen in areas like skin,tongue

• There are four types of simple epithelium 

• Only two types of compound epithelium

• The main functions include absorption,excretion

• The main function is protection

             Striated muscle

              Cardiac muscle

• Found in regions like limbs,tongue

• Found only in heart region

• Voluntary in action

• Involuntary in action

• Multinucleated cells

• Uninucleated cells

• Long and cylindrical muscles

• Short and branched muscles

      Dense regular connective tissue

       Dense irregular connective tissue

• Parallel arrangement of collagen fibres

• Irregular arrangement of collagen fibres

• Seen in ligaments and tendons

• Seen in dermis of skin

• Collagen fibres are darkly stained

• Collagen fibres are not darkly stained

             Adipose tissue

                   Blood tissue

• Formed of collagen fibres,adipocytes

• Formed of red blood cells,white blood cells,platelets

• Helps in storage of fats

• Helps in transport of oxygen,hormones,nutrients

• Seen in below the skin

• Seen in blood vessels

           Simple gland

             Compound gland

• Cells are unicellular

• Cells are multicellular

• Absence of branched ducts

• Presence of branched ducts

• Example:Sweat gland

• Example:Pancreas
