Q8) DIFFERENTIATE BETWEEN STRIATED,  UNSTRIATED AND MUSCLE ON THE BASIS OF THEIR STRUCTURE AND SITE/ LOCATION IN THE BODY?
THE DIFFERENCE BETWEEN THESE ARE:
STRIATED MUSCLE

1. THE CELLS OF STRIATED MUSCLES ARE LONG, CYLINDRICAL UNBRANCHED AND MULTINUCLEATED.
2. STRIATED MUSCLES ARE PRESENT IN OUR LIMBS AND JOIN THE BONES.
UNSTRIATED MUSCLE
1. THE CELLS OF UNSTRIATED MUSCLE ARE LONG, POINTED AT THE ENDS AND UNNUCLEATED.
2.THESE MUSCLES ARE PRESENT IN ALIMENTARY CANAL, BLOOD VESSELS, IRIS OF THE EYE, URETER AND BRONCHI.
CARDIAC MUSCLE
1. THE CELLS OF CARDIAC MUSCLEWS  ARE CYLINDRICAL BRANCHED AND UNINUCLEATED.
2. CARDIAC MUSCLE PRESENT IN THE HEART.
