MUSCLE TISSUE
  • Muscular tissue is responsible for movement of various parts of the body .
  • Comprises of elongated cells called fibres.
Are of 3 types : 
a) Skeletal 
b) Smooth
c) Cardiac

CARDIAC MUSCLE
  • Are small and  cylindrical compared to skeletal muscles.
  • Nuclei - Central , Singular & Oval ( non multinucleated )
  • Intercalated disc between muscular fibre junctions.
   INTERCALATED DISC :  
   Intercalated disc is of 3 cell junctions :
  1. Desmosomes
  2. Gap junctions
  3. Tight junctions.     
💥THE PRESENCE OF INTERCALATED DISC MAKES CARDIAC MUSCLE A "FUNCTIONAL SYNCYTIUM "

  •  Cardiac muscles are also striated but striations are not visible in low magnification.
