Three  types of muscle tissue

Skeletal muscle

Cardiac muscle

Smooth muscle

Overview by Khan academy



Skeletal muscle Are defined by structure and function

a)     Voluntary (controlled movement)

b)    Striation due to overlapping protein.

c)     Due to overlapping muscle bundles they appear multi nucleated



Cardiac Muscle Are defined by structure and function

a)     Involuntary ( autonomic nervous)

b)    Cylindrical fibres

c)     Intercalates discs ( join cells )

What is the function of the intercalated discs?




Smooth muscle Are defined by structure and function

a)     Spindle shaped fibres

b)    Central nuclei

c)     Found in walls of internal organs or viscera.

d)    Contracts (involuntary via autonomic system.

e)    Called “smooth” due to lack of striation
