Anisotropic bands

Question 17

Type of muscle found in the heart

Answer 17

Cardiac muscle

Question 18

This type of muscle is similar, to that of the skeletal muscle because the myofibrils are also striated. but the striation is finer than the skeletal muscle

Answer 21

Intercalated disk

Question 22

Another term for cardiac muscle

Answer 22

Striated involuntary muscle
