Which of the following is not a feature of cardiac muscles?
(1) Muscles of heart
(2) Muscles assemble in a unbranched pattern
(3) Striated
(4) Involuntary
Which of the following is not a feature of Visceral muscles?
(1) Located in visceral organs of the body like the alimentary canal
(2) No striations and smooth in appearance

(4) Transportation of food through Digested tract and maintenance of body postures are Main functions of it.
Intercalated discs are characteristic of muscles found in
(1) heart
(2) thigh
(3) urinary bladder
(4) stomach
Which of the following is a true statement about
cardiac muscle cells?
1. They lack an orderly arrangement of actin and
myosin filaments
2. They have less extensive sacroplasmic reticulum
and thus contract more slowly than smooth
muscle cells
3. They are connected by intercalated discs,
through which action potentials spread to all cells
in the heart
4. They have a resting potential more positive than
an action potential threshold
Smooth muscles are
(1) involuntary, fusiform, non-striated
(2) voluntary, multinucleate, cylindrical
(3) involuntary, cylindrical, striated
(4) voluntary, spindle-shaped, uninucleate
Choose the incorrect match

Which type of tissue is correctly matched with its location?
Tissue | Location | |

4. | Smooth muscle | Wall of intestine |
Intercalated discs are associated with what type of tissues/muscles?
1. dense regular connective tissue
2. dense irregular connective tissue
3. cardiac muscle
4. skeletal muscle
Smooth muscles occur on
