3) Cardiac muscle cells are striated.

4) The skeletal striated muscle is non-voluntary muscle.

5) The endomysium wraps muscle fascicles.

6) Skeletal striated muscle cells are very long and non-branched cells.

7) A cardiac muscle cell may contain many nuclei.

8) The motor unit is made up of all muscle cells innervated by the same axon.

9) The myocardium is a muscle made up of striated muscle cells.

10) Cardiac muscle cells are branched cells.

11) Intercalary discs are dense structures that connect adjoining smooth muscle cells.

12) The heart is innervated by the autonomous nervous system.

13) There is striated muscle in the intestine walls.

14) Smooth muscle cells are much shorter than skeletal muscle cells.

15) A smooth muscle cell may contain more than one nucleus.

16) A unit of smooth muscle cells is made up of a group of cells communicated by gap junctions.

17) Cardiac muscle cells have a nucleus in the central region of the cell.

18) All skeletal muscle cells are part of muscles connected to bones by tendons.

19) All muscle cells can get contracted by means of actin and myosin filaments.

20) There are fast and slow contraction muscle cells in the smooth muscle.
