Draw well labelled diagrams of various types of muscles found in human body.

types of muscles in human body

Smooth Muscle Tissue

  • These are non-striated, involuntary muscles controlled by the Autonomous Nervous System.

  • It stimulates the contractility of the digestive, urinary, reproductive systems, blood vessels, and airways.

  • The actin and myosin filaments are very thin and arranged randomly, hence no striations.

  • The cells are spindle-shaped with a single nucleus.

Cardiac Muscle Tissue

  • These are found only in the heart.

  • These are involuntary muscles and the heart pumps the blood through cardiac contractions.

  • The cells of the cardiac muscles known as the cardiomyocytes are striated.

  • They are single-celled and uninucleated

Skeletal Muscle Tissue

  • These muscles are attached to the skeleton and help in its movement.

  • These muscles are also known as striated muscles because of the presence of alternate patterns of light and dark bands.

  • These light and dark bands are sarcomeres which are highly organized structures of actin, myosin, and proteins. These add to the contractility and extensibility of the muscles.
