Answer 2

There are three types of muscle tissue: Visceral, cardiac, and skeletal.

Cardiac Muscle :

As the name suggests it found only in the heart, cardiac muscle is responsible for pumping blood throughout the body.

• Cardiac muscle tissue cannot be controlled consciously, so it is an involuntary muscle.

• The cells of cardiac muscle tissue are striated—that is, they appear to have light and dark stripes when viewed under a light microscope.

• The arrangement of protein fibers inside of the cells causes these light and dark bands. (Striations indicate that a muscle cell is very strong, unlike visceral muscles.)

Skeletal Muscle :

• Skeletal muscle is the only voluntary muscle tissue in the human body—it is controlled consciously.

• Every physical action that a person consciously performs (e.g. speaking, walking, or writing) requires skeletal muscle.

• The function of skeletal muscle is to contract to move parts of the body closer to the bone that the muscle is attached to.

• Skeletal muscle derives its name from the fact that these muscles always connect to the skeleton in at least one place.

Visceral Muscle( also known as smooth muscle ) :

• Visceral muscle is found inside of organs like the stomach,blood vessels, intestine, oesophagus etc.

• The weakest of all muscle tissues, visceral muscle makes organs contract to move substances through the organ.
