The document discusses the three major types of muscle tissues: cardiac, smooth, and skeletal. Cardiac muscle is located in the heart walls, appears striated, and is involuntarily controlled. Smooth muscle is located in organ walls except the heart, appears spindle-shaped, and is involuntarily controlled. Skeletal muscle is attached to bones, appears striated, and is voluntarily controlled. Maintaining muscle mass provides metabolic benefits like storing glucose and boosting energy, and also preserves bone density.

2. Major Types Of Muscle Tissues

3. The three major types of Muscle Tissue are:-
1. Cardiac
2. Smooth
3. Skeletal

4. Cardiac Muscle
Cardiac muscle cells are
located in the walls of
heart
Appear striated
Are under involuntary
control

5. Smooth Muscle
1. Smooth muscle fibers are
located in walls of hollow
visceral organs
2. except the heart, as heart
is neither hollow nor
visceral.
3. appear spindle-shaped.
4. Smooth muscles are
under involuntary control.

6. Skeletal Muscle
• Skeletal muscle fibers
occur in muscles
• They are attached to the
skeleton.
• They are striated in
appearance and are under
voluntary control.

7. Conclusion
1. One of the most important functions of muscles in metabolic health is
their ability to store glucose (carbohydrates) as glycogen.
2. They then use this stored glycogen as fuel and help us to boost our
energy level.
3. Moving on from the metabolic advantages of having a healthy
amount of muscle mass, strong muscles also help to preserve and
maintain healthy bone density which is very important for preventing
osteoporosis.
