1
Understand the three main types of muscle tissue in the human body: skeletal, cardiac, and smooth muscle.
Recognize that skeletal muscle is voluntary and is primarily associated with movement and posture, attached to bones.
Identify cardiac muscle as involuntary, found only in the heart, and responsible for pumping blood throughout the body.
Note that striated muscle refers to the appearance of both skeletal and cardiac muscles under a microscope, due to their banded appearance.
Conclude that smooth muscle is involuntary and primarily composes many internal organs, such as the intestines, blood vessels, and bladder, where it helps regulate functions like digestion and blood flow.
