The human muscle system, also known as the muscular system, is a complex network of muscles that allows the body to move, maintain posture, and perform various functions. Muscles are essential for both voluntary and involuntary movements, and they play a crucial role in overall body function. Here's an overview of the human muscle system:

Types of Muscles:
There are three main types of muscles in the human body:

a. Skeletal Muscles: These are the muscles that are attached to bones by tendons and are responsible for voluntary movements, such as walking, lifting, and speaking. Skeletal muscles are under conscious control.

b. Smooth Muscles: Smooth muscles are found in the walls of various internal organs, such as the digestive tract, blood vessels, and respiratory tract. They are responsible for involuntary, rhythmic contractions and are not under conscious control.

c. Cardiac Muscle: Cardiac muscle is found exclusively in the heart. It contracts rhythmically to pump blood throughout the body. Like smooth muscles, cardiac muscle is involuntary.
