The muscle which is under our control and helps in movement is Striated muscle.
Striated muscle, also known as skeletal muscle, is the muscle type that is under our control and is responsible for voluntary movements. Here are some key points about striated muscle:
1. Structure: Striated muscle is composed of long, cylindrical fibers that are bundled together to form muscles. These fibers have a striped or striated appearance when viewed under a microscope, hence the name.
2. Control: Striated muscle is under conscious control, meaning we can consciously decide to contract or relax these muscles to produce movement. This control is achieved through the somatic nervous system.
3. Location: Striated muscle is found throughout the body and is attached to bones by tendons. It is responsible for various movements, such as walking, running, lifting weights, and facial expressions.
4. Voluntary movements: Striated muscle is responsible for voluntary movements, which are movements that we consciously initiate and control. These movements are usually deliberate and require coordination between the brain, nerves, and muscles.
5. Appearance: Under a microscope, striated muscle fibers appear striped due to the arrangement of protein filaments called actin and myosin. This organized arrangement allows for efficient muscle contraction and movement.
In conclusion, striated muscle is the type of muscle that is under our control and helps in voluntary movements. It plays a crucial role in our ability to move and perform various activities.
