The primary molecule that makes up muscles is called myosin. Myosin is a protein that is responsible for muscle contraction by interacting with another protein called actin. This interaction allows muscles to generate force and movement.
The driving force that facilitates movement is the muscular system. Muscles work by contracting and relaxing to create movement in the body. The brain sends signals to the muscles through the nervous system to initiate and control movement.
The protein that carries oxygen to muscles is called hemoglobin. Hemoglobin is found in red blood cells and binds to oxygen in the lungs, then transports it to tissues and muscles throughout the body.
Core strength refers to the muscles in the abdomen, back, and pelvis that work in coordination to support the spine and provide stability for everyday movements and activities. Strengthening these muscles can help improve posture, reduce the risk of injuries, and enhance overall physical performance. Core exercises like planks, crunches, and bridges are commonly used to target and develop core strength.
The disuse of muscles over a long period of time is called muscle atrophy. This condition can occur as a result of immobility, injury, or certain medical conditions, leading to a decrease in muscle size, strength, and function. It is important to engage in regular physical activity and strength training to prevent muscle atrophy.
Circular Muscles are found at the openings of the body
Circular muscles help in extension and narrowing of the body of the earthworm. When circular muscles contract the protractor muscles relax causing the retractor muscles to contract, thus withdrawing the setae.

The two facial muscles that are circular are the Orbicularis Oculi(around eye), and the Orbicularis Oris(around mouth).
