Which muscle is consciously controlled?
Skeletal muscle. Skeletal muscles are the only muscles that can be consciously controlled. They are attached to bones, and contracting the muscles causes movement of those bones. Any action that a person consciously undertakes involves the use of skeletal muscles.
Which system allows for movement within the body?
The muscular system allows for movement within the body, for example, during digestion or urination. Smooth muscles in the gastrointestinal or GI tract control digestion. The GI tract stretches from the mouth to the anus. Food moves through the digestive system with a wave-like motion called peristalsis.

Cardiac muscle. Located only in the heart, cardiac muscle pumps blood around the body. Cardiac muscle stimulates its own contractions that form our heartbeat. Signals from the nervous system control the rate of contraction. This type of muscle is strong and acts involuntarily.
What muscles help with posture?
Skeletal muscles help keep the body in the correct position when someone is sitting or standing. This is known as posture. Good posture relies on strong, flexible muscles. Stiff, weak, or tight muscles contribute to poor posture and misalignment of the body.

What are the functions of the muscular system?
Center. The five main functions of the muscular system are movement, support, protection, heat generation and blood circulation . The muscular system is like a machine that converts chemical energy from food into mechanical energy. The five main functions of the muscular system are movement, support, protection, heat generation and blood circulation:
What is the function of skeletal muscles?
Skeletal muscles, particularly of the body wall, cushion the body's internal organs (abdominal cavity) from force applied to the exterior of the body. 4. Heat generation. Heat is a waste product of muscle metabolism, which helps maintain an internal body temperature of 98.6 F. Shivering is a mechanism of the muscular system ...
What muscles pull on the bones?
Skeletal muscles pull on the bones causing movements at the joints. Skeletal muscles pull on the soft tissues of the face causing facial expressions. Movement caused by the respiratory muscles enables breathing. 2.
What are the three parts of the muscular system?
The muscular system consists of skeletal, smooth and cardiac muscles: Skeletal muscles: These create movement in the body. There are nearly 700 skeletal muscles and make up about 40% of a person’s body weight. Smooth muscles: These are involuntary muscles that line the walls of the blood vessels and viscera (organs in the abdominal cavity).
What are the muscles that make up the body?
Skeletal muscles: These create movement in the body. There are nearly 700 skeletal muscles and make up about 40% of a person’s body weight. Smooth muscles: These are involuntary muscles that line the walls of the blood vessels and viscera (organs in the abdominal cavity).
Which muscles are involuntary?
Smooth muscles: These are involuntary muscles that line the walls of the blood vessels and viscera (organs in the abdominal cavity). Cardiac muscles: These cause the heart to contract and expand properly.
What are the nutrients that help the muscular system?
Whole grains, fruits and vegetables contribute to a healthy muscular and skeletal system. As carbohydrates are broken down into glucose, they increase insulin levels in the blood, which causes adenosine triphosphate (ATP) to be carried to the muscles around the body.
What is the function of the muscular system?

Why do muscles act as cushions?
The muscles acts as cushions to protect bones and organs, this can be done due to the agonist and antagonist movements (when a muscles pulls forward, there is another muscle to pull backwards) and the contraction movements it has, this help absorb impacts, reduce friction and stress in joints and other tissues.

How The Muscular System Works
Mobility
- The muscular system’s main function is to allow movement. When muscles contract, they contribute to gross and fine movement. Gross movement refers to large, coordinated motions and includes: 1. walking 2. running 3. swimming Fine movement involves smaller movements, such as: 1. writing 2. speaking 3. facial expressions The smaller skeletal muscles ...
Stability
- Muscle tendons stretch over joints and contribute to joint stability. Muscle tendons in the knee joint and the shoulder joint are crucial in stabilization. The core muscles are those in the abdomen, back, and pelvis, and they also stabilize the body and assist in tasks, such as lifting weights.
Posture
- Skeletal muscles help keep the body in the correct position when someone is sitting or standing. This is known as posture. Good posture relies on strong, flexible muscles. Stiff, weak, or tight muscles contribute to poor posture and misalignment of the body. Long-term, bad posture leads to joint and muscle pain in the shoulders, back, neck, and elsewhere.
Circulation
- The heart is a muscle that pumps blood throughout the body. The movement of the heart is outside of conscious control, and it contracts automatically when stimulated by electrical signals. Smooth muscle in the arteries and veins plays a further role in the circulation of blood around the body. These muscles maintain blood pressure and circulation in the event of blood loss or dehy…
Respiration
- Breathing involves the use of the diaphragm muscle. The diaphragm is a dome-shaped muscle located below the lungs. When the diaphragm contracts, it pushes downward, causing the chest cavity to get bigger. The lungs then fill with air. When the diaphragm muscle relaxes, it pushes air out of the lungs. When someone wants to breath more deeply, it requires help from other muscl…
Digestion
- Smooth muscles in the gastrointestinal or GI tract control digestion. The GI tract stretches from the mouth to the anus. Food moves through the digestive system with a wave-like motion called peristalsis. Muscles in the walls of the hollow organs contract and relax to cause this movement, which pushes food through the esophagus into the stomach. The upper muscle in the stomach r…
Urination
- The urinary system comprises both smooth and skeletal muscles, including those in the: 1. bladder 2. kidneys 3. penis or vagina 4. prostate 5. ureters 6. urethra The muscles and nerves must work together to hold and release urine from the bladder. Urinary problems, such as poor bladder control or retention of urine, are caused by damage to the nerves that carry signals to th…
Childbirth
- Smooth muscles in the uterus expand and contract during childbirth. These movements push the baby through the vagina. Also, the pelvic floor muscles help to guide the baby’s head down the birth canal.
Vision
- Six skeletal muscles around the eye control its movements. These muscles work quickly and precisely, and allow the eye to: 1. maintain a stable image 2. scan the surrounding area 3. track moving objects If someone experiences damage to their eye muscles, it can impair their vision.
