MCQ on Muscular System

The muscular system is an organ system that is primarily involved in body movement. Nearly 700 muscles are related to the skeletal system’s bones, which account for almost half of a person’s body weight. Blood veins, skeletal muscle tissue, tendons and nerves make up each muscle, making it a unique organ. Blood vessels, the heart, and digestive system all contain muscle tissues.

Muscle tissues are divided into three categories which are Cardiac, Smooth, and Skeletal.

Q1. What are the three categories of the muscles?

1. Tendons, Ligaments, Joints
2. Cardiac, Smooth, Skeletal
3. Flexion, Smooth, Extension
4. Skeletal, Stringy, Smooth

Answer. Cardiac, Smooth, Skeletal is the correct answer. Cardiac, Smooth and Skeletal are the three types of muscles.

Q2. Smooth muscle is responsible for

1. Voluntary movements of body.
2. Carries out most of the involuntary processes such as digestion as well as pumping the blood through arteries.
3. Control of all the involuntary movements
4. None of the above

Answer. Smooth muscle is responsible for carries out most of the involuntary processes such as digestion as well as pumping the blood through arteries. Therefore, option 2 is the right answer.

Q3.  Skeletal muscle is responsible for

1. Carries out most of the involuntary processes such as digestion as well as pumping the blood through arteries.
2. Control of most of the involuntary movements
3. Voluntary movements of body.
4. None of the above.

Answer. Voluntary movements of body is the correct answer. Body movements like typing, extending the arm, breathing, writing, and so on are all controlled by the skeletal muscles. Muscle contraction creates movement by pulling on the tendons on the bones.

Q4. How many muscles are there in the body of human?

1. 340
2. 560
3. 640
4. 860

Answer. 640 is the right answer. Approximate 640 muscles are found in the body of human.

Q5. Tendons connect bone and

1. Bone
2. Ligaments
3. Muscle
4. Cartilage

Answer. Muscle is the right answer. The tight, thick band of the fibrous tissue which joins muscle to bone is termed as a tendon. Collagen fibres make up tendon tissue.

Q6.  Which of the following is connected by the ligaments?

1. Cartilage to the bone
2. Muscle to the bone
3. Bone to the Bone
4. Tendons to the muscles

Answer. Bone to the Bone is the right answer. Ligaments are the short bands of tough and flexible tissue which are made up of many individual fibres that link the body’s bones. Ligaments connect the majority of bones in the body. A ligament’s job is to limit the amount of mobility between the bones in a passive way.

Q7. How many types of muscles are present in the body?

1. 4
2. 2
3. 3
4. 5

Answer. 3 is the right answer. There are 3 muscles present in the body.

Q8. Where cardiac muscle is found?

1. Skin
2. Lungs
3. Bones
4. Heart

Answer. Heart is the right answer. Cardiac muscle cells are striated and controlled involuntarily and are situated in the heart’s walls. Smooth muscle fibres, with the exception of the heart, are found in the walls of the hollow visceral organs, are spindle-shaped, and are controlled involuntarily.

Q9.  Voluntary muscle is a

1. Control over muscle 
2. No control over muscle
3. Muscle function automatically
4. Muscles are fused together

Answer. Control over muscle is the right answer. Voluntary muscles are skeletal body muscles that link to bones. They have cognitive control over the movement of limbs, the head, neck and other body components.

Q10. Elastic bundles of tissue which perform various functions is termed as

1. Tendons
2. Ligaments
3. Joints
4. Muscle

Answer. Muscle is the right answer. Elastic bundles of tissue which perform various functions are termed as muscle.

Q11. Respiration in the absence of the oxygen is

1. Anaerobic
2. Aerobic
3. Mastication
4. None of the above

Answer. Anaerobic is the correct answer. 

Glucose is broken down without oxygen in anaerobic respiration.

Energy is transferred from glucose to the cell through a chemical process.

Lactic acid is produced instead of water and carbon dioxide during anaerobic respiration. As a result, anaerobic respiration is defined as respiration carried out in the absence of oxygen.

Q12. What makes the muscles to be strong?

1. Diet
2. Sleeping
3. Food
4. Exercise

Answer. The right answer is exercise. The muscles become stronger when we exercise daily.

Q13. Liquid produced during the contraction of muscle due to anaerobic breakdown is

1. Glucose
2. Oxygen
3. Lactic Acid
4. Sugar

Answer. Lactic Acid is the right answer. Lactic acid is produced during the contraction of muscle due to the anaerobic breakdown. Lactate is formed in this process.

Q14. Use of oxygen to breakdown the food for the formation of energy is

1. Anaerobic respiration
2. Aerobic respiration
3. Cellular Respiration
4. Oxygen

Answer. Cellular Respiration is the correct answer. Cellular respiration is a process of breaking down the food to produce energy. Most organisms have cellular respiration taking on within their cells.

Q15. The Muscular muscle is a/an

1. Large system
2. Organ system
3. Unique system
4. Small system

Answer. Organ system is the right answer. The muscular system is an organ system that is primarily involved in body movement. The muscular system’s most visible function is the movement.

Q16. Muscular System makes nearly what percent of the weight of the human body?

1. 20%
2. 40%
3. 70%
4. 50%

Answer. 50% is the right answer. The muscular system accounts for about half of the human body’s weight. Muscles generate the forces that allow the body to move.

Q17. Which of the following is not a kind or type of muscle?

1. Cardiac
2. Skeletal
3. Sesamoids.
4. Smooth

Answer. Sesamoids is the right answer. Muscle tissues are divided into three categories which are Cardiac, Smooth, and Skeletal. 

Sesamoids are bones which are embedded in tendons.
