Question 1: Bones act as a storehouse mainly for minerals such as:

Iodine and iron

Urea and bile

Calcium and phosphorus

Glucose and starch

Question 2: The fluid present in movable joints that lubricates the joint surfaces is:

Bile

Synovial fluid

Cerebrospinal fluid

Gastric juice

Question 3: Which type of muscles are attached to bones and are under our control?

Smooth muscles

Cardiac muscles

Ciliated muscles

Skeletal muscles

Question 4: Smooth muscles are found in:

Heart only

Walls of internal organs like stomach and intestine

Biceps

Skull

Question 5: The muscle found only in the heart is called:

Skeletal muscle

Voluntary muscle

Smooth muscle

Cardiac muscle

Question 6: Biceps and triceps in the upper arm work as:

Digestive enzymes

Excretory organs

Sensory receptors

Antagonistic pair

Question 7: When you bend your arm at the elbow, the biceps:

Contracts

Turns into tendon

Stops blood flow

Relaxes

Question 8: When you straighten your arm, the triceps:

Relaxes

Contracts

Filters blood

Produces bile

Question 9: Muscles are attached to bones with the help of:

Tendons

Ligaments

Cartilage

Capillaries

Question 10: Why do muscles usually work in pairs?

Because they store minerals

Because they can pull but cannot push

Because they digest food

Because they produce hormones

Question 11: The contraction and relaxation of diaphragm helps in:

Producing urine

Breathing

Filtering blood

Digesting fats

Question 12: Peristalsis in the alimentary canal is produced by:

Smooth muscles

Cardiac muscles

Skeletal muscles

Bone cells

Question 13: Muscle cramps during heavy exercise are commonly linked to buildup of:

Glucose

Bile

Urea

Lactic acid

Question 14: The basic function of muscles is to:

Exchange gases

Produce movement by contracting

Produce blood cells

Store urine

Question 15: Which of these is an example of involuntary muscle action?

Throwing a ball

Movement of food in intestine

Running

Writing

Question 16: Cardiac muscles show which special property?

No blood supply

Digestive enzyme secretion

Rhythmic contraction without fatigue

Voluntary control

Question 17: A student says 'all muscles are voluntary'. The correct statement is:

Only cardiac muscles are voluntary

All muscles are voluntary

All muscles are involuntary

Only skeletal muscles are voluntary; smooth and cardiac are involuntary

Question 18: Which structure connects muscle to bone at a joint?

Synovial fluid

Cartilage

Ligament

Tendon

Question 19: Which type of muscle is found in the walls of blood vessels?

Skeletal muscle

Bone marrow

Cardiac muscle

Smooth muscle

Question 20: The energy for muscle contraction is supplied directly by:

Starch granules

Bile salts

ATP

Urea
