#1. Which of the following muscular disorders is inherited?

tetany is muscular spasm due to low calcium in body fluid.

Myasthenia gravis is an anto immume disorder leading to paralysis of skeletal muscles.

Botulism is rare and dangerous type of food poisoning caused by bacterium Clostridium Botulinum.

#2. Select the correct option.

#3. The pivot joint between atlas and axis is a type of

Synovial joints are freely movable joint which allow considerable movements. Pivot joint is a type of synovial joint which provide rotational movement as in between atlas and axis vertebrae of vertebral column.

#4. Name the ion responsible for unmasking of active sites for myosin for cross-bridge activity during muscle contraction.

Calcium ions bind with TpC unit of troponin which is responsible for unmasking of active sites for myosin for crossbridge activity during muscles contraction.

#5. Lack of relaxation between successive stimuli in sustained muscle contraction is known as

Sustained muscle contraction due to repeated stimulus is known as tetanus.

#6. Which of the following is not a function of the skeletal system?

Formation of RBC i.e. erythropoiesis occurs in bone marrow.

#7. Which of the following joints would allow no movement?

In fibrous joints, bones are firmly fixed together by strong collagen fibres.

#8. Glenoid cavity articulates

Scapula has a shallow articular surface called glenoid cavity. This articulates with the head of the humerus to form the shoulder joint.

#9. Stimulation of a muscle fibre by a motor neuron occurs at

The junction between a motor neuron and the sarcolemma of the muscle fibre is called neuromuscular junction or motor end plate.

#10. Select the correct statement with respect to locomotion in humans:

The vertebral column has 12 thoracic vertebrae. The joint between adjacent vertebrae is a cartilaginous joint.

A decreased level of estrogen in female causes osteoporosis.

#11. The H-zone in the skeletal muscle fibre is due to

#12. The type of muscles present in our

Muscles of limb are striated and voluntary.

Muscles of Heart are striated and Involuntary.

Muscles of intestine are unstriated and involuntary.

#13. Low Ca++ in the body fluid may be the cause of

Low level of calcium in the extracellular fluid / blood plasma leads to increase in the excitability of the excitatory cells i.e., muscles and nerves and thus muscle shows sustained contracted state known as tetany.

Gout : due to accumulation of uric acid.

Anaemia : deficiency of iron.

Angina pectoris : A symptom of acute chest pain appears when not enough oxygen is reaching the heart muscle.

#14. Select the true statement.

A band is present in the middle of the sarcomere.

H-zone is present in the middle of the A-band

M-line is present in the middle of H-zone.

#15. Which of the following muscles are not under the voluntary control of nervous system?

In urinary bladder involuntary smooth muscle fibres are present.

Pharynx, oesophagus and tongue are under the voluntary control.

#16. In a contracted skeletal muscle fibre

In a contracted muscle fibre, following happens –

  •  H-zone shortens
  •  I-band shortens
  •  A-band remains constant.

#17. The lactic acid generated during muscle contraction is finally converted to glycogen in

#18. 80% of the lactic acid is converted to _______ in the liver.

Just Above Question we mentioned about this topic

#19. Tongue bone is

Hyoid bone : is also known as tongue bone because tongue is attached to this single bone.

Mandible : Jaw bone

Coccyx : tail bone

#20. The two cells of the body which show pseudopodial movements are

Neutrophils (WBCs) and macrophages show pseudopodial movement.

#21. The muscle is a specialised tissue which originates from

Specialised tissue such as muscle, bones and cartilage originate from mesoderm.

#22. A collagenous sheath of connective tissue layer holding all the muscle bundles together is

#23. The sheath covering a single bundle of muscle fibres is

The sheath that covers the muscle is epimysium.

Mesoderm – germ layer

The sheath that covers a single muscle fibre is endomysium.

#24. Tendons connect

Tendons : Connect muscles to bones.

Ligament : Connect bone to bone.

#25. The plasma membrane of a muscle fibre is called

Sarcolemma : Plasma membrane of the muscle fibre

Sarcoplasma : Cytoplasm of muscle fibre

Sarcoplasmic Reticulum : Endoplasmic reticulum of the muscle fibre.

Syncytial : A cell having multiple nuclei assumed to be formed by fusion.

#26. The structural and functional unit of myofibril which contracts to cause movement is called

The structural and functional unit of myofibril is known as sarcomere which is the section between two Z-lines.

#27. Which one of the proteins is not a part of thin myofilament?

Thick myofilaments : myosin

Thin myofilaments : actin, tropomyosin, troponin.

#28. The monomeric protein which polymerises to form myosin is

Meromyosin is the monomer of myosin.

#29. ATP binding site is located on

ATP binding site is located on the myosin head where ATPase is present.
