Which of the following joints is present between the phalanges?

Ball and socket joint
Hinge joint
Pivot joint
Gliding joint
2

Hinge joints, like those in the fingers (phalanges), allow movement in one plane only.

Which of the following bones is part of the axial skeleton?

Humerus
Femur
Ribs
Scapula
3

The ribs are part of the axial skeleton, which includes the skull, vertebral column, and sternum.

Which of the following conditions is characterized by age-related bone loss?

Arthritis
Osteoporosis
Gout
Tetany
2

Osteoporosis is a condition where bone mass decreases with age, increasing the risk of fractures.

Which of the following statements about actin filaments is incorrect?

Actin filaments are composed of 'F' actin polymers.
Troponin is distributed at regular intervals on actin filaments.
Myosin binds directly to tropomyosin during contraction.
Actin filaments are thinner compared to myosin filaments.
3

Myosin does not bind directly to tropomyosin; it binds to actin filaments after troponin removes the masking effect​.

Which of the following bones belongs to the appendicular skeleton?

Sternum
Scapula
Vertebra
Ribs
2

The scapula is part of the appendicular skeleton, while the sternum, vertebrae, and ribs belong to the axial skeleton​.

Which joint is correctly matched with its type?

Hinge joint - Shoulder joint
Pivot joint - Between atlas and axis
Gliding joint - Hip joint
Ball and socket joint - Knee joint
2

Which type of movement is seen in ciliated epithelial cells?

Amoeboid movement
Ciliary movement
Muscular movement
Gliding movement
2

Ciliary movement is seen in ciliated epithelial cells, such as those in the respiratory tract, which help move mucus and trapped particles.

Which part of the muscle fiber stores calcium ions required for muscle contraction?

Sarcolemma
Sarcoplasmic reticulum
Myofibrils
T-tubules
2

The sarcoplasmic reticulum stores calcium ions, which are essential for muscle contraction.

Which type of synovial joint is found between the carpal bones of the wrist?

Ball and socket joint
Hinge joint
Gliding joint
Pivot joint
3

Gliding joints allow limited movement between flat bones, such as the carpal bones of the wrist.
