(1 Mark)
In the cardiac conduction system, which structure possesses the fastest intrinsic rate of spontaneous action potential generation?
A
Atrioventricular (AV) node
B
Bundle of His
C
Purkinje fibers
D
Sinoatrial (SA) node
✓ Correct
💡
Step-by-Step Explanation & Concept Rationale
The Sinoatrial (SA) node has the highest intrinsic pacing rate (60-100 bpm) and functions as the primary physiological pacemaker of the human heart.
Q. 3
Medical Sciences
Difficulty: Hard
(1 Mark)
The primary blood supply to the head and neck of the femur, vulnerable to avascular necrosis following femoral neck fractures, is derived mainly from the:
A
Medial circumflex femoral artery
✓ Correct
B
Lateral circumflex femoral artery
C
Obturator artery
D
Inferior gluteal artery
💡
Step-by-Step Explanation & Concept Rationale
The medial circumflex femoral artery provides the principal retinacular blood supply to the femoral head and neck; intracapsular fractures often disrupt these branches leading to avascular necrosis.
Q. 4
Medical Sciences
Difficulty: Easy
(1 Mark)
Which of the following cells in the gastric mucosa secrete hydrochloric acid (HCl) and intrinsic factor?
A
Chief (zymogenic) cells
B
Parietal (oxyntic) cells
✓ Correct
C

Q. 5
Medical Sciences
Difficulty: Medium
(1 Mark)
Injury to the common peroneal (fibular) nerve at the fibular neck characteristically results in:
A
Loss of plantar flexion (calcaneovalgus)
B
Foot drop with loss of dorsiflexion and eversion
✓ Correct
C
Loss of sensation on the medial sole
D
Weakness in knee extension
💡
Step-by-Step Explanation & Concept Rationale
The common peroneal nerve wraps around the neck of the fibula; damage impairs the anterior and lateral compartment leg muscles causing foot drop (loss of dorsiflexion) and high-stepping gait.
Q. 6
Medical Sciences
Difficulty: Easy
(1 Mark)

A
Follicle-stimulating hormone (FSH)
B
Luteinizing hormone (LH)
✓ Correct
C

Tidal volume (TV)
D
Inspiratory reserve volume (IRV)
💡
Step-by-Step Explanation & Concept Rationale
Residual volume (RV), along with Functional Residual Capacity (FRC) and Total Lung Capacity (TLC), cannot be measured by spirometry because air remains in the lungs after maximal expiration.

Q. 10
Medical Sciences
Difficulty: Medium
(1 Mark)
Which factor shifting the oxyhemoglobin dissociation curve to the right increases oxygen unloading to tissues (Bohr effect)?
A
Decreased temperature
B
Increased blood pH (alkalosis)
C
Increased PCO2, increased H+ (acidosis), and increased 2,3-BPG
✓ Correct
D
Decreased 2,3-BPG
💡
Step-by-Step Explanation & Concept Rationale
A rightward shift reduces hemoglobin's affinity for oxygen, facilitating oxygen release to metabolically active tissues; it is caused by increased PCO2, acidosis (low pH), hyperthermia, and elevated 2,3-BPG.

✓ Correct
C
Excrete calcium and retain phosphate
D

Q. 17
Medical Sciences
Difficulty: Hard
(1 Mark)
Which laryngeal muscle is the sole abductor of the vocal cords?
A
Lateral cricoarytenoid
B
Posterior cricoarytenoid
✓ Correct
C

D
Thyroarytenoid
💡
Step-by-Step Explanation & Concept Rationale
The posterior cricoarytenoid muscles are the only muscles that abduct (open) the vocal folds; bilateral injury to their nerve supply (recurrent laryngeal nerve) can cause life-threatening airway obstruction.
