2026&2027
1. A patient sustains a fracture involving the surgical neck of the humerus. Which nerve is
most likely to be injured?
A. Radial nerve
B. Axillary nerve
C. Median nerve
D. Ulnar nerve
The axillary nerve passes around the surgical neck of the humerus and supplies the deltoid
and teres minor muscles. Injury can cause impaired shoulder abduction and sensory loss over
the lateral shoulder.
2. Which chamber of the heart normally receives oxygenated blood returning from the
pulmonary circulation?
A. Right atrium
B. Right ventricle
C. Left atrium
D. Left ventricle
The left atrium receives oxygenated blood from the lungs through the pulmonary veins and
passes it to the left ventricle for systemic circulation.
3. A patient has difficulty initiating swallowing after a neurological injury. Which cranial
nerve provides major motor innervation to the muscles involved in swallowing?
A. Vagus nerve
B. Optic nerve
C. Olfactory nerve
D. Vestibulocochlear nerve
The vagus nerve supplies most of the muscles of the pharynx and larynx and is therefore
essential for coordinated swallowing and airway protection.
4. Which structure is primarily responsible for filtering blood and initiating urine
formation?
A. Loop of Henle
B. Collecting duct
C. Renal pelvis
D. Glomerulus
,The glomerulus is a capillary network within the renal corpuscle where blood filtration begins.
Filtrate then enters the renal tubule for further processing.
5. Which anatomical plane divides the body into equal right and left portions?
A. Transverse plane
B. Midsagittal plane
C. Frontal plane
D. Oblique plane
A midsagittal plane passes through the body's midline and divides it into equal right and left
halves.
6. A patient experiences loss of sensation and motor function in the lower limb following
spinal cord trauma. Which region of the vertebral column contains the spinal cord's
lumbar enlargement?
A. Cervical region
B. Thoracic region
C. Lumbar region
D. Sacral region
The lumbar enlargement of the spinal cord contains neurons and pathways serving much of
the lower limb. It is located within the lower thoracic to upper lumbar vertebral levels.
7. Which muscle is the primary muscle responsible for quiet inspiration?
A. Diaphragm
B. Rectus abdominis
C. Internal intercostal
D. Pectoralis minor
The diaphragm contracts and moves inferiorly during inspiration, increasing thoracic volume
and creating the pressure gradient necessary for air to enter the lungs.
8. Which structure prevents food from entering the trachea during swallowing?
A. Uvula
B. Vocal folds
C. Epiglottis
D. Soft palate
The epiglottis helps cover the laryngeal inlet during swallowing, directing food toward the
esophagus and helping protect the lower respiratory tract.
9. Which blood vessel carries deoxygenated blood from the right ventricle toward the
lungs?
A. Pulmonary artery
B. Pulmonary vein
,C. Aorta
D. Superior vena cava
The pulmonary arteries carry deoxygenated blood from the right ventricle to the lungs for gas
exchange.
10. Which organ is primarily located in the right upper quadrant of the abdomen?
A. Spleen
B. Liver
C. Sigmoid colon
D. Urinary bladder
Most of the liver occupies the right upper quadrant beneath the diaphragm, although it
extends across the midline into the left upper quadrant.
11. Which type of joint permits the greatest range of movement?
A. Pivot joint
B. Hinge joint
C. Ball-and-socket joint
D. Saddle joint
Ball-and-socket joints, such as the shoulder and hip, permit movement in multiple planes,
including flexion, extension, abduction, adduction, rotation, and circumduction.
12. A patient develops weakness in knee extension after an injury affecting the anterior
thigh. Which muscle is primarily responsible for this movement?
A. Hamstrings
B. Sartorius
C. Gastrocnemius
D. Quadriceps femoris
The quadriceps femoris group extends the knee and is essential for standing, walking,
climbing stairs, and rising from a seated position.
13. Which part of the brain is primarily responsible for maintaining balance and
coordinating voluntary movement?
A. Cerebellum
B. Hypothalamus
C. Medulla oblongata
D. Frontal lobe
The cerebellum coordinates movement, posture, balance, and motor learning. Damage
commonly produces ataxia and impaired coordination.
, 14. Which structure connects the pharynx to the stomach?
A. Trachea
B. Esophagus
C. Duodenum
D. Jejunum
The esophagus is a muscular tube that transports swallowed material from the pharynx to
the stomach through coordinated peristaltic contractions.
15. Which hormone-producing organ is located in the anterior neck and wraps around the
trachea?
A. Thyroid gland
B. Pituitary gland
C. Adrenal gland
D. Pancreas
The thyroid gland lies anterior to the trachea and produces thyroid hormones that influence
metabolic activity, growth, and development.
16. Which portion of the small intestine is the first segment after the stomach?
A. Ileum
B. Jejunum
C. Duodenum
D. Cecum
The duodenum is the first portion of the small intestine and receives acidic gastric contents
along with bile and pancreatic secretions.
17. Which cranial nerve is responsible for transmitting visual information from the retina
to the brain?
A. Oculomotor nerve
B. Optic nerve
C. Trigeminal nerve
D. Facial nerve
The optic nerve, cranial nerve II, carries sensory information generated by retinal
photoreceptors to the brain for visual processing.
18. A patient cannot flex the forearm effectively after an upper-arm injury. Which major
muscle is primarily responsible for elbow flexion?
A. Triceps brachii
B. Deltoid
C. Biceps brachii
D. Latissimus dorsi
