COMPLETE QUESTIONS WITH VERIFIED ANSWERS AND
DETAILED RATIONALES
1. Which bony structure articulates with the humerus to form the
glenohumeral joint?
A) Radius
B) Clavicle
C) Scapula
D) Sternum
Correct Answer: C
Rationale: The glenohumeral joint is the shoulder joint, which is formed
by the articulation of the head of the humerus and the glenoid fossa of
the scapula.
2. The acronym SITS is used to remember which group of muscles?
A) The quadriceps
B) The hamstrings
C) The rotator cuff
D) The abdominal muscles
Correct Answer: C
Rationale: SITS stands for Supraspinatus, Infraspinatus, Teres Minor,
and Subscapularis, which are the four muscles that make up the rotator
cuff.
3. A loss of muscle tone and strength is medically defined as:
A) Hypertrophy
,B) Atrophy
C) Spasm
D) Contracture
Correct Answer: B
Rationale: Atrophy is the term used to describe the wasting away or
decrease in size and strength of a muscle, often due to disuse or injury.
4. Which ligament provides stability to the Acromioclavicular (AC)
joint?
A) Deltoid ligament
B) Coracoclavicular ligament
C) Anterior talofibular ligament
D) Tibial collateral ligament
Correct Answer: B
Rationale: The Coracoclavicular ligaments are strong ligaments that
connect the clavicle to the coracoid process of the scapula, providing
significant stability to the AC joint.
5. Which type of muscle contraction involves holding a position, such
as maintaining a neutral spine?
A) Isotonic
B) Isokinetic
C) Isometric
D) Eccentric
Correct Answer: C
Rationale: An isometric contraction occurs when the muscle generates
tension without changing its length, which is essential for stabilization
and posture.
,6. The Pes Anserine, or "Goose Foot," is the insertion point for which
three muscles?
A) Rectus Femoris, Vastus Medialis, Vastus Lateralis
B) Gracilis, Sartorius, Semitendinosus
C) Biceps Femoris, Semitendinosus, Semimembranosus
D) Tibialis Anterior, Peroneus Longus, Gastrocnemius
Correct Answer: B
Rationale: The Pes Anserine is the conjoined tendon of the Gracilis,
Sartorius, and Semitendinosus muscles, which inserts on the medial
tibia.
7. What is the most common direction for an elbow dislocation?
A) Anterior
B) Medial
C) Lateral
D) Posterior
Correct Answer: D
Rationale: Most elbow dislocations are posterior, meaning the ulna and

B) Knock-kneed
C) Flat feet
D) Scoliosis
Correct Answer: B
Rationale: Genu Valgum refers to the condition where the knees angle
inward and touch each other when the legs are straightened, commonly
known as "knock-knees."
, 9. Which muscle's tendon connects to the head of the fibula?
A) Rectus Femoris
B) Semitendinosus
C) Biceps Femoris
D) Gracilis
Correct Answer: C
Rationale: The Biceps Femoris, one of the hamstring muscles, has its
insertion point on the head of the fibula.
10. The body plane that divides it into left and right halves is the:
A) Coronal Plane
B) Transverse Plane
C) Midsagittal Plane
D) Frontal Plane
Correct Answer: C
Rationale: The midsagittal plane is a vertical plane that divides the body
into equal left and right halves.
11. A ligament connects which two structures?
A) Muscle to bone
B) Bone to bone
C) Muscle to muscle
D) Bone to cartilage
Correct Answer: B
Rationale: Ligaments are tough, fibrous bands of connective tissue that
connect bone to bone, providing stability to joints.
12. How many cervical vertebrae are there in the human spine?
A) 5
B) 7
