SECTION 1: ANATOMY & KINESIOLOGY (Questions 1-30)
Question 1
Which of the following describes the anatomical position?
A) Standing, arms crossed, palms facing posterior
B) Standing, arms at sides, palms facing anterior, feet parallel
C) Supine, arms at sides, palms facing down
D) Prone, arms overhead, palms facing down
Rationale: The anatomical position is standardized as standing upright, facing forward,
arms at the sides, palms facing forward (anterior), and feet parallel. This position serves as
the reference point for all directional terms used in anatomy and kinesiology .
,Question 2
What is the primary action of the latissimus dorsi muscle?
A) Shoulder abduction and upward rotation
B) Shoulder adduction, extension, and internal rotation
C) Elbow flexion
D) Scapular protraction
Rationale: The latissimus dorsi ("lats") is a large back muscle that adducts, extends, and
internally rotates the humerus. It is a prime mover in pull-ups, rows, and lat pulldowns .
Question 3
Which plane of motion divides the body into left and right halves?
A) Frontal (coronal) plane
B) Sagittal plane
C) Transverse (horizontal) plane
D) Oblique plane
Rationale: The sagittal plane divides the body into left and right halves and contains
forward/backward movements such as flexion and extension. Biceps curls, squats, lunges,
and walking all occur primarily in the sagittal plane .
Question 4
The antagonist opposes the action of the agonist. During elbow flexion, which muscle
acts as the antagonist?
A) Biceps brachii
B) Triceps brachii
C) Brachialis
D) Brachioradialis
,Rationale: The antagonist opposes the action of the agonist. During elbow flexion
(agonist: biceps brachii), the triceps brachii (elbow extensor) relaxes and lengthens as the
antagonist to control the movement .
Question 5
Which of the following muscles is a prime mover in hip extension?
A) Iliopsoas
B) Rectus femoris
C) Gluteus maximus
D) Tensor fasciae latae
Rationale: The gluteus maximus is the primary hip extensor, working during squats,
deadlifts, lunges, and stair climbing. The iliopsoas is a hip flexor, not an extensor .
Question 6
The scapula is an example of which type of bone?
A) Long bone
B) Short bone
C) Flat bone
D) Irregular bone
Rationale: The scapula (shoulder blade) is a flat bone. Flat bones provide broad surfaces
for muscle attachment and protection (e.g., skull, ribs, sternum, scapula) .
Question 7
What type of joint is the knee (tibiofemoral joint)?
, A) Ball and socket
B) Hinge joint (modified)
C) Pivot joint
D) Saddle joint
Rationale: The knee is a modified hinge joint that allows primarily flexion and extension,
with some rotational movement when the knee is flexed .
Question 8
What is the origin of the biceps brachii?
A) Radial tuberosity
B) Coracoid process and supraglenoid tubercle of scapula
C) Humerus shaft
D) Clavicle
Rationale: The biceps brachii has two heads: the long head originates from the
supraglenoid tubercle of the scapula, and the short head originates from the coracoid
process of the scapula. Its insertion is the radial tuberosity .
Question 9
Which muscle group is responsible for shoulder abduction (raising the arm to the side)?
A) Pectoralis major
B) Latissimus dorsi
C) Deltoid (middle fibers) and supraspinatus
D) Teres major
Rationale: The middle deltoid is the prime mover for shoulder abduction, with the
supraspinatus assisting as a synergist during the first 15 degrees of abduction .
