Massage Therapist Kinesiology 2 — Questions and Answers
Question 1: Which plane of motion divides the body into left and right halves?
- Frontal plane
- Transverse plane
- Sagittal plane (Correct answer)
- Coronal plane
Correct answer: Sagittal plane
The sagittal plane divides the body into left and right halves and is the plane in which flexion and extension occur.
Question 2: During elbow flexion, the biceps brachii acts as the prime mover. What role does the triceps brachii play?
- Synergist
- Fixator
- Antagonist (Correct answer)
- Neutralizer
Correct answer: Antagonist
The triceps brachii acts as the antagonist during elbow flexion, opposing the action of the biceps brachii.
Question 3: Which type of muscle contraction occurs when the muscle lengthens while producing tension?
- Isometric contraction
- Concentric contraction
- Eccentric contraction (Correct answer)
- Isotonic contraction
Correct answer: Eccentric contraction
Eccentric contraction occurs when a muscle produces tension while lengthening, such as when slowly lowering a weight.
Question 4: The gluteus medius primarily performs which action at the hip?
- Hip extension
- Hip flexion
- Hip abduction (Correct answer)
- Hip adduction
Correct answer: Hip abduction
The gluteus medius is the primary hip abductor, moving the leg away from the body's midline.
Question 5: Which connective tissue attaches muscle to bone?
- Ligament
- Fascia
- Cartilage
- Tendon (Correct answer)
Correct answer: Tendon
Tendons are dense connective tissues that attach muscle to bone and transmit the force of muscular contraction.
Question 6: Dorsiflexion of the foot involves which movement?
- Pointing the toes downward
- Rotating the foot inward
- Pulling the toes upward toward the shin (Correct answer)
- Turning the foot outward
Correct answer: Pulling the toes upward toward the shin
Dorsiflexion decreases the angle between the dorsum of the foot and the anterior leg, pulling the toes toward the shin.
Question 7: Which muscle is the primary hip flexor?
- Rectus femoris
- Iliopsoas (Correct answer)
- Sartorius
- Tensor fasciae latae
Correct answer: Iliopsoas
The iliopsoas, composed of the iliacus and psoas major, is the primary hip flexor muscle.
