Massage Therapy Anatomy & Physiology 1 — Questions and Answers
Question 1: Which muscle is primarily responsible for shoulder abduction?
- Deltoid (Correct answer)
- Pectoralis major
- Trapezius
- Latissimus dorsi
Correct answer: Deltoid
The deltoid muscle, particularly its middle fibers, is the primary mover for shoulder abduction.
Question 2: The brachial plexus originates from which spinal levels?
- C5–T1 (Correct answer)
- C1–C5
- T1–T6
- C3–C8
Correct answer: C5–T1
The brachial plexus arises from the ventral rami of spinal nerves C5 through T1.
Question 3: Which type of synovial joint allows movement in all planes?
- Ball-and-socket (Correct answer)
- Hinge
- Pivot
- Saddle
Correct answer: Ball-and-socket
Ball-and-socket joints, like the hip and shoulder, allow multiaxial movement in all planes.
Question 4: What is the function of the lymphatic system in relation to massage?
- Removes metabolic waste and excess interstitial fluid (Correct answer)
- Produces red blood cells
- Regulates blood pressure
- Secretes digestive enzymes
Correct answer: Removes metabolic waste and excess interstitial fluid
The lymphatic system drains excess interstitial fluid and metabolic waste, a process enhanced by massage.
Question 5: The origin of the biceps brachii (long head) is at the:
- Supraglenoid tubercle (Correct answer)
- Coracoid process
- Radial tuberosity
- Olecranon
Correct answer: Supraglenoid tubercle
The long head of the biceps brachii originates from the supraglenoid tubercle of the scapula.
Question 6: Which layer of fascia directly surrounds individual muscle fibers?
- Endomysium (Correct answer)
- Perimysium
- Epimysium
- Deep fascia
Correct answer: Endomysium
