AFAA EXAM SCRIPT COMPLETE
QUESTIONS AND ANSWERS
◉ Midline. Answer: Imaginary line that splits the body into two
equal parts.
◉ Central Nervous System (CNS). Answer: Brain and spinal cord;
coordinates activity of body parts
◉ Peripheral Nervous System (PNS). Answer: All nerves branching
off spinal cord; extending out of the body.
◉ Mechanorecptors. Answer: Sense distortion in body tissue
◉ Kinetic Chain. Answer: Interrelation of nervous, muscular and
skeletal systems to create movement.
◉ Tendons. Answer: Connect muscle to bone, produce force, limited
blood flow, slow to repair.
◉ Type 1 (slow twitch) muscle tissue. Answer: More aerobic, slower
to reach maximum contraction; resistant to fatigue.
,◉ Type 2 (fast twitch) muscle tissue. Answer: more anaerobic;
produce more speed and strength; faster to fatigue
◉ Ligaments. Answer: Connect bone to bone, limited blood flow,
slow to repair
◉ Axial Skeleton. Answer: skull, rib cage, and vertebral column
◉ Appendicular. Answer: Bones of upper and lower extremities
◉ Non-synovial joints. Answer: No joint cavity or connective tissue;
little
◉ Synovial joints (Six Types). Answer: 1. Gliding
2. Condyloid
3. Hinge
4. Saddle
5. Pivot
6. Ball-and-Socket
Produces synovial fluid, has joint activity and connective tissue.
,◉ Gliding Joint. Answer: No axis of rotation, moves by sliding side to
side or back and forth ( carpals of the hand )
◉ Condyloid Joint. Answer: Moves predominantly in one play of
motion. (knee)
◉ Transverse Plane. Answer: Divides the body into top and bottom
halves; rotational movement.
◉ Hinge Joint. Answer: Uniaxial, moves predominantly in one plane
of motion. (Sagittal) (elbow)
◉ Saddle Joint. Answer: One bone fits like a saddle on another bone,
moves predominantly in tow planes ( sagittal, frontal ) (Thumb)
◉ Pivot Joint. Answer: Only one axis, moves predominantly in one
plane of motion (transverse) Example: Radioulnar
◉ Ball and socket joint. Answer: Most mobile of joints; moves in all
three planes of motion (shoulder)
◉ Optimal dynamic posture at the five kinetic chain checkpoint.
Answer: Feet- hip to shoulder width apart; pointed straight ahead;
Knees- soft and extended; in line with 2nd and 3rd toes
, LPHC- neutral; abs and glutes engaged.
Shoulders- back and down; no thoracic rounding.
Head/neck- cervical spine neutral
◉ Atria. Answer: Superior chambers; receive blood from outside the
heart
◉ Right Atrium. Answer: Gathers deoxygenated blood from body
◉ Sinoatrial (SA). Answer: Located in right atrium; receives signal to
contract; "pacemaker for the heart". Initiates the electrical impulses
that determine the heart rate
◉ Stroke Volume (SV). Answer: Amount of blood pumped with each
contraction
◉ What are the functions of blood?. Answer: transportation,
regulation, protection
◉ Anterior. Answer: Front of body
◉ Posterior. Answer: back of body
