What is the correct movement of the glenohumeral joint during the tricep pushdown
exercise?
a. dorsi flexion
b. no joint movement
c. extension
d. abduction
- answer- (b) no joint movement.
- The glenohumeral joint should experience no movement during arm exercises. Since the
elbow is a hinge joint any shoulder movement would negate the focus from the triceps
musculature. A common fault during triceps exercises is to combine elbow extension with
shoulder extension. Many exercisers "cheat" using the lats to assist with momentum forces;
seen when the humerus (upper arms) deviates backward and forward across the midaxillary
line during the eccentric and concentric phases.
What is the dual-action muscle of the quadriceps; allowing it to act upon both the hip and
knee joints?
a. vastus lateralis
, Page 2 of 28
b. biceps femoris
c. vastus intermedius
d. rectus femoris
- answer- (d) rectus femoris
- The quadriceps is comprised of four different muscles; the vastus lateralis, vastus medialis,
vastus intermedius and rectus femoris. The rectus femoris is the only quadriceps muscle that
crosses two joints - the hip and knee. The superior aspect of the rectus femoris originates at
the pelvis, resulting in hip flexion when contracted. The inferior portion inserts on the patella
via the quadriceps tendon causing knee extension.
What is the term used to describe the natural curvature of the cervical and lumbar spine?
a. lordotic
b. kyphotic
c. sciatic
d. thoracic
- answer- (a) lordotic
- A lordotic curve is the term used to describe the natural curvature of both the cervical spine
(C1-C7) and the lumbar spine (L1-L5). A natural lordotic curve is essential for support and
energy transfer. Excessive curvature is referred to as lordosis as seen during back
hyperextension. A kyphotic curve is the term used to describe a convex curvature of the
thoracic spine ( T1-T12).

All of the following are rotator cuff muscles, except:
a. infraspinatus
b. supraspinatus
c. levator scapulae
d. subscapularis
- answer- (c) levator scapulae
- The supraspinatus, infraspinatus, teres minor, and subscapularis make up the musculature of
the rotator cuff; often easily remembered through the acronym "SITS". The shoulder joint is a
shallow ball-and-socket joint formed by the scapula and humerus. The rotator cuff functions
for assist rotational motion and help counteract joint instability by stabilizing the humerus at
different angles.
Which muscle is responsible for the first 30 degrees of trunk flexion and is targeted during the
crunch movement?
a. obliques
b. iliopsoas
c. erector spinae
d. rectus abdominis
- answer- (d) rectus abdominis
