Multiple Choice:
Directions: Beneath each of the following questions are four lettered phrases or sentences marked
(a), (b), (c), and (d), but ONLY ONE best fits the answer. Please decide which one is the closest
correct answer. Then, write down the corresponding letter of the answer you have chosen on your
answer sheet.
Spiderman (蜘蛛人) jumped from a tower at
a speed of 5 km/sec. He landed down with
both hands first onto the grounds like the
picture on the right side. The landing
motion is defined from the moment when the
arm first contacted the ground to the moment
when the arm became straight again. This
motion was divided into two phases: (1) to
lower down his body through elbow flexion
of both arms and (2) to raise up the body with elbow extension. The duration for phase I is from
the time when both arms first contacted the ground to the time when his body was in the lowest
position while that for phase II is from the time when his body is in the lowest position to the time
when his elbows fully extended again. Please carefully answer the question set from 1 to 10.
1. The above statements to describe Spiderman’s landing motion are one kind of _____.
a. forensic description
b. anthropometric description
c. kinematic description
d. kinetic description
2. The left arm position in the picture above is _____.
a. both shoulder and elbow flexion
b. shoulder flexion and elbow extension
c. shoulder extension and elbow flexion d. both shoulder and elbow extension
3. The principal joint that to take place the elbow flexion/extension during this landing
motion is _____ that is a _____ joint.
a. humeroulnar joint, hinged
c. humeroradial joint, hinged
b. humeroulnar joint, pivot
d. humeroradial joint, piviot
4. The joint in Question #3 possesses _____ degree(s) of freedom.
a. 0
b. 1
c. 2
d. 3

and complete the motion of phase II.
a. the brachialis
c. a cocontraction of the above two
b. the anconeus
d. neither of the above two
9. The axis of rotation for elbow flexion/ extension of landing is close to _____.
a. a line passing through the radial and ulnar heads
b. a line passing through the medial and lateral epicondyles
c. the longitudinal axis of the ulna
d. the longitudinal axis of the radius
10 . This landing motion of Spiderman’s elbow joint follows a _____ path that is one kind
of _____ motion.
a. angular, rotary
b. angular, translatory
c. curvilinear, rotary
d. curvilinear, translatory
11. For an individual who raises his arm to shoulder abduction of 90 with the palm up and

is one kind of _____ kinematic chain motion since the distal end of the kinematic link
is _____.
a. open, free in the air
b. open, fixed
c. closed, free in the air
d. closed, fixed
