ABSTRACT
Human body consist of many systems. One of them is skeletal system. One of member of
skeletal system is bones. The activity’s purpose is to identify bone’s anatomy.
The main activity is observe the replica of human skeleton. The observer observe the
object and identify the name with anatomy map.
Human has 206 bones. Basically human skeleton divided into two major groups they are
axial part and appendicular part. The axial’s member are skull. Backbones, thoracic cage.
Meanwhile the member of appendicular are bones which arrange hands and foot and bones
whoch connect movements bones with the axial skeleton. The difficulty of this activity is the
observer should compare the replica of skeleton with the map properly.
Keywords: appendicular, axial bones, backbones, skull, pelvis.

ABSTRACT
The purpose of this experiments is to understand the definition of reflex. Basically reflex
is a rapid movement due to unconscious impulse given to someone. The impulse proceed by the
spinal cord, not the brain.
The principles of the experiments is the subject given impulse in 10 points they are knee,
Achilles, bicep, triceps, and cornea. Each point applied on the left and right side. The impulse
given to subject when the subject didn’t giving attention to her partner so they didn’t realize
when the impulse comes.
The result of the experiment is the four subjects shows reflex movement. The difficulty
of this experiment is detecting the movement since its fast and quick.
