10. Cues Important in Spatial Orientation
• Visual Cues
– Slight linear or rotational movement of the
body, instantaneously shifts the visual images of
the retina, and this information is relayed to the
equilibrium center
11. Cues Important in Spatial Orientation
• Vestibular cues
– Proper orientation of our head, limbs, and entire
body is achieved by reflex signals originating
from the vestibular apparatus.
12. Cues Important in Spatial Orientation
• Kinesthetic cues
– Joint receptors of the neck
– Pressure sensations from footpads (Baroreceptors)
– Muscle spindles
13. Cues Important in Spatial Orientation
• Exteroreceptive
information
– Important when a person
is in motion
– Air pressure against the
front of the body signals
that a force is opposing
the body in a direction
different from that
caused by the
gravitational pull; as a
result, the person leans
forward to oppose this
14. Corrective motions for balance
The body moves to a position
such that its center of gravity
falls on the same longitudinal
axis as that of its foundation
