Proprioceptive Sensations •
•
Sensations relating to the physical state of the body Static position sense vs. Rate of movement sense
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
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.
Cues Important in Spatial Orientation •
Kinesthetic cues –
Joint receptors of the neck
–
Pressure sensations from footpads (Baroreceptors)
–
Muscle spindles
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
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
