A biological system that enables us to know where our bodies
are in the environment and to maintain a desired position. Normal balance depends
on information from the inner ear, other senses (such as sight and touch) and muscle
movement.
Our sense of balance is specifically regulated by a complex interaction between
the following parts of the nervous system:
The inner ears (also called the labyrinth) monitor the directions of motion,
such as turning or forward-backward, side-to-side, and up-and-down motions.
The eyes observe where the body is in space (i.e., upside down, right side
up, etc.) and also the directions of motion.
Skin pressure receptors such as those located in the feet and seat sense
what part of the body is down and touching the ground.
Muscle and joint sensory receptors report what parts of the body are moving.
The central nervous system (the brain and spinal cord) processes all the
bits of information from the four other systems to make some coordinated sense
out of it all.
