Balance is achieved and maintained by a complex set of sensorimotor control systems that include sensory input from vision (sight), proprioception (touch), and the vestibular system (motion, equilibrium, spatial orientation); integration of that sensory input; and motor output to the eye and body muscles.
Where is the sense of balance found in the body?
It is also essential to our sense of balance: the organ of balance (the vestibular system) is found inside the inner ear. It is made up of three semicircular canals and two otolith organs, known as the utricle and the saccule.
What part of the ear is responsible for balance?
Many structures in the inner ear, called the vestibular system together, send signals to the brain, helping you to align yourself and keep your balance. Two parts of the inner ear called the utricle and the saccule track the head’s angular motions (from side to side and up and down), and sense gravity, too.
Which part of the body helps us to balance our body?
The inner ear is the part that helps us to balance our body. The inner ear is involved in both the functions of hearing and balancing. The inner ear is enclosed within the temporal bone of the skull.
How does the brain maintain balance?
Maintaining balance depends on information received by the brain from the eyes, muscles and joints, and vestibular organs in the inner ear.
What maintains our sense of balance?
Good balance depends on: Correct sensory information from your eyes (visual system), muscles, tendons, and joints (proprioceptive input), and the balance organs in the inner ear (vestibular system). 2. The brain stem making sense of all this sensory information in combination with other parts of the brain.
Which system helps us maintain a sense of balance and equilibrium?
The vestibular system is the sensory apparatus of the inner ear that helps the body maintain its postural equilibrium. The information furnished by the vestibular system is also essential for coordinating the position of the head and the movement of the eyes.
Which part of the body controls balance?
It is also essential to our sense of balance: the organ of balance (the vestibular system) is found inside the inner ear. It is made up of three semicircular canals and two otolith organs, known as the utricle and the saccule. The semicircular canals and the otolith organs are filled with fluid.

Homeostasis: a Definition Homeostasis, as currently defined, is a self-regulating process by which biological systems maintain stability while adjusting to changing external conditions.
Which system of the body is responsible for elimination of wastes and regulating the volume and composition of blood?
Your urinary system, also called the renal system or urinary tract, removes waste from your blood in the form of urine. It also helps regulate your blood volume and pressure, and controls the level of chemicals and salts (electrolytes) in your body's cells and blood.
What is the vestibular system?
The vestibular system helps you perceive which way you are spinning on a merry-go-round, which way you are tilting on a boat and simply, which way is up. These perceptions contribute to your sense of equilibrium (state of physical balance) and keep you safe from falling. Next time you are walking around or enjoying a boat ride, ...
What are the functions of the vestibular system?
In action, our vestibular system has three main functions: gaze stability, gait stability, and spatial orientation. We checked in with Dr. Steven Rauch, Director of the Vestibular Division at Mass Eye and Ear, to learn more about these functions and why they are important.
What is the 6th sense?
Often referred to as our “sixth sense,” balance relies on input from several areas of the body to keep you from falling — the inner ear, the eyes, the muscles and joints in your leg and spine.
Which sense system has only one input?
Each of your other senses has only one input: You see with your eyes, smell with your nose, taste with your tongue, etc. The vestibular system , however, has several sensory inputs: Balance organs of your inner ear (five on each side), visual inputs and inputs from the muscles and joints in your legs and spine.
How to keep your feet upright?
Maintaining an upright stance on one or two feet requires constant communication between the sensory signals from the feet, legs and spine to the brain. These muscle signals are sent to the brain and then back down to make adjustments in your body that will keep you upright and stable in a variety of activities—like keeping you steady while running.
What are the factors that affect the sense of balance?
Injury, disease, certain drugs, or the aging process can affect one or more of these components. In addition to the contribution of sensory information, there may also be psychological factors that impair our sense of balance.
What is balance?
Balance is the ability to maintain the body’s center of mass over its base of support. 1 A properly functioning balance system allows humans to see clearly while moving, identify orientation with respect to gravity, determine direction and speed of movement, and make automatic postural adjustments to maintain posture and stability in various conditions and activities.
What is the sensory input of the skin, muscles, and joints?
Input from the muscles and joints. Proprioceptive information from the skin, muscles, and joints involves sensory receptors that are sensitive to stretch or pressure in the surrounding tissues. For example, increased pressure is felt in the front part of the soles of the feet when a standing person leans forward.
Why are rods and cones important?
at night time). Cones help with color vision, and the finer details of our world. When light strikes the rods and cones, they send impulses to the brain that provide visual cues identifying how a person is oriented relative to other objects.
What is the complexity of the human balance system?
The complexity of the human balance system creates challenges in diagnosing and treating the underlying cause of imbalance. The crucial integration of information obtained through the vestibular, visual, and proprioceptive systems means that disorders affecting an individual system can markedly disrupt a person’s normal sense of balance.
What are the symptoms of impaired balance?
Impaired balance can be accompanied by other symptoms such as dizziness, vertigo, vision problems, nausea, fatigue, and concentration difficulties.
What is the function of the brain stem in the body?
As sensory integration takes place, the brain stem transmits impulses to the muscles that control movements of the eyes, head and neck, trunk, and legs, thus allowing a person to both maintain balance and have clear vision while moving.
What part of the ear is responsible for keeping your balance?
Many structures in the inner ear, called the vestibular system together, send signals to the brain, helping you to align yourself and keep your balance. Two parts of the inner ear called the utricle and the saccule track the head’s angular motions (from side to side and up and down), and sense gravity, too. Certain structures that shape loops, which contain fluid, track the head’s rotation.
Why are standard balance tests used in the study?
Standard balance tests were used in the study to measure the equilibrium in participants while they were wearing hearing aids, and while they weren’t. The study concluded that sound information coming through their hearing aids tended to be used by the participants as sensory reference points or landmarks to help maintain equilibrium.
How do hearing aids help you in your life?
Hearing aids can improve equilibrium by allowing you to hear many more sounds in the environment. The brain can get a better spatial vision and understand auditory signals. Compared to visual information, which can only be gleaned in front of you, sounds enter you from all directions, and your sense of hearing is crucial to your understanding of your surroundings.
Why is it important to have hearing aids?
Hearing explicitly allows the surroundings to be better understood , and you are less likely to be taken by surprise by something or someone around you. This awareness also improves your balance, and those with hearing aids have far fewer trips, slips drops, and accidents compared to those with untreated hearing loss.

How does a person with no equilibrium disorder keep a sense of balance? This process relies on teamwork between the sensory organs and the brain.
Why are ears important?
Finally, the ears aren’t just important for hearing; they assist in the balance as well.
What organs are connected to the body?
Let’s take first the skin, the joints, and the muscles. All body parts are connected with these organs, using the nerves to collect overall knowledge about many things, ranging from temperature, heat, and humidity to elevation changes. The brain gathers information from the body about the world, and then sends signals back to the body to tell them how to move and react.
Which part of the body is responsible for maintaining the balance and equilibrium of the body?
the vestibule (has the saccule and utricle) that connects the semicircular canals to the cochlea. The semicircular canals and the vestibule of the inner ear together help to maintain the balance and equilibrium of the body.
