What sense is responsible for balance and head position?
The vestibular system
The vestibular system is a sensory system that is responsible for providing our brain with information about motion, head position, and spatial orientation; it also is involved with motor functions that allow us to keep our balance, stabilize our head and body during movement, and maintain posture.
What is the function of analytical balance?
Analytical balances are highly sensitive lab instruments designed to accurately measure mass. Their readability has a range between 0.1mg – 0.01mg. Analytical balances have a draft shield or weighing chamber to prevent the very small samples from being affected by air currents.
Which part of brain affects balance?
Cerebellum
Cerebellum: Sensing how to balance.
What part of brain affects balance?
What are the parts of analytical balance and their functions?
Parts of the Analytical Balance
- Balance plate (pan) used as a container to put the sample of material to be measured in mass.
- Weights. serves as a tool to calibrate analytical scales.
- Water pass. a tool used to determine the position of the balance plate.
- ‘Re-zero’ or ‘Tare’ button.
- ‘Mode’ button.
What causes drift in a balance?
Drift is caused by the scale or balances recording changes in weight resulting from environmental factors that affect the sample’s mass.
What part of the brain controls vertigo?
Central vertigo is due to a problem in the brain, usually in the brain stem or the back part of the brain (cerebellum).
How does the vestibular system control balance?
Vestibular system: Balance organs in the inner ear tell the brain about the movements and position of your head. There is a set of three tubes (semi-circular canals) in each ear, and these sense when you move your head around and help keep your vision clear.
What are the major types of analytical balance?
Four Types of Laboratory Balances
- Semi Micro, Micro & Ultra Micro Balances. For weighing the smallest amounts, ultra micro and micro balances are selected.
- Analytical Balance.
- Top-Loading and Precision Balance.
- Triple-Beam Balances.
- History in Equal Arm Balances.

What can affect balance readings?
When using a lab balance, there are a variety of factors that can ultimately affect how accurate your readings will be, including:
- The type of balance you’re using.
- Calibration of the equipment.
- The placement of the unit.
- Proximity to air draft sources.
- The ambient environment.
How do you know the balance is level?
Operating an analytical balance Check the balance is level using the level indicator (see Figure 1). If the bubble is not in the centre adjust the level, normally by twisting the feet, until the bubble is in the centre of the inner circle. Check that the balance is on and that the door is closed.
What affects balance in the brain?
The vestibular system is one of the sensory systems that provides your brain with information about balance, motion, and the location of your head and body in relation to your surroundings. There are three loops in your inner ear, called semicircular canals. The first canal senses up-and-down movement.
What part of the brain is responsible for balance?
And while your balance system engages several parts of your brain, the main part of the brain that controls balance is the cerebellum. Science American explains that the cerebellum – sometimes quaintly known as the “little brain“ – is located at the very back of your skull.
What is the torsion balance used to measure?
torsion balance, device used to measure the gravitational acceleration at the Earth’s surface. Other such devices, using different methods to obtain the same result, are pendulums and gravimeters. The torsion balance consists essentially of two small masses at different elevations that are supported at opposite ends of a beam.
Why is there no torque in torsion balance experiments?
There is no torque unless there is a non-zero angle between the forces, so torsion balance experiments are null experiments that detect any non-parallelism of the forces on the test bodies.
Can torsion fields explain the effects of consciousness?
According to A. Akimov, torsion fields coupled with the standard electric, magnetic, and gravity fields should offer a unified field theory that will extend the realm of science to include the effects of consciousness.
