what is vertigo ?

Answer 1

Vertigo is usually caused from a balance disorder.

A balance disorder is a disturbance that causes an individual to feel unsteady, giddy, woozy, or have a sensation of movement, spinning, or floating. An organ in our inner ear, the labyrinth, is an important part of our vestibular (balance) system. The labyrinth interacts with other systems in the body, such as the visual (eyes) and skeletal (bones and joints) systems, to maintain the body's position. These systems, along with the brain and the nervous system, can be the source of balance problems.

Three structures of the labyrinth, the semicircular canals, let us know when we are in a rotary (circular) motion. The semicircular canals, the superior, posterior, and horizontal, are fluid-filled. Motion of the fluid tells us if we are moving. The semicircular canals and the visual and skeletal systems have specific functions that determine an individual's orientation. The vestibule is the region of the inner ear where the semicircular canals converge, close to the cochlea (the hearing organ). The vestibular system works with the visual system to keep objects in focus when the head is moving. Joint and muscle receptors also are important in maintaining balance. The brain receives, interprets, and processes the information from these systems that control our balance.

Answer 2

Vertigo, or dizziness, is a symptom, not a disease. The term vertigo refers to the sensation of spinning or whirling that occurs as a result of a disturbance in balance (equilibrium). It also may be used to describe feelings of dizziness, lightheadedness, faintness, and unsteadiness. The sensation of movement is called subjective vertigo and the perception of movement in surrounding objects is called objective vertigo.

Vertigo usually occurs as a result of a disorder in the vestibular system (i.e., structures of the inner ear, the vestibular nerve, brainstem, and cerebellum). The vestibular system is responsible for integrating sensory stimuli and movement and for keeping objects in visual focus as the body moves.

When the head moves, signals are transmitted to the labyrinth, which is an apparatus in the inner ear that is made up of three semicircular canals surrounded by fluid. The labyrinth then transmits movement information to the vestibular nerve and the vestibular nerve carries the information to the brainstem and cerebellum (areas of the brain that control coordination, balance, movement, blood pressure, and consciousness). There are a number of different causes for dizzy spells.

Answer 3

Best example I can think of vertigo is with skiing on Mt. hood. When there is a complete whiteout from a snow storm, and you can't see anything but white. It made me feel dizzy, I couldn't tell if I was moving or if I was stopped. Pretty scary.

Answer 4

Vertigo is a disorder that causes dizziness. check out this website for a clear explanation:

Answer 5

Vertigo is a movie by alfred Hitchcock.

Answer 6

it is basically dizziness caused by an imbalance of fluids in the semicircular canals of the inner ear. This can be caused by infection, medications, too much motion, disease, impact to the head, etc. If you experience this for a period of time, you should definitely see a doctor. This is often accompanied by tinnitus or a ringing in the ears.

Answer 7

It's that and it is also a movie by Alfred Hitchcock starring Cary Grant!

Answer 8

It is when the the balance detectors (equilibrium) in your ears don't match with what your eyes are tellling you.

Answer 9

AN IMBALLANCE IN THE MIDDLE EAR THAT CAUSES DIZZY NESS

Answer 10

Is when you like go on something really high, and you feel nauseous, and scared, and stuff. (AFRAID OF HEIGHTS)
