Structures of the vestibular system?
The vestibular system detects angular and linear acceleration. This is made possible by two related parts of the peripheral vestibular system: 1) the otoliths (utricle and saccule), which are sensitive to accelerative forces in a single plane (e.g. gravity); and 2) the semicircular canals - of which there are three at roughly orthogonal planes to each other - that are sensitive to accelerative forces in a circular plane (e.g. if you were to sit in the middle of a merry-go-round). There are peripheral vestibular organs located on each side of the head behind the ear. Technically they are referred to 'inner ear organs'. The primary function of the vestibular system (collectively: the peripheral organs + VIII cranial nerve + brainstem vestibular nuclei) is to detect accelerative forces and generate nerve impulses to the brain for integration with other senses and motor control. For simplicity we refer to the vestibular system as providing 'balance-sense' - however, 'balance' is how the brain interprets the signals. The organs themselves sense acceleration. The brain needs these signals in order to stabilize the eye muscles during head movements, allowing us to maintain gaze on a target. Vestibular signals are also used for axial-muscle motor control which allow us to maintain a center of gravity whilst upright. Blood-pressure regulation is also influenced by the vestibular system during changes in posture from a supine to an upright position. Vestibular signals are extensively integrated throughout the brain. In fact, they can even influence mood, the ability to think (calculate), and our memory systems - particularly spatial memory (i.e., 'cognitive mapping' of our environment). Interestingly, mood-centers of the brain also feed back into the vestibular system, which is why people afraid of heights (acute anxiety) may get a sudden attack of vertigo (perceived movement of the world, in the absence of real movement) if high up on the top of a building, say. The opposite is also true - people with balance disorders often develop DSM-IV psychiatric comorbidities, like agoraphobia, generalised anxiety disorder, and depression. The same people also have excruciating difficulty remembering where they are in relation to where they want to go - and an unfortunate consequence of this is that they often get lost. Even in familiar places. In terms of evolution, the vestibular system is the oldest sensory system. This may explain the intricate dependency the brain has for information about bodily acceleration.
What is Vestibular nerve sectioning?
The surgeon enters the internal canal of the ear and separates the nerve bundles governing hearing from the nerve bundles that govern the sense of balance, in order to control the patient's vertigo without sacrificing hearing
What is a primary protein structure formed by?
the order of its amino acids
The steps of mitosis listed in proper order are?
prophase,metaphase,anaphase,telophase
How does an organelles structure affect it's function?
It has to be made properly in order to do what it's supposed to do.
What is the proper order for the vestibular perineal structures from anterior to posterior?
For a woman : Clitoris, urethral opening, vaginal orifice, anus
What is data structure in c?
arrang the data in proper order in the program or in the memory is called a data structure, lke arranging the names of diff students in alphabetical order.
What is structure key in protein molecules?
We can consider the peptide bond as the key structure of all proteins. The peptide bond gives to the protein the proper configuration in order to its biological activity or significance.
What term means structure?
Structure means an imposed order, versus chaos.
What is the difference between a matrix structure and a organisational structure?
the difference between an organisational structure and a matrix structure is that a matrix structure is a combined structure whereas an organisational structure is in a vertical order and has different levels.
In what kind of text structure are events told in the order they happened?
Events are typically told in chronological order in a text structure called sequential or chronological structure. This structure presents information in the same order that the events occurred, allowing readers to follow a timeline of events.
