Hearing And Equilibrium Flashcards
___, like vision, is considered to be one of the special senses.
Hearing
, the ability to detect a range of sound frequencies (pitches) and intensities (volumes), is only one of the senses mediated by the ear apparatus.
Hearing
Two types of equilibrium are also mediated by ear receptors.
Static
Dynamic
allows you to determine your position relative to a center of gravity.
In other words, it tells you whether you are right side up, upside down, or something in between.
static equilibrium
Your sense of ____ gives information regarding the speed and direction of your body’s motion.
kinetic (dynamic) equilibrium
refers to a blocking of sound waves as they are conducted through the external and middle ear to the sensory areas of the inner ear (the conduction pathway).
Conduction impairment
implies insensitivity to sound because of inherited or acquired nerve damage. The two hearing tests described are often used in clinical settings to screen patients with suspected hearing impairments.
- rinne test
- Weber test
Nerve impairment
What test?
Strike a tuning fork on the base of your palm, and place the handle against the subject’s mastoid process
Rinne test
What test?
Strike a tuning fork on the base of your palm, and place the handle against the middle of the forehead.
Weber test
The ___ demonstrates a subject’s ability to use information sensed by the utricle and saccule alone, without any help from the sense of vision.
a physical exam that assesses a person’s balance and neurological function
Romberg test
The ____ evaluates the function of the semicircular canals.
