Tracheomalacia may involve hypotonia of the trachealis muscle. [6]The trachealis muscle may become stiffer during ageing, which makes the whole trachea less elastic. [7]In infants, the insertion of an oesophagogastroduodenoscope into the oesophagus may compress the trachealis muscle, and narrow the trachea. [8]
The trachealis muscle connects the ends of the incomplete rings and runs along the back wall of the trachea. [3] Also adventitia, which is the outermost layer of connective tissue that surrounds the hyaline cartilage, contributes to the trachea's ability to bend and stretch with movement. [4]
Tracheomalacia occurs when the walls of the trachea collapse. This can happen because the walls of the windpipe are weak, or it can happen because something is pressing on it. This may include hypotonia of the trachealis muscle. [3] The whole windpipe can be affected, or only a short piece of it.
Psychophysiology measures exist in multiple domains; reports, electrophysiological studies, studies in neurochemistry, neuroimaging and behavioral methods. [5] Evaluative reports involve participant introspection and self-ratings of internal psychological states or physiological sensations, such as self-report of arousal levels on the self-assessment manikin, [6] or measures of interoceptive ...
Stevens' power law is an empirical relationship in psychophysics between an increased intensity or strength in a physical stimulus and the perceived magnitude increase in the sensation created by the stimulus.
Even muscles not being in a direct connection towards a certain joint can fulfill a stabilising function for that very joint. For a clear specification of any muscles function it is necessary to measure precisely muscular function of not directly involved muscles within certain movements via elktromyografia .
In biochemistry and pharmacology, the Hill equation refers to two closely related equations, one of which describes the response (the physiological output of the system, such as muscle contraction) to Drug or Toxin, as a function of the drug's concentration. [12] The Hill equation is important in the construction of dose-response curves.
An example of table-turning in 19th century France. A circle of participants press their hands against a table, and the ideomotor effect causes the table to tilt in such a way as to produce a written message, in a manner similar to a ouija board. [1]
