Document Summary
Anklyoglossia- condition where you have very short frenulum so it restricts the tongue"s range of motion. Language disorder: cannot generate language information as effective and fast- caused by damage in brain. The biological foundations of speech and language: the vocal mechanism, the articulatory mechanism, the nervous system. Respiratory system structural support of the respiratory system: Muscles of inhalation: (make the space larger) Diaphragm (below the 2 lungs, dome shaped, when it contracts, it shorts, and when it relaxes it returns to it"s original position). When air molecules pour into the lung, the diaphragm shortens. Muscles of exhalation: (make space smaller, pushing all the air molecules out) Muscles in the thorax respiration is involuntary because it"s a natural reflex, but also voluntary because you can control it. Als- lose control over voluntary movement (like parts of your body) Ex: tony judt: diagnosed with als in 2008. Tidal breathing: breathing in & out without thinking.
