معنى التجويف هو الفراغ

تجويف الفم معناه الفم من داخل «عند فتح الفم أمام المرآة سوف تشاهدين اللسان والاسنان والاضراس وكذلك الفك علوي والفك سُفلي...

يتكون تجويف الفم من..

1_اللسان «عند فتح الفم نرى ان اللسان عبارة عن قطعة لحم عضلة مرنة وتكون مرنة لطرواتها وشكلها بيضوي قابلة للانقباض والانبساط»

يعد اللسان من هم أعضاء النطق لأنه عضو متحرك عكس بعض أعضاء النطق تكون ثابتة..

_يخرج منه بمساعدة واشتراك طرف آخر 18 حرف فيكون اللسان طرف مخرج يشترك مع طرف آخر ليخرج صوت الحرف

أي اللسان عضو وطرف متحرك يذهب مع عضو ثابت ليخرج صوت الحرف...

مثال حرف الذال يكون مخرجه طرف اللسان + أطراف الثنايا العليا «الثنايا يقصد بها الاسنان»

والاسنان بطبيعتها عضو ثابت يذهب اللسان المتحرك الى طرفها العلوي الثابت لاخراج صوت حرف الذال

طرف اللسان يترفع الى الاعلى عند أطراف الثنايا ينطبقان معًا ويخرجان حرف الذال
