من ألغاز الطبيعة حولنا اللسان الخشن !!!!!!!!

Coarse tongue in predators
 
الذين يربون القطط يتعرضون للعقها بين الحين و الاخر لتعبر عن رغبتها في الماء أو الغذاء …!! و حينئذ يلاحظون ان لسان القطط خشن و الواقع ان هذه الصفة تعم جميع الكائنات الحية من فصيلة القطط كالأسود و النمور و حيوانات برية أخري كثيرة .

هذه الخشونة سببها وجود جزئيات من الجلد الخشن بين خلايا التذوق علي سطح اللسان .. أما حكمة الخالق ( عز و جل ) في نخصيص تلك الحيوانات بها فهي تمكينها من الاستفادة الي أقصي قدر ممكن بكل ما تحصل عليه من طعام .
فاللسان الخشن يساعد الحيوانات البرية كالأسود و النمور علي لعق كل ما يتبقي علي العظام من جزيئات اللحم الدقيقة , و لخشونة اللسان فائدة أخري فهي تمكنها من تنظيف فرائها و صغارها حيث تستعمله كالفرشاة و المشط فضلا عن أنه يسهل عملية لعق الطعام و الشراب .
