Mr Epiglottis

Pejam celik-pejam celik dah hampir 4 bulan saya belajar anatomy..dah banyak topik yang dah 'cover'... dari bones, ke muscle, ke nerves, ke vessels, ke skull, dan hari ni lecture digestive system..ataupun sistem pencernaan.

Hari ni lecture anatomy tidak seperti biasa, prof Halata membuka fikiran segelintir muslim yang 'perasan' hikmah sunnah Rasulullah.

'The epiglottis guards the entrance of the glottis, the opening between the vocal folds. It is normally pointed upward during breathing with its underside functioning as part of the pharynx, but during swallowing, elevation of thehyoid bone, draws the larynx upward; as a result, the epiglottis folds down to a more horizontal position, with its upper side functioning as part of the pharynx. In this manner it prevents food from going into the trachea and instead directs it to the esophagus, which is more posterior.' kata profesor Halata.

Dan dia menokok,

'that's why we do not talk while eating, to avoid the food from entering the trachea (organ pernafasan)' dan segelintir pelajar yang ingat itu adalah lawak gelak terkulat-kulat.
