lining is short in healthy individuals. However‚ it is increased in people with swallowing difficulty or in a supine position. The oesophageal lining is composed of stratified squamous epithelium which is relatively impermeable to drugs. The passage of food is lubricated with saliva and mucin coating the oesophagus epithelium. The pH of the oesophagus is about pH6-7‚ which is equivalent to the pH of the salvia[19]‚ while the pH of the stomach is between 1.5 to 2 [20]. A swallowing action is a voluntary

Epithelium is derived from the oral ectoderm‚ while the only source of mesenchyme able to sustain tooth development is derived from multipotential stem cells called cranial neural crest cells (NCCs) (Jheon et al.‚ 2013; Miletich‚ 2004). Some cranial NCCs located

Gastric mucosal lies over the epithelium. The secretion of mucus and bicarbonate serve as the first line of defense in the stomach and work to maintain a normal pH. Mucus and bicarbonate both protect the stomach against acid‚ while gastro-mucosal prostaglandins increase this barrier. Its important that the stomach receives a rich blood supply to keep its integrity. When a break in the mucosal lining occurs hydrochloric acid is able to reach the epithelium. When the epithelium is injured dysfunction of

sexual behavior greatly influences the incidence and prevalence of HPV infections.18 To develop infection‚ infectious particles must find their way to cells in the basal layer of skin. Usually this access is provided through breaks in the stratified epithelium as a result of micro-abrasions or micro-traumas.
