,◉ Parasympathetic stimulation of the salivary glands causes....
Answer: Continuous secretion of saliva and keeps the mucous
membrane moist and lubricated
◉ Sympathetic stimulation of the salivary glands causes.... Answer:
Salivary glands to stop secreting saliva to conserve water, causes
dryness of mouth.

skeletal muscle covered in mucous membrane, and with the
associated muscles forms the floor of the oral cavity

of food from the esophagus into the stomach
◉ Deglutition. Answer: Swallowing, involves the mouth, pharynx,
and esophagus, has 3 stages
◉ Voluntary stage (Deglutition). Answer: 1st, Bolus is passed into
the oropharynx
◉ Pharyngeal stage (Deglutition). Answer: 2nd, involuntary passage
of the bolus through the pharynx into the esophagus
◉ Esophageal stage (Deglutition). Answer: 3rd, involuntary passage
of the bolus through the esophagus into the stomach
◉ Peristalsis. Answer: Coordinated contractions and relaxations of
the circular and longitudinal layers of the muscularis
