Document Summary
The digestive system can be divided into the alimentary canal and the accessory digestive organs. The alimentary canal is the muscular digestive tube that extends from the mouth to the anus, and it consists of the mouth, pharynx, esophagus, stomach, small intestine, large intestine, and anus. The accessory digestive organs consist of the teeth, tongue, gallbladder, salivary glands, liver, and pancreas. Structures associated with the oral cavity: the mouth or oral cavity is a mucosa-lined cavity. The mouth is divided into the vestibule (region in front of teeth) and the oral cavity proper (region of mouth that lies internal to the teeth). The hard palate and soft palate form the roof of the mouth. The uvula is attached to the soft palate and it rises during swallowing to close off the nasopharynx. Laterally, the soft palate is anchored to the tongue by the palatoglossal arches and to the wall of the oropharynx by the palatopharyngeal arches.
