Document Summary

Anatomical components of: oral cavity, palate, tongue, teeth, salivary glands, pharynx. Smell the stuff first, passes through thalamus and brings up memories and tells us to eat (?) All senses are somehow involved in eating (crunch, smell, soft ) Phases and stages of digestion today focus on oral phase: oral phase: ingestion and mechanical processions, gastric phase: digestion and secretion of juices, intestinal phase: absorption, assimilation, and elimination. Oral (buccal) cavity the mouth: oral vestibule, oral cavity proper, hard palate, soft palate, uvula, tonsils, tongue, the pharynx, accessory organs of the oral cavity, teeth, salivary glands. Functions: food ingestion, mechanical processing, chemical digestion, speech (articulation and vocalization), breathing, somatosensory sensation, immunity (ring of lymphatic tissue in oral cavity first barrier to infections) Anterior boundaries: lips or labia, labial frenulum, teeth, tip of tongue. Lateral boundaries: cheeks, teeth & gingiva, jaws. Superior boundaries (roof): hard and soft palates. Posterior boundaries: uvula, palatine tonsil, lingual tonsil, roof of tongue, fauces.
