The flashcards below were created by user lcunrod7 on FreezingBlue Flashcards. What would you like to do?


  1. what are the structures of the oral cavity
    cheeks, lips, hard and soft palate, uvula, labial frenulum, fauces
  2. what oral structure has fat pads and buccinator muscle
    cheeks
  3. what oral structure is continuous with cheeks, lost of sensory (touch receptors)
    lips (labia)
  4. what oral structure has tongue compresses food against to start swallowing process, contains bone
    hard palate
  5. what oral structure is musclar part of mouth
    soft palate
  6. what oral structure is posterior margin of soft palate and prevents food from entering pharynx prematurely
    uvula
  7. what oral structure attaches lower lip to jaw
    labial frenulum
  8. what oral structure is connection between oral cavity and oropharynx
    fauces
  9. what secrete saliva into oral cavity and object in mouth can trigger salivary reflex
    salivary glands
  10. what are the three parts to the salivary gland
    sublingual, submandibular, parotid
  11. what part of the salivary gland is under the tounge
    sublingual
  12. what part of the salivary glad is in flood of mouth, secrete mix of buffers, mucins, salivary amylase (breaks down starch)
    submandibular
  13. what part of the salivary gland transports antibodies into saliva for protection against pathogens
    submandibular
  14. what part of the salivary gland is inferior to zygomatic arch
    parotid
  15. what part of the salivary gland secretes salivary amylase and drained by parotid duct
    parotid
  16. what manipulates materials inside mouth
    tongue
  17. what has glands the secrete mix of water, mucin, and lingual lipase (break down starch)
    tongue
  18. what surface contains lingual papillae; projections which contain taste buds (gustatory receptors)
    tongue
  19. what have 2 sets and are located in the mouth
    teeth
  20. what is the 1st set of teeth called, primary dentition
    deciduous
  21. what is the 2nd set of teeth called, secondary dentition
    permanent
  22. what are the four types of teeth
    incisors, cuspids, bicuspids, molars
  23. which teeth are clip and cut
    incisors
  24. what are the "canine" tearing teeth
    cuspids
  25. what are the crush and mash teeth
    bisucpids
  26. what are the crush and grind teeth
    molars
  27. what happens when food enters the digestive tract as a compact, moist mass (bolus)
    peristaisis
  28. what is smooth muscle in the muscular is extern propels material via peristaltic contractions
    peristalsis
  29. what is a wave of contraction moves bolus forward: bolus of food arrives in GI tract, circular muscle contract behind bolus, longitudinal muscle contract ahead of bolus, and contraction in circular layer moves bolus forward
    peristalsis
  30. what has most parts of the SI and some parts of the LI have cycles of contraction which serve to churn and fragments the bolus, mixing within intestinal secretions
    segmentation
  31. what is no set pattern, therefore there is no propulsion of the bolus forward in the tract
    segmentation
  32. what are the two parts of chewing
    mechanical and chemical digestion
  33. what part of chewing involves mastication, tearing grinding and mashing with teeth
    mechanical digestion
  34. what part of chewing involves salivary amylase -carbs and lingual lipase - fats
    chemical digestion
  35. what is when both types of digestion results in the production of the bolus
    chewing
  36. what is initiated voluntary but proceeds automatically, can happen subconsciously
    swallowing
  37. what are the three phases of swallowing
    buccal phase, pharyngeal phase, esophageal phase
  38. what phase of swallowing is the compression of bolus against hard palate: food force into oropharynx
    buccal phase (voluntary)
  39. what phase of swallowing has tactile receptors on palate and uvula are stimulated
    pharyngeal phase
  40. what phase of swallowing is coordinated patter of muscle contraction by pharynx and by signals initiated by medulla oblongata
    pharyngeal phase
  41. what phase of swallowing has bolus forced through pharynx into esophagus
    pharyngeal phase
  42. what phase of swallowing has peristaltic waves and contractions, takes about 9 seconds and liquids are faster, non-lubricated solids slower
    esophageal phase
