-
what are the structures of the oral cavity
cheeks, lips, hard and soft palate, uvula, labial frenulum, fauces
-
what oral structure has fat pads and buccinator muscle
cheeks
-
what oral structure is continuous with cheeks, lost of sensory (touch receptors)
lips (labia)
-
what oral structure has tongue compresses food against to start swallowing process, contains bone
hard palate
-
what oral structure is musclar part of mouth
soft palate
-
what oral structure is posterior margin of soft palate and prevents food from entering pharynx prematurely
uvula
-
what oral structure attaches lower lip to jaw
labial frenulum
-
what oral structure is connection between oral cavity and oropharynx
fauces
-
what secrete saliva into oral cavity and object in mouth can trigger salivary reflex
salivary glands
-
what are the three parts to the salivary gland
sublingual, submandibular, parotid
-
what part of the salivary gland is under the tounge
sublingual
-
what part of the salivary glad is in flood of mouth, secrete mix of buffers, mucins, salivary amylase (breaks down starch)
submandibular
-
what part of the salivary gland transports antibodies into saliva for protection against pathogens
submandibular
-
what part of the salivary gland is inferior to zygomatic arch
parotid
-
what part of the salivary gland secretes salivary amylase and drained by parotid duct
parotid
-
what manipulates materials inside mouth
tongue
-
what has glands the secrete mix of water, mucin, and lingual lipase (break down starch)
tongue
-
what surface contains lingual papillae; projections which contain taste buds (gustatory receptors)
tongue
-
what have 2 sets and are located in the mouth
teeth
-
what is the 1st set of teeth called, primary dentition
deciduous
-
what is the 2nd set of teeth called, secondary dentition
permanent
-
what are the four types of teeth
incisors, cuspids, bicuspids, molars
-
which teeth are clip and cut
incisors
-
what are the "canine" tearing teeth
cuspids
-
what are the crush and mash teeth
bisucpids
-
what are the crush and grind teeth
molars
-
what happens when food enters the digestive tract as a compact, moist mass (bolus)
peristaisis
-
what is smooth muscle in the muscular is extern propels material via peristaltic contractions
peristalsis
-
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
-
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
-
what is no set pattern, therefore there is no propulsion of the bolus forward in the tract
segmentation
-
what are the two parts of chewing
mechanical and chemical digestion
-
what part of chewing involves mastication, tearing grinding and mashing with teeth
mechanical digestion
-
what part of chewing involves salivary amylase -carbs and lingual lipase - fats
chemical digestion
-
what is when both types of digestion results in the production of the bolus
chewing
-
what is initiated voluntary but proceeds automatically, can happen subconsciously
swallowing
-
what are the three phases of swallowing
buccal phase, pharyngeal phase, esophageal phase
-
what phase of swallowing is the compression of bolus against hard palate: food force into oropharynx
buccal phase (voluntary)
-
what phase of swallowing has tactile receptors on palate and uvula are stimulated
pharyngeal phase
-
what phase of swallowing is coordinated patter of muscle contraction by pharynx and by signals initiated by medulla oblongata
pharyngeal phase
-
what phase of swallowing has bolus forced through pharynx into esophagus
pharyngeal phase
-
what phase of swallowing has peristaltic waves and contractions, takes about 9 seconds and liquids are faster, non-lubricated solids slower
esophageal phase
