midterm Flashcards
cranial nerves that play a role in eating
originate in the brain stem
CN I, V, VII, IX, X, XII
CN I
olafactory smell
chewing, movements of the lower jaw, movement of the palatal elevators, respnsible for sucking, initiates the swallow, tastes, facial expressoins, signals to the salivary glads.
trigeminal cnv
provides information to the back of the tongue, bitter tastes, muscles used in swallowing fibers to the salivary glands.
glossopharyngeal cn ix
motor and sensory connections of the pharynx, larynx, esophagus and the heart. provides contributions to respiration, blood pressure, heart rate.
vagus nerve cnx
assists in the contraction of tongue assists in bolus preparation, sucking and swallowing.
hypoglossal nerve: cnxii
seeing and smelling food, opening the mouth for the food to enter, biting, chewing, preparing and organizing the bolus.
ORAL prep phase
oral STAGE
bolus formation and cohesion continues, actively propels the bolus posteriorly to the back of the mouth
pharyngeal
nasal and laryngeal structures do their job of valving these openings so that food does not enter the airway.
the swallow reflex is triggered
the bolus moves through the pharynx
the bolus enters the esophagus.
esophageal
movement of bolus through the esophagus into the stomach
the UES relaxes
hyoid bone elevates
the UES closes immediately
gravity peristalsis, and changes in pressure move the food.
the LES relaxes and opens
food enters the stomach
the LES closes immediately.
o months- newporn”post term” the mother’s placenta helps the baby____ while it is growing in the womb
“breathe”
at birth the baby’s lungs are ____.
filled with fluid, they are not inflated.
baby takes its first breath within about _____ seconds after delivery.
10 seconds.
the babys first breath sounds like a gasp as the newborn’s CNS
CNS reacts to sudden change in temperature and environment.
after the first breath a number of changes occur in the infant’s lungs and circulatory system.
- increased oxygen in the lungs causes a decrease in blood flow resistance to the lungs
blood flow resistance of the baby’s blood vessels also increases
fluid drains4fluid is absorbed from the respiratory system
llungs inflate and begin working on their own.
when the lungs inflat and begin working on their own they move oxygen____ and cardon dioxide is____
oxygen to the blood stream (inhalation)
removing carbon dioxide by breathing out (exhalation.
physiological flexion
the bably recoil of flexed limbs when extended.
at rest the full-term baby is in a flexed position like____ (physiological flexion)
running
psysiological flexion provides___
stability for early posture and random movements.
amount of flexion is:
indivudual and depends on the size of the baby, the size of the mothers uterus, and the babys passive tone.
in physiological flexion. the babies posture is more flexed in____ and less flexed in___.
more flexed in prone (belly) less flexed in supine (back)
movement in 0-months new born post term is not random (t/f)
flase new born movements are random.
newborn 0 months “post term” movements are a continuation of movements that____
movements that occured in utero.
movements are individualized in new born’s 0 months “post term” (t/f)
true.
newborn’s movements vary with____ and ____
position and arousal.
a newborns movements increase when the baby is
crying, hungry or cold.
a newborns movements decrease when
they are tired or sleeping.
new born movements can be jerky and tremulus (t/f)
true
movements are ____ for baby to begin active ____
“practice for baby to begin active movements
six types of movements for baby
progressive, symmetrical, asymmetrical tonic neck reflex (ATNR), facial movements, isolated movements.
newborn progressive movements are
rhymic alternating flexion-extension movements of the limbs.
newborn progression movements involves____ (these body parts)
upper or lower limbs, can be one, or two, or three or all four limbs.
newborn symmetrical movements
quick, brief movements of the head, trunk, and limbs into flexion. the hands are closed.
newborn symmetrical movements some babies move into ______ and then quickly into ____
move into extension and then quickly into flexion.
newborn 0 month movements Asymmetrical tonick neck reflex (ATNR)
head turns to one side. arm and leg of opposite side flex.
newborn 0 months facial movements
grimaces, smiles, eyelids, tongue, sucking.
