You are currently looking at your well-stocked fridge choosing which snack you will eat later, as you spend another night binge-watching series on Netflix. Which would be true about this situation?
about 1,000-1,500mL of saliva will be immediately released by your salivary glands causing "mouth watering"
the sight of all the food in your fridge would trigger your simple salivation reflex to activate and cause "mouth watering"
the sight of all the food in your fridge would trigger your acquired salivation reflex to activate and cause "mouth watering"
your sympathetic system will be activated and will instruct your salivary glands to produce more saliva causing "mouth watering"
Which of the following are true about what is depicted in this GIF
The soft palate and uvula moved upwards to close the oropharynx so food doesn't travel upwards
The glottis closes the epiglottis so that as you swallow, food doesn't travel to your respiratory system
This process is called mastication wherein bolus is passed from the oral cavity to the pharynx
The epiglottis closes the glottis so that as you swallow, food doesn't travel to your respiratory system
When a person is talking, which tongue muscles are at work?
Extrinsic muscles of the tongue
Intrinsic muscles of the tongue
Muscles of the tongue innervated by CN 7: facial
Muscles of the tongue innervated by CN 9: glossopharyngeal
Your baby brother currently got his first tooth ever! You know that:
It's normal since the first tooth usually erupts at 6 years old
It's most probably the lower central incisor that erupted
It's the start of the growth of his secondary set of teeth
By the age of 21, he'll have 20 teeth in total
Layer of the GIT that contains cells that are able to secrete enzymes
Lamina Propria
Muscularis
Serosa
Mucosa
Which of the following is true about the GIT?
Waste excretion comes in the process of micturition
Blood supply to entire GIT is called the sphlanchnic circulation
Neural control includes control from the cerebellum
Ingestion means intake of food and water through the nasal cavity
To increase motility, which would be activated?
Sympathetic nervous system
Plexus of auerbach
Plexus of meissner
Secretory cells on the mucosal layer
You are currently in a stressed state thinking about your first only return demonstrations. During this event, the following is true:
Sympathetic innervation will decrease GIT processes
Parasympathetic innervation will increase GIT processes
Myenteric plexus will allow for increased motility
Submucosal plexus will allow for decreased gastric secretions
Allows the tooth to maintain its shape
Dentin
Cementum
Enamel
Crown
These teeth are able to "cut" into food
Cuspids
Incisors
Bicuspids
Molars
Which is true about deglutition?
As bolus enters the esophagus, the upper esophageal sphincter contracts to let it in
The pharyngeal phase makes tongue move up and back against palate to push bolus
The deglutition center is found in the basal ganglia
The process of deglutition is purely mechanical; No enzymes and digestion happen here
Which is true about the oral cavity?
Has a bony partition to nasal cavity called the soft palate
Has a muscular partition to nasal cavity called the hard palate
The uvula is part of the anterior wall of the oral cavity
The cheeks make up the lateral walls of the oral cavity
Oh no! You ate something too hot and you burned your tongue! Which cranial nerve is responsible for this sensation?
CN 5: Trigeminal
CN 7: Facial
CN 9: Glossopharyngeal
CN 12: Hypoglossal
Which are true about wisdom teeth?
They are considered to be your 2nd molars
Everyone gets them at 17 years old into adulthood
Not everyone gets them, in some people, wisdom teeth never erupt
If they do erupt, they would function to tear and shred food
Which of the following are able to conduct air as well as transmit bolus into GIT? (Check ALL that apply)
Oropharynx
Esophagus
Nasopharynx
Laryngopharynx
Which muscle were you using to blow air into your screen?
Boxinator
Buccinator
Orbicularis Oris
Orbicularis Oculi
Which statement is TRUE about the NEURAL controls of the GIT?
The enteric nervous system has the Meissner's plexus which can independently act on GIT muscles
The enteric nervous system has the Myenteric plexus which can independently act on GIT secretory cells
The Enteric system is totally dependent on the Autonomic Nervous System
The Enteric system is regulated by the Autonomic Nervous System
Which is the correct about mechanical digestion?
This is the process of elimination of body wastes through feces or stool
Goal of mechanical digestion is to break down food into smaller particles with enzymes
This is the process of simple particles of food passing through intestinal walls into the blood
Goal of mechanical digestion is to break down food into smaller particles with use of muscular contractions
Which processes happen in the mouth?
Mechanical digestion by process of deglultition
Chemical digestion by production of saliva
Transforming food into chyme
Transforming chyme into bolus
If you were dehydrated...your body would stimulate (choose ALL that apply)
Parasympathetic system for more saliva production so saliva can act as temporary source of water
Sympathetic system for lesser saliva production causing a dry mouth which will stimulate thirst so you'd drink water
Sympathetic system for lesser saliva production causing your body to conserve the water that would have gone out of your saliva
Parasympathetic system for more saliva production causing a moist mouth which will stimulate thirst so you'd drink water
