OPTA 215(Anatomy and Physiology of speech, language, and voice production)
What is wernick's Area?
An area located in the Temperal lobe where it comprehends speech and language; and formation of language
Wernicke's Aphasia
This happens when damage to the wernicke's area. It causes fluent sounding speech but incomprehensible content(word salad)
Broca's Area
Located in the frontal lobe. Responsile for speech motor planning
corpus callosum
Band of communication fibers allows to hemisperes to communicate
motor humunculus
areas of body that requir greater muscle coordination
Pariental lobe
Sensory information
Frontal lobe
primary motor control
temporal lobe
auditory info
occiptal lobe
visual lobe
Respitory system functions
o2 exchange, power souce for speech production
Boyle's Law
-energy= Pressure x volume ex. when we flatten the diaphram we in crease volume then pressure decrases in thoracic cavity resulying air to flow in
- rest = tidal volume
- activity = inspiratory or expiratory reserves volume
- total lung capacity= tidal+insopiratory+expiratory
Cranial Nerve V: Tregaminal
muscle for chewing, eardrum tension, soensory face and head
Cranial Nerve VII: Facial
expressions, sensory of tongue and pharnyx
Cranial Nerve VII: Accoustic
hearing and balence
Cranial Nerve IX: Glossopharnygeal
motor pharnyx, swallowing, sensory for tongue and pharnyx
Cranial Nerve X: Vagus
Motor of swallowing, laryngeal control, respatory cardiac, gasto systems
Cranial Nerve XI: Accesory
shoulder arm and throut movements
Cranial Nerve XII: Hypoglossal
Tongue movements
Breathing to substain life
- no impeding of air
- 10-15 % of vital capacity
- equal amount of time inhale/exhale
Breething for speech
-impeding air
-40% of vital capacity
-shortened inhalation to about 10%
Larngeal System
AKA vocal box
2 speech related processes; valve to open flow of air, open and closing of vocal folds
Alveoli
where o2 exchange happens look like little sacs of capillaries
Bronchioles
Branches of the main bronchus
Main bronchus
The Two branches that go into out lungs
Diaphram
the muscle under out lungs
