Systems
overriding system that controls all aspects of speech
nervous system
the four main types of tissue
epithelial, muscle, connective, nervous
structure to which the muscle is attached that is not moving
the origin
examples of using upper and lower extremities to communicate
AAC device users, sign language
embryology includes these months of development
the first two months
system in charge of speech perception
auditory system
blisters are damage to this type of tissue
endothelial because they are filled with fluid
3 types of muscle tissue
striated, cardiac, smooth
the primary source of energy for speech comes from this subsystem
respiration
after the second month, the embryo is called this
fetus
four subsystems of speech production
respiration, phonation, articulation, resonance
three types of dense connective tissue
tendons, ligaments, fascia
other names for the cartilaginous joint
amphiarthrodial and yielding
this subsystem transforms vibration into sound production
phonation
this week is when major neural development takes place
week 4
two structures involved in phonation
larynx and vocal folds
vertebral discs are an example of this type of cartilage
fibrous b/c they absorb shock and cushions
explain an antagonistic muscle
opposes major action
the digestive system overlaps with these subsystems of speech
respiratory, articulation, resonance
this develops into the structures of the central nervous system
neural tube
explain what happens in resonance
three types of bones and example for each
Flat; frontal, occipital, parietal
Long; arms and legs
Short and irregular; ossicles in inner ear, hands and feet, vertebra
endomysium
In speech perception, after sensory info is sent to the cortex, it goes here
Heschl's gyrus (primary auditory cortex)
this develops into the dorsal spinal cord
alar plate
