8th cranial nerve
person's hearing and balance.
This nerve contains two components: the vestibular nerve and the cochlear nerve. The vestibular nerve helps the body sense changes in the position of the head with regard to gravity. The body uses this information to maintain balance.
Blood supply
provide many paths for blood to supply oxygen and nutrients to the brain. Carotid arterial system
Left and right common carotids internal and external carotid arteries (on left and right)
Internal arteries anterior cerebral artery (ACA) and middle cerebral artery (MCA)
Vertebrobasilar arterial system Left and right subclavian arteries vertebral arteries (2) basilar artery (1) left and right posterior cerebral arteries (PCA)
voluntary motor movements
Motor strip (M1) primary motor cortex, Bottom half deals with movement and speech
upper half deals with face movement/voluntary movement.
auditory stimuli
Primary auditory cortex- How the brain interprets auditory signals and speech signals- Specific neurons respond to specific frequencies.
Processing sounds
involved in auditory processing, including language, but also has been implicated as a critical structure in social cognition.
processing of speech and language in Broca's area.
stores information about the sounds in words and sequencing of these sounds
opposite of glutamate. Inhibits action potential.
Primary inhibitory NT: major inhibitory transmitter is its derivative γ-aminobutyric acid (GABA)
This is a primary neurotransmitter that transmits impulses across the synaptic cleft.
produced by peripheral motor neurons to excite muscle; primary neurotransmitter for PNS.
Primary NT at NMJ: Acetylcholine (ACh), produced by peripheral motor neurons to excite muscle
A type of glial cell that forms insulating myelin sheaths around the axons of neurons in the peripheral nervous system.
myelin for PNS neurons (can regenerate)
play essential roles in the development, maintenance, function, and regeneration of peripheral nerves.
speech production
Major language area, located inferior frontal gyrus, controls motor speech
Efferent leads AWAY from CNS ( responsible for moving muscle, motor pathways)
Afferent leads TOWARD CNS (doing, feeling and sensing, sensory pathways)
Precentral gyrus
An important part of the frontal lobe. We know that specific neurons are associated with specific parts of the body. The more developed a motor movement is, the more
Skills, fine-tuned motor movements, delicate, voluntary
loss of ability to understand or express speech, caused by brain damage.
Aphasia is a disorder that results from damage to portions of the brain that are responsible for language.
For most people, these areas are on the left side of the brain.
The disorder impairs the expression and understanding of language as well as reading and writing. Aphasia may co-occur with speech disorders, such as dysarthria or apraxia of speech, which also result from brain damage.
A high-level motor disturbance (disorder of learned movement) that is not caused by paralysis, weakness, or incoordination and cannot be accounted for by sensory loss, comprehension deficits, or inattention to commands
Motor association areas
2 divisions of the nervous system
Central nervous system: ependymal cells, microglia, oligodendrocytes, astrocytes
PNS: Schwann cells
Peripheral nervous system (includes cranial nerves and spinal nerves) and central nervous system (encased in bone, includes brain and spinal cord)
Left hemisphere (contains motor fibers) usually deals with language, speech, and analytic processing.
Sees the details but not the big picture.
The right hemisphere (contains sensory fibers) deals with emotions, musical skills, metaphors, and humor.
Sees the big picture but not the details.
reception, integration, transmission, and transfer of information
Carry out information
Neurons are cells that communicate with other cells.
motor activities of an automatic nature such as walking, talking, balance/posture; coordination
Balance, coordination movement, sensation
Damage = ataxia
Name the cerebral artery supplying the following areas:
"leg area" of the motor strip:
Frontal pole:
Broca's area:
Wernicke's area:
Motor strip (except leg area):
Primary visual cortex and occipital pole:
"leg area" of the motor strip: ACA
Frontal pole: ACA
Broca's area: MCA
Wernicke's area: MCA
Motor strip (except leg area): MCA
Primary visual cortex and occipital pole: PCA
Collateral blood flow in brain
cerebral arterial circle, supplies blood to the brain and surrounding structures
Circle of Willis circle of arteries is the connection between ACA, MCA, and PCA. Function is to protect (prevents stroke from happening). Most common strokes happen in the MCA because there is no extra protection.
When there is multiple cultures within a place or even a person
French-Canadian for an example because in Canada, French and English are both spoken a lot because those are the bigger languages in Canada.
There are also religious differences that are common in a multicultural society, which different holidays are celebrated
Negative transfer/language interference:
Take a structure you have in native language and transfer it to second language, but those structures don't exist
EX: using structure of native language (Serbian) and transferring it to english, the grammatical structures don't match up
Positive transfer: "Bootstrapping"
Using the knowledge of first language and transferring it into the next language, and it "works"
Ex: german has more morphemes than english; transfer rich morphosyntactic knowledge from german to english -May pick up morphology quickly because already have background knowledge on more complex structures
Language disorder is having difficulties in more than one language
Language difference is having more knowledge in one language than another. (Having issues with L2, not L1)
Work with family to get background of child and their language usage -Parent concerns Dynamic (fluid) assessments: looks at what you are capable of learning
Criterion
Language sampling
Working with interpreters: Using direct language: Talk to the client, not the interpreter
EX: don't say "hey interpreter, tell the client ___"
Brief them before the session, so they know what they're interpreting (ex: types of assessments)
Debrief them after the session
"Is there anything else I need to know?"
Don't use family or kids Too involved within caregivers life; makes it bias Interpreter/translator needs own licensure
Setting you're in needs to provide interpreter ~ due to access of language
To be a bilingual slp in schools, need bilingual endorsement on PEL license
Cultural humility: identified as life-long learner Realize how you view the world, but know that there is more to learn about other cultures Culturally competent: identified as not needing to learn any more
Learned everything and don't need to learn any more
Ethnographic interview: allow client to tell you about their culture (their food, their customs, etc.
Vowel quadrilateral (parallelogram) What vowels are high and low Look at visual Questions related to phonemes Place, manner, voice, age of acquisition https://adventuresinspeechpathology.com/freebie-library/ Look at brown's stages Age ranges that match with different stages What morphemes are required Calculation of MLU
How to calculate it
What counts as a morpheme
What repetition do we not count
What words count as more than 1 morpheme -Tense
Contractions Mean length utterance (MLU)
What counts as a morpheme -What words count as more of a morpheme prefix/suffix Identity morphemes in a sentence to calculate MLU Phonological processes Formal definitions of morphology, syntax, phonology vs phonetics
Glides involve a gliding motion of an articulator and are always prevocalic
/w/ as in wagon
/j/ as in yellow
Phonology is the study of language by examining the inventory and structure of the sounds of human speech.
does not study one particular language abstract sound patterns and structures. Phonetics is the study of speech sounds.
Phonetics is what the speech sounds are (production and perception)

Paired with a verb in present progressive
EX: Justin is interviewing for a new job right now. Copula be
Primarily used w adj or nouns
Links subject to another subj or adj.
EX: Justin is smart. // Justin is a man.

Get information out more quickly
May not be as formal/advanced clausal structure
Use high frequency words
Core words make up 80% of our conversations
Age ~ MLU 2.5 - 3 years ~ 3.23 morphemes 3 - 3.5 years ~ 3.81 morphemes 3.5 - 4 years ~ 4.09 morphemes 4 - 4.5 years ~ 4.57 morphemes 4.5 - 5 years ~ 4.75 morphemes 5 - 5.5 years ~ 4.88 morphemes 5.5 - 6 years ~ 4.96 morphemes 6 - 6.5 years ~ 5.07 morphemes
1 False starts, reformulations, or repetitions unless the repetition is for emphasis (e.g. "[then] then [he go] he went to the zoo" is counted as 6 morphemes; "No! No! No!" is counted as 3). 2 Compound words, reduplications, and proper names count as single words (e.g. fireman, choo-choo, Big Bird). 3 Irregular past tense verbs and irregular plurals count as one morpheme (e.g. took, went, mice, men). 4 Diminutives (e.g. doggie, horsie, dolly) and catenatives (e.g. gonna, wanna, hafta) count as one morpheme. 5 Fillers (e.g. um, well, oh, um hmm).
