35
What are the protective membranes of the CNS called?
meninges
36
The thin, delicate fibrous sheet that is tightly adhered to the surface of the brain & spinal cord
Pia mater
37
The spider, weblike mesh of fibers which provides a region through which CSF can flow
arachnoid mater
38
the tough durable sac made of dense fibrous tissue that surrounds the brain & spinal cord
Dura mater
39
Describe the ventricles of the brain
1. Right & Left lateral ventricles 2. third ventricle- midline of the brain 3. fourth ventrible- at the base of the cerebellum
40
What three segements form the brainstem?
1. Midbrain 2. Pons 3. Medulla
41
Describe the medulla & its function
- lowermost segment of the brainstem - controls autonomic functions- respiration, cardiac rate, reflex motor responses such as coughing, vomiting, & swallowing
42
Describe the pons & its function
- located between the medulla & the brainstem | - mastication, facial expressions, eye movements (cranial nerves)
43
Describe the midbrain & its function
the most rostral (highest) portion of the brainstem | -coordination of phonatory, articulatory, and respiratory movements
44
What does "cerebellum" mean in Latin
"little brain"
45
Function of the cerebellum
motor control- improve future movements by sending error correction information to the motor cortex of the cerebrum
46
What are the lobes of each cerebral hemisphere?
Frontal, parietal, temporal, occipital
47
Which lobe is anterior to the central sulcus and superior to the lateral fissue?
Frontal lobe
48
Which part of the frontal lobe contributes to executive functioning- attention, monitoring, planning, & decision making?
Prefrontal cortex
49
Which area of the frontal lobe is important for language production?
Broca's area
50
The primary motor cortex (precentral gyrus) is ______________ to the premotor cortex
posterior
51
Which lobe is posterior to the central sulcus & superior to the lateral fissure?
Parietal
52
What is the anterior most portion of the parietal lobe?
Postcentral gyrus (primary sensory cortex)
53
Which lobe is inferior to the lateral fissure & anterior to the occipital lobe?
Temporal lobe
54
What is another name for the primary auditory cortex?
Heschl's gyrus
55
Which area of the temporal lobe is important for language comprehension?
Wernicke's area
56
Brodmann's area 44 & 45
Broca's area
57
Brodmann's area 22
Wernicke's area
58
What are the two types of motor pathways?
1. Direct motor pathway- Pyramidal system | 2. Indirect motor pathway- Extrapyramidal system
59
What is the function of the direct motor pathway?
control of skilled, voluntary movements of our extremities
60
What are the two tracts of the direct motor pathway (pyramidal system)?
1. Corticospinal tract | 2. Corticobulbar tract
61
Describe the corticospinal tract
Upper motor neurons originate from the primary & premotor cortex, the fibers extend through the internal capsule (above the midbrain), pyramidal decussation occurs in the brainstem (cross over) to control muscles on the contralateral side of the body, tracts synapse with lower motor neurons
62
Describe the corticobulbar tract
Function: control muscles of face, head, & neck Upper motor neurons originate in the primary motor cortex, axons project contralaterally or bilaterally onto cranial nerve motor nuclei
63
Typically, corticobular control is...
bilateral
64
What are two exceptions to bilateral innervation of the corticobular tract?
1. contralateral control of lower face (CN VII) | 2. contralateral control of the tongue (CN XII)
65
What is the indirect activation pathway (extrapyramidal system) involved in?
reflexes & coordination of various muscle groups, modulation & regulation of posture, balance, tone, & some voluntary movements
66
Which lung is smaller?
Left lung
67
How many lobes are in the R lung?
3
68
How many lobes are in the L lung?
2
69
Aspiration is more common in which lung?
Right
70
What are the four major muscle groups involved in respiration?
diaphragm, abdominals, internal & external intercostals
71
Quiet breathing versus Speech breathing
Quiet breathing is passive & involuntary. | Speech breathing is active & volitional.
72
Where is the larynx located?
in the neck- at the level of C3-C6
73
What does the larynx connect
Connects the oropharynx & laryngopharynx to the trachea.
74
Why is the larynx important during swallowing?
Airway protection
75
What are the midline, unpaired cartilages of the larynx?

76
What are the paired cartilages of the larynx?
1. Arytenoids 2. Cuniforms 3. Corniculates
77
Describe the location of the VF
Extend from the anterior thyroid cartilage to the vocal processes of the arytenoids
78
What are the 3 layers of the VF?
1. Vocalis muscle 2. Lamina propria 3. Superficial
79
The area between the VF
glottis
80
Describe the cycle of voicing
1. VF are adducted- closing the glottis 2. subglottic air pressure builds up 3. air pressure eventually blows open the vocal folds 4. Air rushes through the glottis & pressure decreases 5. the decrease in pressure & pliable nature of the VF, closes the VF 6. with the VF closed, another cycle begins
