CBL study 3
- Speech consists of the voice, articulation and language. Describe their
anatomical basis.
Language (Broca's area)
- Left hemisphere: speech production + articulation: ability to articulate ideas + use words correctly
Wernicke's Area
- Posterior superior temporal lobe: Comprehension + long processing
Articulation
- Vocal tract articulates (tongue, soft palate and lips): modify voice sound + produce recognizable words
Angular Gyrus
- Associate multiple language - related info: associate perceived word with different images, sensations and ideas
Voice
Larynx
Sound production, air passage in breathing
-
Vocal fold (cords)
Vibratory component of voice box, cover, vocal ligament and body
- What clues point to the aspects of speech that are affected here?
Articulation + voice: understanding + using language normal. Choking could mean change in innervation to glottis
- Where in the nervous system could a single lesion cause numbness in
one leg and weakness in the other?
-
- What is the most common disease causing patchy lesions in the central
nervous system?
