SHS 485 EXAM 1 QUESTIONS WITH CORRECT
ANSWERS 2026
1. Myelin sheath provides insulation to the axon to help send signals efficiently
throughout the brain.-ANSWER- What is myelin and what is its purpose?
2. Axon sends signals throughout the brain-ANSWER- What is the computational function of an
Axon?
3. Dendrites receive signals and carry them to the cell body.-ANSWER- What is the
computational
function of a dendrite?
4. The cell body stores information.-ANSWER- What is the computational function of the cell
body?
5. Consists mainly of nerves, cell bodies, and and branching dendrites-ANSWER- Gray Matter
6. Consists mainly of myelin sheath and fatty tissue-ANSWER- White Matter
7. Grooves of the brain-ANSWER- Sulci
8. Folds or ridges of the brain-ANSWER- Gyrie
9. - The primary cortex is only involved in processing information from a single
modality.- The non-primary cortex may be involved in processing information from more
than one modality.-ANSWER- Primary Cortex Vs. Non-Primary Cortex
10. The thalamus is a major relay center connected to many areas of the brain,
including primary and auditory cortex and the primary visual cortex.-ANSWER- Why is the
thalamus such a critical brain structure for many functions including language?
11. - Two hemispheres- Motor control, particularly in making postural adjustments and in fine
tuning
movements- Higher cognitive functions, including language-ANSWER- Cerebellum
12. Scan that looks at the brain-ANSWER- fMRI
13. Scan that looks at the brain activity-ANSWER- EEG
