b. right hemisphere
c. cerebellum
d. thalamus

1. the cerebrum primarily controls which of the following?

a. reflexes only
b. voluntary actions and personality
c. breathing
d. heart rate

Explanation:

the cortex.

1. The area beneath the cerebral cortex is primarily white matter, composed of myelinated axons.
2. A dominant hemisphere is the one an individual relies on for most cognitive and motor functions.
3. Around 90% of the population has a dominant left hemisphere, associated with language.
4. The left hemisphere is primarily responsible for language and logical/analytical skills.
5. The right hemisphere is linked to musical and visual spatial interpretation.
6. Spatial orientation is a core function of the right hemisphere.
7. The cerebrum governs voluntary motor actions and higher cognitive functions like personality.
