b. 100 billion d. 1 trillion

1. which part of the brain is the largest?

a. cerebrum
b. brain stem
c. cerebellum
d. medulla oblongata

1. which part of the brain controls memory and reasoning?

a. cerebellum
b. cerebrum
c. brain stem
d. pons

1. coordination of voluntary muscle movement is controlled by the:

a. cerebrum
b. cerebellum
c. medulla
d. hypothalamus

1. which structure interconnects parts of the nervous system and controls life functions?

a. cerebellum
b. cerebrum
c. brain stem
d. cortex

1. the two hemispheres of the cerebrum are connected by the:

a. thalamus
b. pons
c. corpus callosum
d. cortex

1. higher brain functions such as personality and intelligence are controlled by the:

a. cerebellum
b. brain stem
c. cerebrum
d. medulla

1. motor areas of the cerebrum are located mainly at the:

a. bottom
b. top
c. back
d. sides

1. brocas area controls:

a. hearing
b. vision
c. speech muscles
d. balance

1. sensory areas of the cerebrum are located:

a. in one single spot
b. only in the frontal lobe
c. in various places
d. only in the parietal lobe

1. association areas are responsible for:

a. muscle contraction
b. reflex actions
c. interpreting sensory signals
d. breathing rate

1. the thalamus functions to:

a. control emotions
b. receive sensory signals
c. regulate heart rate
d. coordinate movement

1. homeostasis is mainly controlled by the:

a. thalamus
b. hypothalamus
c. pons
d. cerebellum

1. which system is involved with emotions?

a. somatic system
b. limbic system
c. autonomic system
d. cerebellum

Explanation:

coordinates voluntary muscle movement and balance.

1. The brain stem regulates involuntary life functions like breathing and heart rate.
2. The corpus callosum is the thick nerve tract connecting the two cerebral hemispheres.
3. Higher cognitive functions (personality, intelligence) are centered in the cerebrum.
4. The cerebrum's motor areas are primarily located in the top/outer regions (precentral gyrus).
5. Broca's area, in the frontal lobe, controls the muscles involved in speech production.
6. Sensory areas of the cerebrum are distributed (e.g., visual in occipital, auditory in temporal).
7. Association areas process and interpret incoming sensory information.
8. The thalamus acts as a relay station, receiving and routing sensory signals to the cerebrum.
9. The hypothalamus maintains homeostasis (temperature, hunger, hormone regulation).
10. The limbic system (including amygdala, hippocampus) governs emotions and emotional memory.
