AP Psychology: Unit 1 - The Brain & Nervous System

The branching extensions of a neuron that receive messages and conduct impulses toward the cell body are called:

• dendrites

• axons

• synapses

• myelin sheaths

Which part of the neuron speeds up neural transmission by insulating the axon?

• dendrites

• myeline sheath

• axon terminals

• soma

Chemical messengers that cross the synaptic gap between neurons are known as:

• hormones

• action potentials

• neurotransmitters

• glial cells

The largest part of the human brain, responsible for higher-order thinking and decision-making is the:

• cerebellum

• cerebrum

• hippocampus

• amygdala

Which brain structure coordinates voluntary movement and balance?

• hypothalamus

• medulla

• thalamus

• cerebellum

Which brain structure plays a central role in processing emotional responses, such as fear and aggression?

• hippocampus

• amygdala

• cerebellum

• hypothalamus

The hippocampus is most directly involved in:

• regulating hunger and thirst

• speech production

• memory formation

• controlling motor movement

The hypothalamus is primarily responsible for:

• balance and coordination

• sensory input processing

• coordinating voluntary movement

• regulating thirst, hunger, and body temperature

The large band of neural fibers that connects the two brain hemispheres is the:

• corpus callosum

• cerebellum

• thalamus

• sensory cortex

The lobe of the brain responsible for reasoning, planning, and voluntary movement is the:

• frontal lobe

• temporal lobe

• parietal lobe

• occipital lobe
