Unit 3 Bio Review

The Somatic Nervous System:

• Subdivision of the peripheral nervous system that controls voluntary muscle movements.

• Subdivision of the central nervous system that controls voluntary muscle movements.

• Part of the autonomic nervous system that controls voluntary muscle movements.

• Part of the Sympathetic nervous system that controls voluntary muscle movements.

Miranda is walking in a dark alley and she see's a dark shadowy figure, her palms begin to sweat and her heart begins to race. This portrays which part of her autonomic nervous system?

• Somatic

• Sympathetic

• Central

After Mirandas threatening walk home she sat in her room and felt her heart rate slow. Which part of the autonomic nervous system was being used?

• Central

• Somatic

• Sympathetic

• Parasympathetic

This part of the brain (aka the sensory switchboard) would be activated while all types of sensory neurons are being sent to your brain except your sense of smell:

• Cerebellum

• Wernicke's Area

• Thalamus

• Parietal Lobe

This structure controls your fear and aggression responses:

• Parietal lobe

• Amygdala

• Medulla

• Reticular Formation

Which brain scanning technique measures brain waves, and electrical activity in the brain?

• Computed Tomography (CT Scan)

• Position Emission Tomography (PET Scan)

• Electroencephalogram (EEG)

• Magnetic Resonance Imaging (MRI)

Which is the correct order in which a neuron fires?

• Action potential, threshold, refractory period, resting potential

• Resting potential, action potential, threshold, refractory period

• Threshold, action potential, refractory period, resting potential

• Resting potential, threshold, action potential, refractory period

While speaking, Miranda could not physically come up with the correct way to say what she needed to say or talk in a fluent manner, this could be caused by:

• Thalamus Aphasia

• Wernickes area aphasia

• Brocas Area aphasia

• Cerebellum Aphasia

Who discovered the idea that there are separate functions for each lateral half of the brain?

• Sigmund Freud & Carl Rodgers

• Roger Sperry & Michael Gazzaniga

• Paul Broca & Carl Wernicke

• Abraham Maslow & Erick Erickson
