Review Unit 2 day 1

The result of the evolutionary process that preserves traits that enhance the adaptation of an organism and suppresses traits that do not is called

• habituation

• accommodation

• natural Selection

• eugenics

• species assimilation

The role of the parasympathetic division of the autonomic nervous system is to

• facilitate the body’s fight-or-flight response

• prepare the body to cope with stress

• promote rapid cognitive processing

• prompt the body to use its resources in responding to environmental stimuli

• establish homeostasis after a fight-or-flight response

Which is the correct order/sequence of the parts of a neuron in a neural impulse?

• axon, dendrite, cell body, synapse
• dendrite, axon, cell body, synapse
• synapse, axon, dendrite, cell body
• dendrite, cell body, axon, synapse

Neurons that travel toward the central nervous system are called

• afferent/sensory neurons

• efferent/motor neurons

• exit neurons
• CNS neurons

Myelin would be which color of structure?

• the red one

• the blue one

• the green one

• the purple one

This is made up of the brain and spinal cord

• Central Nervous System (CNS)

• Peripheral Nervous System (PNS)

• Autonomic nervous system

• Somatic nervous system

This is the electrical charge that travels down an axon when a neuron is firing

• Resting Potential
• Action Potential/Electrical Impulse

• Threshold
• Refractory Period

I support neurons and help produce myelin what am I?

• Axons

• Dendrites

• Glial cells

• Cell bodies

In order for a neuron to have an action potential, the neuron must receive more

• excitatory neurotransmitters
• inhibitory neurotransmitters
• agnostic neurotransmitters
• antagonistic neurotransmitters

A neurons reaction of either firing (with a full length response) or not firing.

• all-or-none response

• refractory period

• threshold

• action potential
