1. the neuron pictured below, is best described as
Answer multipolar
2. true or false, explain why the state is false
Bipolar neurons have a central cell body with two extensions
Answer true
3. List the phases of an action potential in order
Answer 1. resting potential
2. depolarization
3. repolarizarion
4. resting condition
4. true or false , if false explain why the statement is false
the central nervous system consists of the brain and spinal cord

, Answer true
5. name and describe what is occurring in the neurocell membrane in section 2
of the diagram. include the charge of the membrane during this phase
Answer deprivation, sodium gates are opened and the sodium floods into the axon admits the depolarization of
the action potential, causing the charge voltage to go from 0 to +40 mV
6. This part of a reflex is inside the CNS, made up of one or more synapses.
Answer in- tegration center
7. match the following lobes of the brain with the correct function
Answer temporal - contains sensory areas for hearing and smelling
frontal- contain higher levels ex..
pariteal - receives sensory info from body receptors
occipital - interprets visual input
