Exam Questions and CORRECT Answers
Myelinated - CORRECT ANSWER - myelin is an insulating layer, which conducts signals
through the axon at a much faster speed
EPSPs - CORRECT ANSWER - are graded potentials that can initiate an AP in the axon,
produce a graded potential that lessens the chance of an AP in an axon. - small depolarization is
created
IPSPs - CORRECT ANSWER - produce a graded potential that lessens the chance of an
AP in an axon. - small hyperpolarization is created.
Clusters of RER and free ribosomes in neurons are called - CORRECT ANSWER - nissl
bodies

ANSWER - the axon hilcock
Spatial Summation- - CORRECT ANSWER - 2 synapses required to induce EPSPs
EPSP - CORRECT ANSWER - excitatory postsynaptic potential
IPSP - CORRECT ANSWER - inhibitory postsynaptic potential
If the sodium potassium pump in the plasma membrane fails, something that would NOT happen
would be - CORRECT ANSWER - rise in intracellular Potassium K ions

neuron
Afferent- - CORRECT ANSWER - sensory neurons that carry nerve impulses from
sensory stimuli towards the central nervous system and brain
Sensory - CORRECT ANSWER - Afferent
efferent neurons - CORRECT ANSWER - are motor neurons that carry neural impulses
away from the central nervous system and towards muscles to cause movement
