All The Best!!
,Version Exam Module 3.1
Question 1. (3 Pts)
Identify Each Neuron Type Based On Its Role:
1. Connects Information In The Spinal Cord
2. Bicep Contraction
3. Conveys Impulse Regarding Sharp Pinch
1. Interneuron
2. Motor Neuron
3. Sensory Neuron
Interneurons Connect Neurons Within The CNS. Motor Neurons Stimulate Muscle
Contraction. Sensory Neurons Transmit Signals From Receptors To The CNS.
Question 2. (5 Pts)
,1. Dendrites
2. Cell Body (Soma)
3. Axon Hillock
4. Axon
5. Synaptic Terminals
Dendrites Receive Signals, The Soma Processes Them, The Axon Hillock Initiates
Action Potentials, The Axon Conducts Impulses, And Synaptic Terminals Release
Neurotransmitters.
Question 3. (Fill In The Blank With Choices) (3 Pts)
The Region Of The Neuron Where The Action Potential Is Initiated Is The __________.
A. Dendrite
B. Synaptic Terminal
C. Axon Hillock
D. Myelin Sheath
The Axon Hillock Sums Graded Potentials. If Threshold Is Reached, An Action Potential
Begins Here.
Question 4 (3 Pts)
, True Or False:
The Resting Membrane Potential Of A Neuron Is −70 Mv.
A. True
B. False
C. −90 Mv
Most Neurons Maintain A Resting Membrane Potential Of Approximately −70 Mv Due
To Ion Distribution And The Sodium-Potassium Pump.
Question 5 (2 Pts)
Multiple Choice:
Electrical Potential Within A Neuron Is Maintained By The Opening And Closing Of:
A. GPCR
B. Ion Channels
C. RTK
D. Gap Junctions
Ion Channels Regulate Sodium, Potassium, And Other Ions Across The Membrane,
Maintaining Membrane Potential.
Question 6 (3 Pts)
Short Answer
Describe The Process Of Cellular Depolarization.
