Types of Neurons

Question 1

presynaptic neuron

Answer 1

neuron located before synapse

Question 2

postsynaptic neuron

Answer 2

neuron located after synapse

Question 3

multipolar neuron

Answer 3

• 3+ extensions from cell body

- 1 axon, many dendrites

Question 4

bipolar neuron

Answer 4

• 2 extensions from cell body

- serve as special receptor cells in visual & olfactory systems

Question 5

unipolar neuron

Answer 5

• 1 extension off cell body that branches into 2
• one branch = central process (runs to CNS)
• other branch = peripheral process (runs to sensory receptor)

Question 6

sensory neurons

Answer 6

• unipolar

- carry info from skin/internal organs to CNS

Question 7

interneurons

Answer 7

• only found in CNS
• typically multipolar
• transmit info between parts of CNS

Question 8

motor neurons

Answer 8

• multipolar

- send messages from CNS to PNS
