1
New cards

unmyelinated axon

-'naked' axon
-small;short, lengthy fiber

2
New cards

unmyelinated axon

larger dendritic field

3
New cards

unmyelinated axon

pupose: to receive as much input as possible
->i.e. "highly sensitive"

4
New cards

unmyelinated axon

location: common in cns; far less common in pns

5
New cards

unmyelinated axon

advantages: more neurons in less space and a greater ability to detect stimuli

6
New cards

unmyelinated axon

disadvantages: slow and energy inefficient

7
New cards

myelinated axon

-highly "insulated" axon
-large; longer lengths, thick

8
New cards

myelinated axon

small dendritic field

9
New cards

myelinated axon

receive input and transmit impulse quicly

10
New cards

myelinated axon

common in both cns(tracts) and pns(nerves)

11
New cards

myelinated axon

exceptionally fast and energy efficient

12
New cards

myelinated axon

disadvantage: large
