structural classification of neurons

Question 1

what does anaxonic mean? are neurons small? are there any special anatomical features? can you distinguish dendrites from axons? where can neurons be found? what are the functions of neurons?

Answer 1

anaxonic means "without axon"
small neurons
no special anatomical features
cannot distinguish dendrites from axons
can be found in brain and sense organs (retina)
functions ~ poorly understood

Question 2

unipolar

Answer 2

very long ~ toe to spinal cord

sensory signals to spinal cord ~ very fast

Question 3

bipolar

Answer 3

1 dendritic process and 1 axon

rare ~ found in sense organs - retina, nose, ear

Question 4

multipolar

Answer 4

most common neurons ~ CNS and PNS

2 or more dendrite

motor neurons ~ in CNS and PNS
motor neurons ~ to skeletal muscle
