27
Q

Advantages and disadvantages of diffusion

A

Advantages: gaining substances like O2 (without it, we would lack oxygen)
Disadvantage: structures must be close to each other in order for a substance to be diffused (70 um of a blood vessel)

28
Q

What neuron relays information into the CNS and is multipolar

A

Interneurons

29
Q

A sensory neuron is

A

Unipolar

30
Q

Signal originates at the end of the peripheral axon and is transmitted past the soma and into the central axon

A

Primary sensory neuron

31
Q
