48.1 Neuron Organization/Structure = Function In Information Transfer

Question 1

3 stages in information processing:

Answer 1

1) sensory input
2) integration
3) motor output

Question 2

sensory neurons

Answer 2

transmit information from sensors that detect external stimuli (eyes) or internal stimuli (blood pressure) to processing centers in the brain/ ganglia

Question 3

interneurons

Answer 3

• most of the neurons in the brain are interneurons

- make only local connections

Question 4

nerves

Answer 4

extend out of processing centers in bundles

-triggers muscle/gland activity

Question 5

motor neurons

Answer 5

transmit signals to muscle cells causing them to contract

Question 6

central nervous system

Answer 6

brain + nerve cord

-neurons that carry out integration found here

Question 7

peripheral nervous system

Answer 7

the neurons that carry information into and out of the CNS
