Neurons: Conduction and Transmission

Question 1

What is conduction?

Answer 1

the ELECTRICAL signal that is generated by a neuron that travels WITHIN the neuron from one location to another

Question 2

What is transmission?

Answer 2

the CHEMICAL signal that is generated by one neuron and received by another neuron or effector tissue (ie: muscle)

Question 3

Look at the slide of all the different parts of a neuron

Question 4

Myelination in the PNS is known as this type of cell and myelination in the CNS is known as that

Answer 4

Schwann Cell and Oligodendroglia

*look at picture on slide

Question 5

What do selective barriers do?

Answer 5

excludes certain substances that float in the surrounding fluid from entering the cell

Question 6

establishment of potential difference allows…..

Answer 6

the environment on either side to be different

Question 7

• Enzymatic proteins attract reacting molecules to the membrane surface
• Those needed for metabolic pathways are aligned adjacent to each other to act like an assembly line for the reactions.
