1F. The Concept of Synapse

Question 1

he physiologically demonstrated that neurons communicate at a junction between them, the synapse

Answer 1

Charles Scott Sherrington

Question 2

they are regarded as the great pioneers of modern neuroscience, and their nearly simultaneous discoveries supported each other

Answer 2

Cajal and Sherrington

Question 3

automatic muscular responses to stimuli

Answer 3

reflexes

Question 4

the circuit from sensory neuron to muscle response

Answer 4

reflex arc

Question 5

TRUE OR FALSE: if neurons are separate from one another, as Cajal had demonstrated, a reflex must require communication between neurons, and therefore measurements of reflexes might reveal the properties of their communication

Answer 5

true

Question 6

many tiny neurons that have no axon and communicate only with their immediate neighbors

Answer 6

local neurons

Question 7

why are local neurons are difficult to study?

Answer 7

because it is almost impossible to insert an electrode into a tiny cell without damaging it

Question 8

greater amounts of stimulation produce greater polarization that spreads over the surface of the tiny neuron called ___

Answer 8

grade potential
