3 - neural signaling, chemical synapse

Question 1

ligand gated ion channels

Answer 1

IONTROPIC RECEPTORS
to which neurotransmitters can bind to

Question 2

4 types of ion channels

Answer 2

gated, non-gated, ligand-gated and strech gated

Question 3

gated ion channel are triggered by the following mechanism

Answer 3

VOLTAGE
when voltage changes they open

Question 4

ligand gated ion channels open when …

Answer 4

chemical (neurotransmitter) binds to them.

Question 5

strech gated ion channels are sensitive to

Answer 5

stress

Question 6

4 types of chemical synapses

Answer 6

axo-dendritic, axo-somatic, axo-axonic, dendre-dendritic

Question 7

axo-dendritic chemical synapes, the axon synapes to ..

Answer 7

the next neurons dendrites

SO THE BASIC ONES

Question 8

axo-somatic chemical synapses, the axon of neuron A synapes to…

Answer 8

the cell body (soma) of neuron B

Question 9

axo-axonic chemical synapses, 2 axons synapse …

Answer 9

ON EACHOTHER (2 different neurons)

• can make next neuron releasemore or less neurotransmitter
  A influences input of B to C

Question 10

dendro-dendritic chemical synapses

Answer 10

dendrites of 2 neurons are connected to each other, they can communicate
