Question

I've already tried the one that says incorrect.

1. An EPSP (i.e., Excitatory PostSynaptic Potential) causes ___.

- an action potential to move down the axon

- K+ channels to open and the outflow of K+ from the cell

- Na+ channels to open and the inflow of Na+ into the cell

(incorrect) - a change in the membrane potential that makes the cell less likely to produce an action potential

2. Which type of voltage-gated channels are only present in the membrane of neurons near the synapse?

  voltage gated Ca++ channels

   voltage gated Na+ channels

   (incorrect) - voltage gated Cl- channels

   voltage gated K+ channels

  

Answer 1

Answer 1) d)

Na+ ions to open and inflow of Na+ into the cells.

The EPSP occurs when the excitatory post synaptic membrane is more prone to fire an action potential.

during the process of an action potential, the positively charged ions move inside the cell while the negatively charged ions outside the cell, and the whole process is mediated between ions which are sodium and potential, and typically the ion which leads to the generation of EPSP is the sodium channels.

Answer 2) a

Voltage gated Calcium channels.

These are typically present at the synapses and is responsible for maintaing the action potential there. Whenever there is a depolarisation of the action potential at the presynaptic membrane, these channels (Calcium) open up and allow the inflow of the Calcium

I hope i was able to help you with the answers !:)
