The rate of firing of the postsynaptic neuron depends on the amount of ______ input it receives from the presynaptic neuron.

1 answer:

6 0

The postsynaptic potential is the membrane potential, which takes place in the neuron present post synapsis (after the chemical synapse). The presynaptic neuron releases neurotransmitter, which causes the firing in the postsynaptic neurons.

The firing of the post synaptic neuron depends on the excitation and inhibition inputs received from the presynaptic neuron. The firing is the resultant of the summation of excitatory and inhibitory potential. In case, the excitatory potential is greater than inhibitory potential, the post synaptic neuron would be excited. in case, inhibitory potential is greater than excitatory potential, then the post synaptic neuron would be inhibited.

Hence, the correct answer is option d.

Which of the following is maintained across the terminals of a battery?

astraxan [27]

Answer:

Option D, both A and B

Explanation:

The potential difference is created across a battery (between its two terminal –one positive and the other one negative) when work is done to move a charge from one point to another. This potential difference is measured in volts. 1 volt is the potential difference between two points when one joule of potential energy is spent to move a charge of one coulomb from one point to the other.

Voltage drop across a circuit is the amount of electric current lost due to resistance/ impedance with in the cables of the circuit.

Hence, both potential difference and voltage drop occurs across the circuit,

Option D is correct.
