Question

To activate a neuron, first a stimulus must reach the ____. At the location ____ channels open and this positively charged ion enters the cell.

Sodium, potassium, ATP, synapse, depolarize, axon, repolarize, action potential, dendrite, terminal bulb, neurotransmitter

Answer 1

The sodium-potassium pump is an enzyme complex that exchanges sodium and potassium ions across the membrane of the neuron. The sodium-potassium pump uses ATP to send 3 sodium ions out of the cell in exchange for taking in 2 potassium ions.

The functions of the nervous system—sensation, integration, and response—depend on the functions of the neurons underlying these pathways. To understand how neurons are able to communicate, it is necessary to describe the role of an excitable membrane in generating these signals. The basis of this process is the action potential.

Step-by-step explanation:

yw

Answer 2

1.Synapse

2. Sodium potassium

Step-by-step explanation:

the synapse is the space between two neurons also where neurotransmitters are transfered and where action potential takes place which NA k pump is needed.
