the means of travel within and between neurons is different because:
a. electrical signals move impulses within the neuron, while chemical signals move the impulses between neuron.
b. chemical signals move the impulses within the neuron, while electrical signal moves impulses between neurons.
c. chemical signals initiate all messages in the dendrite, but changes to electrical in the axon.
d. the axon will not receive electrical signals, but the chemical signal pushes the impulse
i think it's c what about you
hello somebody
Please have patience. Our psychology expert spends a couple hours a day tutoring on Jiskha, but he's not online now. He may not be back online until tomorrow.
Definitely A. Electrical impulses within the neuron cause release of chemicals into the synapse. The electrical impulse goes throughout the neuron rather than just the axon, so its not C.
(a) electrical signals move impulses within the neuron, while chemical signals move the impulses between neuron
The correct answer is b. Chemical signals move the impulses within the neuron, while electrical signals move impulses between neurons.
To understand why this is the correct answer, let's break it down:
Within a neuron, an electrical signal called an action potential travels from the cell body down the axon to the axon terminal. This electrical signal is generated by changes in the distribution of charged particles (ions) across the cell membrane. These changes create a wave-like depolarization effect that travels down the axon.
However, at the synapse (the junction between two neurons), the electrical signal cannot directly cross over to the next neuron. Instead, the electrical signal is converted into a chemical signal. When the electrical signal reaches the axon terminal, it triggers the release of neurotransmitter molecules into the synapse. These neurotransmitters then bind to receptors on the neighboring neuron, transmitting the signal from one neuron to the next.
Therefore, the means of travel within a neuron involves electrical signals (action potentials), while the means of travel between neurons involves chemical signals (neurotransmitters). This is why option b is the correct answer.
