Nervous system inquiry and research
1) The action potential of a neuron is the reversal of electrical charge inside the neuron. This is triggered by a chemical and then opens up a sodium ion channel. The channel allows positive sodium ions to flow back into the cell, which generates a positive charge.
2) In a neuron, messages are received in the dendrites, which are attached to the head of a neuron. They are long pointy branches that connect to other neurons so that they can receive signals to transmit. The dendrites pass the information into the cell body, then into the axon. Finally, the signal goes into the Saxon terminals and across a synapse to another neuron. The axon is a long and relatively thick tube that goes from the cell body to the axon terminals, which re like are like smaller dendrites.
3) A synapse is the space between a dendrite and an axon terminal where chemicals carry across signals. The ends of two neurons do not directly touch each other. Once an action potential gets to the synapse, then the axon terminal releases neurotransmitters that bind to the next dendrite and pass on an action potential that starts in that dendrite.
4) The difference between a neuron to neuron connection and a neuron to muscular tissue connection is that the muscular tissue connection does not have a synapse. Instead, the neuron is sensory, meaning that it can pick up signals from the surrounding tissue directly. The neuron to neuron connection is a connection of inter neurons, those that carry impulses the long distances needed to trace across the whole body.
5) There are four different parts of the brain that each have different purposes. The first is the frontal lobe, where thinking reasoning, and consciousness are. The back part of the brain at top is the parietal lobe, which is responsible for receiving and acting upon touch sensors. The bottom and frontal part of the brain is the temporal lobe, which is I charge of hearing. The bottom back part is the occipital lobe which is in charge of sight.
