What happens if one of your leg motor neuron stop functioning?
The leg wouldn't be able to receive or transmit impulses and information from the central nerves system CNS to the muscle and glands
What are the two ways main ways in which neurons are able to react stimuli?
Nerves receive signals meaning that they can respond to a stimulus. Once a stimulus is received by a nerve cell it converts it to a neural impulse which passes along the nerve. Nerves are able to transmit impulses along the length of the nerve cell in the form of an electrical signal.
What are facts about nerves?
Well. Nerves are quite amazing! I happened to be right in the middle of a project about nerves, so I'll share some of my research with ya ^_^ Remember your first time riding a bike without training wheels? It was probably really hard. This is because your nerves hadn't learned the pathway of motion (or the correct path to send messages through). When You finally DID ride your bike, you improved because your nerves had created a "muscle memory". A nerve is a fiber that sends messages through your body telling certain things what to do. Lets say you're about to be hit. What do you do? You probably put out your arm in front of you in some sort of defense. Your nerves are telling you to do that, because they sense that something is about to happen. Nerves are made up of TONS of Neurons. The fibrous part of your nerves (neurons) is covered by a fatty material called myelin. This is why messages are able to travel so quickly through your nerves. At the end of the nerve, a synaptic terminal full of extremely tiny sacs which hold neurotransmitter chemicals transfers impulses from nerve to nerve, or from a nerve to a muscle cell. Electrical nerve impulses travel through the neurons, which then drop off the impulses in these sacs and release the chemicals. These chemicals find their way to a different neuron, which sparks an electrical charge that moves the nerve impulse forward. You'd think this takes about 2-3 minutes, but actually a neuron fires 500 times per second when they're "excited". Firing basically means to send out the neurotransmitter chemicals. Hope this helped with whatever you were doing ^_^
Which parts of the frog's nervous system can be observed in its abdominal cavity and hind legs?
In the abdominal cavity you should be able to observe vague nerves which carry nerve impulses to the liver, heart, lungs, pancreas, intestine, and stomach. Sympathetic ganglia may also be observed. In the hind legs you should be able to observe the sciatic nerve.
Why do you have nerves?
You have nerves so that you are able to move. If you didn't have any nerves you would be a very still person.

Why might a person with a brain injury be able to understand the speech of others but not be able to speak?
In the brain, the nerves for speaking are in a different location from the nerves for listening. If the "Speaking" nerves are damaged, the person may not be able to speak, but since the "Hearing" nerves are intact, can still understand others' speech.
Are cns nerves able to regenerate?
False
What is the adaptive advantage of faster conduction of nerve impulses?
You are able to respond to things more quickly. If you are being attacked or need to move quickly, these nerve impulses can help.
What is the only kind of cell able to transmit nerve impulses?
nerve cell
What nerves allows you to ride a horse?
You need all the nerves in your body to be able to ride a horse and ride it well.
What role do nerves play in your body?
Nerves give you feeling all over your body. Pain, numbness, being able to feel; it's all from nerves. Nerves carry signals to and between part of your body. When you touch something hot, a sensation goes through the hand to the nerves, and the nerves give signals to the brain. The brain recognizes it is hot, so the brain sends signals to the nerves in your hand to withdraw.
