: List the differences between cranial and spinal nerves
The basic difference between the cranial nerves and the spinal nerves is the role they play, in helping our bodies to function properly. [ The body has what is called a peripheral nervous system consisting of more than 100 billion nerve cells, which run all throughout our body, making connections with our brain, as well as other parts of the body, and sometimes with each other. The peripheral
nervous system is composed of two systems the somatic and autonomic nervous system. These nerves connect with both the brain and the spinal cord. Our muscles are controlled by voluntary and sensory receptors in the skin, this is an example of the somatic system. The autonomic system connects the brain stem and the spinal cord to the internal organs, and also regulates the body processes, like heart rate and blood pressure, stomach acid, and the speed of food travelling through our digestive systems. The autonomic nervous system is divided into sympathetic and parasympathetic divisions. Each has a job to do within the body. The sympathetic division helps us to deal with stressful or emergency situations. They help us to know, when to fight and when to take flight. The parasympathetic division helps the body to function, in normal situations. Both divisions regulate our pulse, breathing and blood pressure to keep them stable. The cranial nerves connect our brain to our eyes, ears, nose, throat and other parts of our head, neck and trunk. There are twelve (12) pairs of cranial nerves. The nerves, which connect the spinal cord to with other parts of the body are called spinal nerves. The brain communicates or connects with other parts of the body through the spinal nerves. We have thirty-one (31) pairs of spinal nerves. Spinal nerves and cranial nerves are connected with the somatic and the autonomic parts of the peripheral nervous system. Some nerves are sensory nerves and other nerves are motor nerves, depending upon their function within the body. Read more: ]

During the biggest game of his high school football career, Bill the best wide receiver in the league, leaps high into the air in the end zone to score the game-winning touchdown. A player for the other teams hits him hard, knocking him into the goalpost. Bill crumples to the ground, unmoving. When the EMTs get to him, Bill is paralyzed on both sides of his body and in respiratory arrest. Given your knowledge of the nervous system can you pinpoint the location of Bill's injury?

Weegy: Please contact Weegy Research for this question, it requires in depth research. User: During the biggest game of his high school football career, Bill the best wide receiver in the league, leaps high into the air in the end zone to score the game-winning touchdown. A player for the other teams hits him hard, knocking him into the goalpost. Bill crumples to the ground, unmoving. When the EMTs get to him, Bill is paralyzed on both sides of his body and in respiratory arrest. Given your knowledge of the nervous system can you pinpoint the location of Bill's injury? Explain you arrived at your conclusion Weegy: As for the injury I`d suspect a spinal injury because he was paralyze on both sides of his body. [ The spinal injury is either in the lower neck or upper thoracic (chest) regions because he was in respiratory arrest, but the medics would have to exclude any pre-existing (un-diagnosed ) medical condition . ] (More)

A histogram is drawn by breaking up the data in groups along the bottom of the graph called "classes". Why would you NOT want to have the classes overlap? In other words, what would happen if instead of saying 82 - 84 then 85 - 87 you had 82 - 85 then 85 to 87?
Weegy: 4 units down is the answer. If the 4 was in the absolute value brackets, it would be left 4. (More)

If the classes overllaped, some of the data (from the overlaps) would be shown on the graph twice and so the graph would not give a clear picture. For example, if you had 82 - 85 then 85 to 87, all the data for 85 would appear in both entries on the graph.
