Which statement explains the difference between a nerve that is connected to the skin and a nerve that is connected to a muscle?
The nerve that is connected to skin is a motor neuron; the nerve that is connected to a muscle is a sensory neuron. The nerve that is connected to skin receives stimuli information from the external environment; the nerve that is connected to a muscle receives processed stimuli information from the brain. The nerve that is connected to skin is part of the central nervous system; the nerve that is connected to a muscle is part of the peripheral nervous system. The nerve that is connected to skin helps the body maintain homeostasis; the nerve that is connected to a muscle supports the body so it can stand upright and move from place to place.
"The nerve that is connected to skin receives stimuli information from the external environment; the nerve that is connected to a muscle receives processed stimuli information from the brain."
When you receive, for example, a touch on your arm, the nerves connected to your skin transfer the information of this touch to your brain - in other words, it tells you how it felt. This touch would obviously be external, or outside of your body. Nerves connected to your muscles transfer information like how your muscles feel after hard exercise, or directions from your brain on how to move a muscle - I'm using my arm muscles and my finger muscles right now to type this answer for you! This would be internal.
The decline was attributed to a number of factors including Increased insect resistance, the development of more effective alternative pesticides, public and user concern about negative environmental side effects—and a government ban on DDT use since 1969--all contributed to the decline.
