Rosemary is added to dog food because it is an antioxidant and acts as a natural food preservative. Rosemary is a very common ingredient in dog food. We found rosemary or rosemary extract is in about 36% of all dog foods. It is much more common in dry foods-rosemary is present in 57% of all dry foods-most likely due to the fact that it is a natural preservative.
Interneurons connect sensory and motor neurons and interpret the impulse. Motor neurons carry impulses from the brain and spinal cord to muscles or glands. 1  Draw and label the structure of a typical nerve cell. 2  Explain how an impulse moves along a neural pathway.
Nerve impulses are electrical energy signals; and, they creates energy-fields around the body and electro-magnetic energy waves that can travel away from the body. Human electricity energy is generated by chemical processes in nerve cells. Billions of nerve impulses travel throughout the human brain and nervous system. A nerve impulse is a wave of electrical activity that passes from one end of nerve cell to another.
