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.
There are three classes of neurons: 1  Sensory neurons carry information from the sense organs (such as the eyes and ears) to the brain. 2  Motor neurons control voluntary muscle activity such as speaking and carry messages from nerve cells in the brain to the muscles. 3  All the other neurons are called interneurons.
