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.verything we think and feel and do would be impossible without the work of neurons and their support cells, the glial cells called astrocytes (4) and oligodendrocytes (6). Neurons have three basic parts: a cell body and two extensions called an axon (5) and a dendrite (3).
