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.
Impulse conduction-an impulse is simply the movement of action potentials along a nerve cell. Action potentials are localized (only affect a small area of nerve cell membrane). So, when one occurs, only a small area of membrane depolarizes (or 'reverses' potential).eurons & the Nervous System. The human nervous system consists of billions of nerve cells (or neurons)plus supporting (neuroglial) cells. Neurons are able to respond to stimuli (such as touch, sound, light, and so on), conduct impulses, and communicate with each other (and with other types of cells like muscle cells).
