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.
Sensory neurons transmit nerve impulses toward the spinal cord and the brain. Motor neurons transmit nerve impulses from the brain and the spinal cord to the muscles and the glandular tissue. Multipolar neurons, bipolar neurons, and unipolar neurons are classified according to the number of processes they extend to the different kinds of neurons. Multipolar neurons have one axon and several dendrites, as do most of the neurons in the brain and the spinal cord. Bipolar neurons, which are less numerous than the other types, have one axon and only one dendrite. Unipolar neurons have one axon and no dendrites. All primary sensory afferents and some autonomic neurons are unipolar. All neurons have one axon, and most have one or more dendrites and have a slightly gray color when clustered, as in the nuclei of the brain and the spinal cord.
