Each neuron consists of a cell body or perikaryon, from which arise the nerve fibers. And each neuron has two kinds of fibers: a single axon, which conveys nerve impulses away from the cell body, and one or more dendrites, which convey nerve impulses towards the cell body. Neurons are functionally linked by their fibers at connections called synapses. All neurons are post-mitotic.
However, unbalanced vegetarian diets may be lacking in a number of important nutrients. To ensure that you are eating a balanced vegetarian diet, you should regularly consume sources of vitamin B-12, iron, zinc, omega-3 fatty acids and essential amino acids.
Lacto-ovo and lacto-vegetarians can help elevate their B12 vitamin intake by consuming vegetarian foods that have been fortified with vitamin B12. A number of vegetarian and vegan foods, such as breakfast cereals, soy milk and yeast extracts, are available that contain vitamin B12, according to the Vegetarian Society.he most common sources of dietary vitamin B12 are meat and seafood products, which can make it hard for vegetarians to get enough vitamin B12 in their diet. Maintaining healthy vitamin B12 levels requires vegetarians to regularly consume appropriate foods and/or supplements that are rich in this essential nutrient.
