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.
In this case, seasonal vitamin D supplementation would be beneficial. The most common vitamin and mineral deficiencies, especially for vegetarians and vegans, are in iron, calcium, vitamin D and B12. Vegan sources of calcium include leafy green vegetables (like spinach and kale), almonds and sesame seeds. Many milk and yogurt alternatives are also calcium-fortified.
