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.
After vitamin B12, the group of nutrients most likely to be deficient in a vegetarian meal plan are protein, vitamins B3 and B6, zinc, and selenium. For some practical suggestions here, let's take each of these nutrients in order. Protein: We've got to give a special nod to soybeans here.
